Auricular Acupuncture in the Treatment of Cocaine/Crack
Abuse: A Review of the Efficacy, the Use of the National
Acupuncture Detoxification Association Protocol, and the
Selection of Sham Points
ATTILIO D’ALBERTO, B.Sc.
ABSTRACT
Background: The United Kingdom has had a significant increase in addiction to and use of cocaine among
16–29-year olds from 6% in 1998 to 10% in 2000. In 2000, the United Kingdom had the highest recorded consumption of “recent use” cocaine in Europe, with 3.3% of young adults. Acupuncture is quick, inexpensive,
and relatively safe, and may establish itself as an important addiction service in the future.
Aim: To select investigations that meet the inclusion criteria and critically appraise them in order to answer
the question: “Is acupuncture effective in the treatment of cocaine addiction?” The focus shall then be directed
toward the use of the National Acupuncture Detoxification Association (NADA) protocol as the intervention
and the selection of sham points for the control group.
Data sources: The ARRC database was accessed from Trina Ward (M. Phil. student) at Thames Valley University. AMED, MEDLINE® and Embase were also accessed along with “hand” searching methods at the British
library.
Inclusion and exclusion criteria: People addicted to either cocaine or crack cocaine as their main addiction, needle-acupuncture, single-double-blinded process, randomized subjects, a reference group incorporating
a form of sham points. Exclusion criteria: use of moxibustion, laser acupuncture, transcutaneous electrical nerve
stimulation (TENS) electroacupuncture or conditions that did not meet the inclusion criteria.
Quality assessment: The criteria set by ter Riet, Kleijnen and Knipschild (in 1990); Hammerschlag and Morris (in 1990); Koes, Bouter and van der Heijden (in 1995), were modified into one set of criteria consisting of
27 different values.
Results: Six randomized controlled trials (RCTs) met the inclusion criteria and were included in this review.
All studies scored over 60 points indicating a relatively adequate methodology quality. The mean was 75 and
the standard deviation was 6.80. A linear regression analysis did not yield a statistically significant association
(n ⫽ 6, p ⫽ 0.11).
Conclusions: This review could not confirm that acupuncture was an effective treatment for cocaine abuse.
The NADA protocol of five treatment points still offers the acupuncturist the best possible combination of
acupuncture points based upon Traditional Chinese Medicine. Throughout all the clinical trials reviewed, no
side-effects of acupuncture were noted. This paper calls for the full set of 5 treatment points as laid out by the
NADA to be included as the treatment intervention. Points on the helix, other than the liver yang points, should
be selected as sham points for the control group.

INTRODUCTION
Prevalence of cocaine addiction in the
United Kingdom
A
ddiction is defined as: “Use of a substance that is addictive when it has a mixture of pleasant and unpleasant properties, nearly all of which make the organism function worse, but which also, with continued use, suppress the
organism’s awareness of most of the pleasant toxic properties” (Smith, 1979). In the United Kingdom there has been
a significant increase in the use of and addiction to cocaine
among 16–29 year olds from 6% in 1998 to 10% in 2000.
A statistically significant correlation was found between arrestees who tested positive for drug use and all four measures of criminal behavior. Half of the arrestees held for burglary of nondwelling premises tested positive for cocaine/
crack (DrugScope, 2001). Problem drug use is defined as:
“Injecting drug use or long-duration/regular use of cocaine
and/or amphetamines.” In 2000, the United Kingdom had
the highest recorded consumption of “recent use” cocaine
in Europe, with 3.3% of young adults (Fig. 1). Cocaine is a
stimulant drug extracted from leaves of the Erythroxylon
coca bush and was developed to treat a wide variety of illnesses in the mid-19th century. The chemical name of the
processed drug is cocaine hydrochloride and is generally
sold “on the street” as a crystalline powder (European Mon-
itoring Center for Drugs and Drug Addiction, 2001; United
Nations, 2000).
Past research on cocaine users showed that firm boundaries distinguish recreational users of cocaine powder (hydrochloride) from problem “base/crack” users, and cocaine
injectors (homeless young people, sex workers, and problem heroin users in geographic patches within specific
cities). However, the boundary between powder cocaine and
base/crack may be weakened by an emerging trend in cocaine smoking in recreational and nightlife settings and in
recent changes in the market (DrugScope, 2001; European
Monitoring Center for Drugs and Drug Addiction, 2001).
The United Kingdom has one of the lowest prices of cocaine in Europe; ($60.63) and a generally high purity rate
(European Monitoring Center for Drugs and Drug Addiction, 2002; Panorama, 2003). Acupuncture is quick, inexpensive, and relatively safe, and may establish itself as an
important addiction service for the treatment of cocaine addiction in the future.
Auricular acupuncture
Auricular acupuncture points have been characterized as
discrete anatomic loci measuring approximately 1–5 mm in
diameter in the auricles (Falk et al., 2000). The first record
of the auricles importance was recorded in the Huang Di
Nei Jing, Chapter 28 of the Spiritual Axis (circa 100 BCE):
“All the vessels congregate in the ear.” During the 1950s
Nogier first developed the practice of auricular acupuncture
using the concept that each part of the body is represented
on the ear. Wen and Cheung (1973a, 1973b, 1973c) further
developed the use of auricular acupuncture in alleviating the
addiction to opiate-based drugs. In 1985, Michael Smith
M.D., Lincoln Hospital, Bronx, New York, developed this
research into the newly formed National Acupuncture
Detoxification Association (NADA) protocol.
The number of points on the auricle remains unclear; the
number ranges from 43 to 900, depending on the author
(Chen, 1991). Acupuncture acts to relieve withdrawal symptoms and prevent the craving for drugs (Smith and Khan,
1988). The standard NADA points are Shenmen, Sympathetic, Kidney, Liver, and Lung (Fig. 2).
Mechanisms of acupuncture
FIG. 1. Recent use (last 12 months) of cocaine among young
adults, measured by national population surveys (European Monitoring Centre for Drugs and Drug Addiction, 2002, p. 12).
Cocaine is believed to exert its euphoric effects by
blocking the reuptake of neurotransmitters (primarily
dopamine) at nerve synapses in the brain. As a dopamine
reuptake inhibitor, cocaine can be considered to be an indirect dopamine agonist because it potentates the synaptic actions of dopamine that have been released endogenously (Xenova Group Plc, 2003). Blum and colleagues
(1996) suggested that stimulating the vagus nerve, which
is located in the concha and at the Lung point on the auricle (Fig. 2) with the insertion of an acupuncture needle,
stimulates the hypothalamus. Under normal conditions,

ment for cocaine addiction are increasing (European Monitoring Centre for Drugs and Drug Addiction, 2001).
Legislation introduced in March 2001 by the U.K. government regulated the testing and related procedures on individuals suspected of driving under the influence of illicit
substances (European Monitoring Centre for Drugs and
Drug Addiction, 2002). Coupled with existing drug laws,
the number of cocaine users being arrested has increased.
Arrest–referral schemes and drug treatment and testing order schemes (DTTOs) have been found useful in the United
Kingdom to increase the number of drug-using offenders in
treatment. Research conducted by the DPAS (2000) demonstrated that the crisis of arrest is an important opportunity
to target drug-misusing offenders with prevention and treatment services.
No medication has received widespread acceptance as an
effective treatment for cocaine dependency (Rawson et al.,
1990). Although some withdrawal treatment interventions
have been subject to evaluation, more in-depth knowledge
is needed in the pros and cons of the different modalities
and on which type of withdrawal treatment should be used
for which type of patient (European Monitoring Centre for
Drugs and Drug Addiction, 2002). Drug treatment can be
divided into the stages of detoxification, rehabilitation, and
relapse prevention. Acupuncture has been used for all stages
of drug treatment (Moner, 1996; Scott and Scott, 1997).
AIM OF THIS STUDY
hypothalamic stimulation initiates the reward cascade. Hypothalamic neurons release serotonin (5HT), which activates methionine enkephalin, an opioid peptide. Metenkephalin is released at the ventral tegmental region and
interacts to inhibit receptors controlling the release of ␥aminobutyric acid (GABA). Met-enkephalin and/or other
opioid peptides finely tune the system. The primary role
of GABA is to control the output of dopamine in the ventral tegmental region. The result of inhibiting GABA is an
increase in dopamine. Acupuncture acts to reduce craving, thereby assisting the drug addict into self-recovery.
The NADA points act to tonify the yin of the Liver, Lung,
Kidney, Heart (Shenmen) and the Sympathetic region, although this hypothesis of treatment effect has not been investigated within a Western biomedical framework.
Justification for a review of literature
The impact of national drug policies (more liberal versus
more restrictive approaches) on problem drug use remains
unclear because prevalence rates in countries with liberal
drug policies (such as The Netherlands) and those with a
more restrictive approach (such as Sweden) are not very different. What is clear is that new clients seeking treatment
for heroin addiction are decreasing while those seeking treat-
The aim of this study was to select investigations that
meet the inclusion criteria and appraise them critically in order to answer the question: “Is acupuncture effective in the
treatment of cocaine addiction?” The focus shall be directed
toward the use of the NADA protocol as the intervention
and the selection of sham points for the control group.
MATERIALS AND METHODS
Data sources
A literature search was performed using ARRCBASE,
MEDLINE® (1966–present), AMED (1985–present), and
Embase (1989–present). Also “hand searching,” manual
methods were used at the British Library, to capture items
that may have been indexed incorrectly or not indexed at
all (Sim and Wright, 2000). Examination of reference lists
in primary and review articles were conducted. Copies of
original articles were obtained at all times so as to capture
an undiluted source of data. Only full-length, English-language articles were sought. Abstracts and unpublished studies were not selected. Inclusion and exclusion criteria were
then applied to establish the final set of articles to be reviewed.

Inclusion and exclusion criteria
Studies were included in this review if they met the criteria: people addicted to either cocaine or crack cocaine as
their main addiction, needle-acupuncture, single-doubleblinded process, randomized subjects, a reference group incorporating a form of sham points. The inclusion group also
consisted of pilot studies. Studies that were rejected used
moxibustion, laser acupuncture, transcutaneous electrical
nerve stimulation (TENS) electroacupuncture, or did not
meet the inclusion criteria.
score for each study was 100 points. The higher the score,
the better the quality of the methodology. One assessor conducted the grading. The assessor was not blinded to the outcomes of the studies included in this review. This means
that some degree of reviewer bias cannot be excluded (ter
Riet et al., 1990). In instances where data were missing to
correlate the studies to the grading criteria, authors were contacted and the necessary information gathered (S. Avants,
personal communication, November 11, 2003; T. Kileen,
personal communications, 2003; D. Lipton, personal communication, November 11, 2003; A. Margolin, personal
communication October 29, 2003).
Key words
The key words used by the administrator of the ARRC
database were “cocaine” and “acupuncture” (T. Ward personal communication, July 17, 2003). These key words were
further used during searches of other electronic sources.
Quality assessment
All randomized controlled trials (RCTs) were evaluated
to determine the quality of the studies. The ter Riet et al.
strategy (1990) was considered first but was criticized for
only having a series of 18 criteria that limited the ability to
adequately score the clinical trials (Birch, 2001; Lewith,
1995). Birch (2003) suggests a criteria range of 43, but remains unpublished. The ter Riet et al. criteria was therefore
modified to include criteria from Hammerschlag and Morris (1990) and Koes et al. (1995). This selection of criteria
was thought to be more comprehensive to enable this study
to answer the research question. Twenty-seven (27) different criteria were set (Appendix A) A weighting was attached
to indicate its relative importance. The potential maximum
FIG. 3.
RESULTS
Six RCTs met the inclusion criteria and were included in
this review (Avants et al., 2000; Bullock et al., 1999; Killeen
et al., 2002; Lipton et al., 1994; Margolin et al., 2002a; Otto
et al., 1998). Appendix B presents the results of the methodological assessment of the RCTs in a linear order. Appendix C summarizes all six studies. “Half-points” were given
if the assessor felt that the research paper had succeeded partially a defined criteria (Appendix D). Because only one assessor graded the RCTs, these results are considered to be
preliminarily only.
Of the six RCTs reviewed, two reported a positive outcome (Avants et al., 2000; Lipton et al. 1994) while four
were negative in their conclusions (Bullock et al., 1999;
Killeen et al., 2002; Margolin et al., 2002a; Otto et al., 1998).
All studies scored over 60 points indicating a relatively adequate quality of methodology. The highest score was 83
(Bullock et al., 1999) while the lowest was 64 (Killeen et
al., 2002) (Fig. 3). The mean was calculated at 75 with a

standard deviation of 6.80. A linear regression analysis did
not yield a statistically significant association (n ⫽ 6, p ⫽
0.11). All studies scored full points on criteria 1, 2, 3, 5, 10,
11, 13, 15, 22, 25, and 26. No criteria scored zero across all
studies.
Of the six studies, three excluded the Kidney point from
the NADA protocol (Table 1). Three studies used proximal
points, three used helix points, two of which avoided Liver
yang points on the helix while one did not avoid the Liver
yang points.
DISCUSSION
There have been many statements made against the use
of RCTs in the study of acupuncture (Birch, 2003; Falk et
al., 2000; Given, 1997; Guillaume, 1991; Margolin et al.,
1998a; McLellan et al., 1993; Sherman et al., 2001; Suen et
al., 2000). However, until a protocol is found that suits both
paradigms of allopathic and traditional medicine, then current methodological criteria for RCTs remain the gold standard.
Looking at the RCT scoring, all studies scored more than
60 points, indicating that the RCTs had a good quality of
methodology. However, a paradox exists; all studies scored
better than average, yet had conflicting outcomes. The study
by Lipton et al. (1994) has a positive outcome toward auricular acupuncture and a methodology score of 77, while
the study by Margolin et al. (2002a) was negative in its conclusions yet achieved a scoring of 79. Therefore, this review

cannot provide a definite answer as to the efficacy of auricular acupuncture in the treatment of cocaine/crack abuse.
This raises the following question: In spite of apparently
good overall quality of methodology, are certain methodological criteria within the clinical studies of the effects of
auricular acupuncture on cocaine abuse causing contradictory outcomes?
The selection of treatment points versus sham points is
the most important aspect of any acupuncture research, especially research still in development. If “sham points” have
active (positive) effects, the comparison of outcomes between the “treatment” and “sham” groups cannot show the
true effect of acupuncture treatment, and the conclusion that
treatment “had no significant effect” can be seriously wrong
because the “sham” points were inappropriate.
The first documented research in auricular acupuncture
and cocaine addiction started in the 1970s (Wen et al.,
1973a, 1973b, 1973c). Since then, other studies have tried
to replicate these findings in a more strict empirical clinical
setting. Lipton et al. (1994), the first group to replicate the
studies of Wen et al. (1973a, 1973b, 1973c), concluded that
acupuncture gave a positive outcome (Table 1). Further studies found flaws in Lipton et al.’s (1994) selection of sham
points proximal to sham points in the control group undermining the outcome result (Birch, 2003; Culliton and Kiresuk, 1996; Margolin et al., 1995, 1998a) Otto et al. (1998)
and Bullock et al. (1999) both replicated the study by Lipton et al. (1994) and concluded with negative outcomes. In
both of these replicated studies, inappropriate sham points
(proximal to active points) were used in the control group.

Avants et al. (2000) used the newly developed selection of
sham points on the auricular helix, although with a reduced
number of treatment points, four instead of the standard five
set by the NADA. They concluded with a positive outcome.
Killeen et al. (2002) used the full set of NADA points and
nonproximal auricular points but it is unclear which points
were selected on the helix. Liver yang points may have been
stimulated in the control group, thus flawing the control as
a neutral intervention (Birch, 2003; T. Killeen, personal
communication, November 11, 2003). Margolin et al.
(2002a) replicated Avants et al. (2000) study by correctly
using the helix without stimulation of the Liver yang points
and excluded the Kidney point from the NADA treatment
group. The outcome was negative.
Traditional Chinese Medicine (TCM) comprises a large
and heterogeneous group of treatments, many of which are
procedures not readily testable under blinded conditions and
for which the choice of appropriate control conditions is by
no means straightforward especially when compared to control procedures for pharmacotherapies. TCM has a theoretical basis, rooted in a cultural tradition that has little foundational research on which to base a controlled evaluation
(Margolin et al., 1998b, 2002b). Therefore, and because it
does not include the concept of a “placebo,” TCM sheds little light on the issue of the selection of sham points.
There may be no “inactive” or “placebo” sites suitable
for “negative controls” in acupuncture research. Sites far
outside the active area may not be neutral. They may cause
pain and thus would not be an appropriate sham or inactive
placement, or may elicit a physiologic response that is considered by some to be another form of acupuncture and not
a true placebo (Culliton et al., 1996; McLellan et al., 1993;
Moner 1996).
Classically defined, a placebo effect is an effect that occurs after the administration of a therapeutically inactive
substance, such as a lactose pillule, or a small dose of a weak
saline solution. Nonspecific effects are those that occur after treatments that do not use medication or procedures with
known or presumed mechanisms for their action (Culliton
et al., 1996). In any study, both active and sham points must
be correctly located, especially upon a body–mass as small
as the auricle. To do so requires detailed and accurate charts
of points and anatomic locations. All the studies reviewed
relied upon ear maps. In the latest study by Margolin et al.
(2002a), the location of sham points is referenced to one paper, namely Margolin et al. (1995). In the 1995 study, the
location of the actual sham points was explained but poorly
described. There was no reference to any auricular maps or
standardized nomenclature. The currently accepted selection
of sham points on the helix originated in the study by Margolin et al. (1995). A later study by Margolin and colleagues
(1996) confirmed the hypothesis that points on the helix had
a lower electrical resistance than those located proximal to
active points. The ear charts used to identify the location of
the active and sham points were those of Cheng (1999),
D’ALBERTO
Manaka et al. (1995), and O’Connor and Bensky (1981).
These ear charts differ greatly on the number of points, Manaka et al. (1995), number 108; O’Connor et al. (1981) 180;
while Cheng (1999) number 79. Margolin et al. (1996), simply refer to these points as zone 1, 2, 3, and 4 and assumed
that zones, as distinct regions of the ear, do in fact exist, that
zones had well-defined and specific locations, that zones
were congruent across subjects despite variations in auricular shape, and that zone quadrants had similar orientation
across subjects, although this may not be the case.
Without a standard auricular nomenclature, it is difficult
to see how studies used the ear charts to determine correct
point location. The conclusion of all the studies reviewed,
were made upon the findings derived from insertion of needles into “points.” Confusion of names and locations of auricular points has seriously hindered the development of auricular therapy (Suen et al., 2000).
At present no auricular nomenclature exists. There are
great differences between the French and Chinese systems.
At present only 39 auricular points have been agreed upon
(Oleson 1998; World Health Organization, 1990). Some
points have more than one name and new points are constantly being added with new clinical discoveries (T. Oleson, personal communication, October 30, 2003). The
Working Group of the WHO decided to withdraw its earlier Auricular Acupuncture Chart because it contained many
points and should not be used for the purpose of further reference to localization of auricular points, or be used in view
of the changes in the standardization of the anatomy of the
areas of the ear (World Health Organization, 1990). There
is a great need for standard terminology in the study of auricular acupuncture. There should be a standard reference
chart of the ear that covers the following:
• Correct anatomic illustrations of the ear.
• An appropriate anatomical mapping of topographical areas, to be decided upon in consultation with experts in
anatomy and auricular acupuncture.
• Illustrations of correct zones, in relation to auricular
acupuncture and research.
• Actual delineation and localization of points, where possible (World Health Organization, 1990).
Oleson (1998) outlined a possible standardization of auricular nomenclature and will present his proposal as a journal article soon (T. Oleson, personal communication, October 30, 2003).
Relocation of sham points to the helix has assisted in the
study of the NADA treatment protocol. Introduced of this
standardized form of treatment helped to bring auricular
acupuncture into the frame of empirical testing, although
some have criticized that the standard form of treatment offered by the NADA is against the theoretical foundation of
syndrome-differentiation-symptom pattern analysis that is
essential in TCM (Given, 1997). Within all six studies the
991
NADA PROTOCOL
NADA protocol or an amended version were used as the
treatment intervention. However, there is no factual or scientific explanation for the selection of the five NADA points
(Konefal et al., 1995; McLellan et al., 1993).
To understand acupoint selection as a treatment modality, it is necessary to understand addiction according to TCM
and the role of the NADA protocol. The NADA protocol is
based upon the understanding and relationship of the body’s
internal organs, known as the Zangfu. In TCM theory, drug
abuse affects mainly the solid (zang, yin) organs: Lung,
Liver, Heart, Spleen, and Kidney.
Cocaine abuse generally leads sequentially to four particular syndromes in TCM, which outline the pathology of
drug abuse among the Zangfu.
1. Heart yin deficiency: nonpurposive symptoms: excessive
sweating, insomnia and anxiety (Maclean and Lyttleton,
1998; Smith, 1979).
2. Kidney yin deficiency: purposive symptoms: paranoia
(Smith, 1985).
3. Liver yin deficiency: purposive symptoms: irritability,
euphoria, and anger (Brewington et al., 1994; Smith,
1979).
4. Spleen qi deficiency: nonpurposive symptoms: diarrhea
and loss of appetite.
With the effects of withdrawal and excessive sweating,
cocaine destroys Heart yin and causes yang to be greater
than yin because a weakened yin cannot balance or regulate
yang (Dale, 1993). TCM terms this situation as “Empty Fire”
or “False Fire.” Because Kidney and Heart have a unique
relationship according to the Ko (Controlling) sequence of

the Five Element Theory (Fig. 4), Empty/False Fire drains
Kidney yin. Kidney (Water–Mother of Fire) regulates and
controls the Heart (Fire–Child of Water). As the abuse of
cocaine depletes Heart yin, which allows Heart Fire to arise,
Kidney yin is further depleted by excessive demand leading
to the syndrome of Kidney yin deficiency. This is known as
Heart insulting Kidney.
Via the Sheng (Generating) sequence of Five Element
Theory (Fig. 5), Kidney yin deficiency then inhibits Kidney
(Mother of Wood) in its function of supplying yin to Liver
(Wood, Child of Water), creating the Syndrome Liver yang
Rising. The pathologic yin and yang mechanisms are the
same as that of the Kidney–Heart relationship, although in
this instance it is housed within the one organ. Liver yang
Rising further exacerbates the Heat Syndrome and yin depletion. The more deficient the yin, the greater the Liver
yang Rising. This leads to a greater degree of yin deficiency
and perpetrates the cycle of yin deficiency. The yin depletion cycle moves back to the Kidney, which is the foundation for all the yin energies of the body (Maciocia, 1989)
(Fig. 6).
Liver imbalance leads to the Syndrome Liver–Spleen
disharmony. Here Liver invades Spleen causing spleen deficiency. Excessive loss of bodily fluids worsens the yin deficiency, because yin is essentially water. Injury to Spleen
inhibits its function of generating qi and Blood for the whole
body. This drains the body’s reserves Pre-Heaven qiEssence housed within the Kidney and increases the Kidney
yin deficiency.
Many addicts are involved in excess sexual activity that
damages Kidney yin. Chronic drug abuse may damage Kidney yang as well as Kidney yin. The abuse of sex that results from the False yang (Empty Heat) increases the yin

and jing (Essence) deficiency, which further exacerbates the
False yang. In some patient populations, the addiction to and
abuse of sex is a primary motivation for the abuse of the
drug and these people may be addicted to the False yang itself (Dale, 1993; Given, 1997; Smith, 1985).
Allopathic medicine also recognizes the relationship between cocaine abuse and kidney damage. A wide spectrum
of renal complications can occur with cocaine use, including renal infarction, atherosclerosis of the kidney, renal scleroderma, Henoch-Schönlein purpura, and renal failure as a
result of rhadbomyolysis (Crowe et al., 2000).
In the six studies reviewed, the NADA protocol was modified to exclude the Kidney point in certain instances (Avants
et al., 2000; Lipton et al., 1994; Margolin et al., 2002a). Lipton et al. (1994) and Avants et al. (2000) do not provide any
reasoning for the exclusion. In the study by Margolin et al.
2002a, the justification was to avoid hyperstimulating the
auricle in the control condition. There is no clinical evidence
that suggests the Kidney point hyperstimulates the auricle
in either the NADA protocol or the control group, including the debunked sham protocol of points 2–3 mm away
from active sites or the newly developed control protocol of
points located on the auricular helix. Margolin et al. (2002a)
used dubious reference literature to justify their four-point
selection. Their literature consisted of five articles: Bullock
et al. (1989); Lipton et al. (1994); Avants et al. (1995); Bullock et al. (1999); Avants et al. (2000). Of these five studies, two (Avants et al., 2000; Lipton et al., 1994) gave no
logical reasoning for the exclusion of the Kidney point. One
study (Bullock et al., 1999) included the Kidney point while
two studies (Bullock et al., 1989; Avants et al., 1995) excluded both the Liver and Kidney point. There is therefore
no logical reasoning to exclude the Kidney point in any clin-
ical trial conducted to date. The NADA training manual does
not stipulate the sole exclusion of the Kidney point as stated
by Margolin et al. (2002a). Sometimes fewer points may be
used on clients if they are for example, feeling very sensitive or delicate, or they are young, 14 or 15 years old. Then
it is a case of using less points rather than excluding one in
particular (R. Peckham, personal communication, November 23, 2003). Any competent TCM practitioner qualified
in acupuncture knows that the Kidney point must be used
as the main point of treatment to reduce drug cravings.

11, 2003) cites an earlier study (Margolin et al., 1998a) that
justifies the exclusion of the Kidney point in the Avants et
al. (2000) study. Margolin et al. (1998a) suggested a reason
to exclude the Kidney point—because unnamed “acupuncturists” wanting to achieve a lower “activity.” It is speculated here, that the idea of using points of lower “activity”
arose from Ulett’s research into stimulation by frequency
specific instruments of auricular point Lung (Fig. 2). The
Lung point lies in concha of the ear, which is the place of
greatest density of vagal innervation. Ulett—who based his
research on the Wen et al. [1973b] study—claimed that only
one point bilaterally is necessary. If point selection is to be
based on the understanding of the acupuncture mechanics
alone rather than the selection of the NADA points, then
only the Lung point need be used (Blum et al., 1996; McLellan et al., 1993; Ulett, 1992). The landmark auricular study
by Wen et al. (1973b), used only the Lung point until the
subject felt they had the full dose of their addictive drug,
with good results. There is no evidence as claimed by Avants
that warrants the exclusion of the Kidney point.
Bullock et al. (1999) suggested another theory why the
Kidney point was excluded from the traditional five-point
NADA protocol. They excluded the Kidney point in relation to the now debunked use of proximal point selection
2–3 mm away from the active NADA points. Within this
form of control, it was deemed necessary to reduce the number of needles in an effort to reduce “stimulus flooding.” Although it was not stated clearly, this may be related again
to the idea to avoid hyperstimulation of the vagus nerve located at the auricular Lung point.
The NADA selection of points, including the Kidney, reduces the signs and symptoms of drug abuse and withdrawal
(Given, 1997; Konefal et al., 1995; Margolin et al., 1993b;
Richard et al., 1995; Smith, 1979; Smith et al., 1988). Using frequent repetitions of Kidney-related ear treatments is
very effective in even severely debilitated addicts; in such
cases the main treatment focus is to tonify the Kidney (Dale,
1993; Smith, 1985). By tonifying the Jing-Essence and
strengthening the Kidney, rehabilitated patients can return
to function on the every-day expected level of Jing function. Patients need ear–Kidney treatments before they are
able to respond to other acupuncture. It cannot be overemphasized the critical importance of using ear-Kidney treat-

ment as the primary form of acupuncture for chemical dependency (Smith, 1985).
Clearly there has been an inadequate knowledge of the
nature and scope of acupuncture leading to the selection of
inappropriate treatment methods and sham point selection
in many studies. The lack of nomenclature in auricular
acupuncture increases the problem. These problems illustrate the necessity for more cooperative efforts to determine
the best research methodologies to use (Birch 2003).
ate release or hormonal changes occur with sham points located on the auricular helix to assess if the sham treatment
is truly placebo.

CONCLUSIONS
Implications for professional practice
Even though this review could not confirm the efficacy
of acupuncture to treat cocaine abuse, the NADA five-point
protocol offers the acupuncturist the best possible combination of acupoints based on TCM theories. Throughout all
the clinical trials reviewed, it was impressive to note the low
rate of side-effects with the acupuncture treatment (Margolin
et al., 1993a; McLellan et al., 1993; Moner, 1996). Acupuncture is highly cost-effective. Overhead costs are low, equipment needs are negligible, and therapy is easily given on an
outpatient basis. Also, one acupuncturist, supported by a
small ancillary staff, can treat many patients simultaneously.
Finally, increased use of acupuncture therapy may eventually decrease in the number of inpatient admissions to expensive treatment centres (Bullock et al., 1989).
Implications for research
The inconsistency in treatment protocols between studies, or the use of combined therapies, makes it impossible
to draw a strong causal relationship between auricular therapy and its treatment effect, thus making replication of studies difficult (Suen et al., 2000). As the form of auricular
acupuncture control has moved away from sites located 2–3
mm away from active sites to those located on the helix,
there is a call for the reintroduction of the Kidney into the
acupuncture treatment protocol. This may enhance treatment
effectiveness and provide clarity in future clinical trials
studying the effects of auricular acupuncture for crack/cocaine abuse. This paper calls for the standardization of
methodology in be implemented systematically to all clinical studies researching the effects of auricular acupuncture
on crack/cocaine abuse. The full five treatment points proposed by the NADA should be used at the treatment intervention. Points on the helix, other than the Liver yang points,
should be selected as sham points for the control group. It
is hoped that by doing so, clear studies can be conducted
that will effectively conclude an outcome for the use of auricular acupuncture in the treatment of cocaine/crack abuse.
Additional studies are needed to evaluate if endogenous opi-
