    A substantive amendment to this systematic review was last made on 17 June 1999.

    Cochrane reviews are regularly checked and updated if necessary.

    Background and objectives: Acupuncture is promoted as a treatment for smoking

    cessation, and is believed to reduce withdrawal symptoms. The objective of this review is

    to determine the effectiveness of acupuncture in smoking cessation in comparison with:

    a) sham acupuncture

    b) other interventions

    c) no intervention.

    Search strategy: We searched the Cochrane Tobacco Addiction Group trials register,

    Medline, Psyclit, Dissertation Abstracts, Health Planning and Administration, Social

    SciSearch, Smoking & Health, Embase, Biological Abstracts and DRUG.

    Selection criteria: Randomised trials comparing a form of acupuncture with either sham

    acupuncture, another intervention or no intervention for smoking cessation.

    Data collection and analysis: We extracted data in duplicate on the type of subjects, the

    nature of the acupuncture and control procedures, the outcome measures, method of

    randomisation, and completeness of follow-up.

    We assessed abstinence from smoking at the earliest time-point (before 6 weeks), at six

    months and at one year follow-up in patients smoking at baseline. We used the mostrigorous definition of abstinence for each trial, and biochemically validated rates if

    available. Those lost to follow-up were counted as continuing to smoke. Where

    appropriate, we performed meta-analysis using a fixed effects model.

    Main results: We identified 18 publications involving 20 comparisons. Acupuncture was

    not superior to sham acupuncture in smoking cessation at any time point. The odds ratio

    (OR) for early outcomes was 1.22 (95% confidence interval 0.99 to 1.49); the OR after 6

    months was 1.38 (95% confidence interval 0.90 to 2.11) and after 12 months 1.02 (95%

    confidence interval 0.72 to 1.43).

    Similarly, when acupuncture was compared with other anti-smoking interventions, there

    were no differences in outcome at any time point. Acupuncture appeared to be superior to

    no intervention in the early results, but this difference was not sustained.

    The results with different acupuncture techniques do not show any one particular method

    (i.e. auricular acupuncture or non-auricular acupuncture) to be superior to control

    intervention.

    Reviewers' conclusions: There is no clear evidence that acupuncture is effective for

    smoking cessation.

    BackgroundAcupuncture has been used in the treatment of nicotine dependence in the West since anincidental observation in Hong Kong (Wen 1973). Opium smokers who had been givenelectroacupuncture for pain relief claimed that their opiate withdrawal symptoms were less

    2/17

    severe than they expected. Uncontrolled studies have suggested that acupuncture might alsoreduce the symptoms of nicotine withdrawal and some remarkably high rates of initial successhave been claimed. For example Fuller claimed that 95% of 194 subjects were not smokingafter three treatments in one week, falling to 34% after twelve months (Fuller 1982). Choyclaimed 88% success in a large study of 514 subjects but did not state the long-term results(Choy 1983). Clearly only randomised controlled studies can determine whether this is morethan a placebo effect.Several literature reviews of controlled trials of acupuncture for smoking cessation have beenpublished yet the conclusions are not uniform. Vincent & Richardson found that acupunctureappeared to be as effective as other methods in the initial stages of nicotine withdrawal.However there was uncertainty as to what the actual stimulation contributed and whetheracupuncture helped prevent relapse (Vincent 1987). Schwartz found no evidence of a specificeffect (Schwartz 1988). Brewington et al (Brewington 1994) concluded that acupuncture mightbe of limited assistance in withdrawal.Ter Riet (Ter Riet 1990) performed a criteria-based systematic review of randomised controlledtrials and found that the better the quality of the study the more likely it was to be negative. Heconcluded that on balance there was no evidence that acupuncture was efficacious in the

    treatment of nicotine addiction. Lewith criticised this review and argued that trials in which thecontrols received needling in inappropriate sites were likely to underestimate the effects ofacupuncture: the control procedure was not inactive since needling random sites could triggerthe release of endorphins (Lewith 1995). He concluded that acupuncture is as good as nicotinereplacement therapy.Law & Tang performed a limited meta-analysis of the Medline-listed trials, concluding thatacupuncture had "little or no effect" (Law 1995). Ashenden & Silagy (1997) included 10 studiesin a systematic review looking at the long-term success of acupuncture in smoking cessation: 9of the studies could be combined in a meta-analysis which concluded that, while acupunctureappears to be promising, there was insufficient evidence to recommend it as an effective form oftherapy.We undertook a new review and meta-analysis in order to evaluate the short and long-term

    outcome of acupuncture for smoking cessation.

    ObjectivesTo evaluate whether acupuncturea) has a specific effect in smoking cessation beyond placebo effectsb) is more effective than other interventions for smoking cessationc) is more effective than no treatment for smoking cessation

    Criteria for considering studies for this review

    Types of participants

    Tobacco smokers aged over 18 years who wished to stop smoking.

    Types of intervention

    Any treatment involving needle puncture of areas of the body described by the studys author asacupuncture points. This includes points on the ear, face and body. Needles usually remain inposition for the duration of a treatment session (often lasting 15 - 20 minutes). Studies in whichan electrical stimulation was applied to the needles, known as electroacupuncture, were alsoincluded.Alternatively, or in addition, to the above needling, specially designed indwelling needles maybe inserted, usually in ear points, and held in position with surgical tape for several days.Patients are instructed to press the indwelling needles when they become aware of withdrawalsymptoms. As alternatives to indwelling needles, either small seeds may be attached to the earwith adhesive tape, or a surgical suture may be inserted and knotted with a bead attached.Such studies were also included in the review.

    Types of outcome measures

    Only complete abstinence from smoking was considered. The review has not been limited tostudies where the outcome was confirmed biochemically (see 'Methodological quality'). Wherenecessary the published data have been recalculated on an intention-to-treat basis i.e. countingall drop-outs as smokers.

    Data have been extracted (where they are presented in the report) on early outcome (i.e. firstmeasure after the treatment, but in any case less than 6 weeks) and after 6 and 12 months.Sustained smoking cessation was chosen in preference to point prevalence where these figureswere available.

    Types of studies

    All randomised controlled trials comparing acupuncture with either sham acupuncture, anotherintervention or no treatment, for smoking cessation.

    Search strategy for identification of studiesSee: Collaborative Review Group search strategy

    All publications containing the terms "smoking" and "acupuncture" were identified usingcomputerised searches of MEDLINE, PSYCLIT, DISSERTATION ABSTRACTS, HEALTHPLANNING & ADMINISTRATION, SOCIAL SCISEARCH, SMOKING & HEALTH, EMBASE,BIOLOGICAL ABSTRACTS and DRUG (a database maintained by the Alcohol and other DrugsCouncil of Australia). In addition, relevant references were obtained from published reviews,clinical trials and conference abstracts, as well as smoking and health bulletins andbibliographies.

    Methods of the reviewData for smoking cessation rates early after treatment (the first recorded, but less than 6 weeks)and at 6 and 12 months were extracted from the reports by ARW and HR independently.Disagreements were resolved by discussion. The reviewers were not blinded. Where possible,authors were contacted to provide missing data.Subjects lost to follow-up were regarded as having continued smoking.The three time-points were selected in an attempt to identify separately the possible effects ofacupuncture on a) cessation in the acute withdrawal period, and b) sustained abstinence.When more than one control group was used, 2 comparisons were performed, one using thedata most favorable to acupuncture and the other using the data least favorable. This situationoccurred with Circo 1985and Cottreaux 1983. However, data from control groups werecombined in the subsequent comparison of different methods of acupuncture.Data on withdrawal symptoms were not extracted; very few studies used withdrawal symptomsas an endpoint.

    Repeated comparisons were made between acupuncture and different control procedures (i.e.sham acupuncture, other active treatment control, and no intervention) and between differenttechniques of acupuncture. In each case a weighted estimate of the OR (with a positiveoutcome shown as >1) was calculated using the fixed effects model.Confidence intervals were set at 95%.

    Description of studiesSee: Table of included studies, Table of excluded studies18 reports were found of studies which qualified for inclusion in the review. However, Martin(1981) and Parker (1977) both reported parallel studies, i.e. two groups with different treatmentprocedures, each with its own control group. Therefore, data from each of these groups havebeen entered separately, giving a total of 20 controlled studies for analysis (see Table ofIncluded Studies).

    Initial group sizes for the study by Martin (1981) were not available in the published report andwere obtained from the authors. Results for the different arms of the study by Clavel (1990)were obtained from the authors.The studies varied considerably in methodology as well as the technique of acupuncture used.

    Methodological qualitySee: Table of included studiesWe assessed four dimensions of study design which may lead to bias in studies of smokingcessation: a) reporting of method of randomisation and allocation concealment b) blinding ofsubjects to treatment status c) verification of cessation d) duration of outcome.a) Randomisation and concealmentOnly one report included sufficient details to be certain whether correct method of randomisationwith adequate concealment was used (White 1998). Martin (1981) and Lagrue (1977)randomised subjects in groups in order to prevent individuals who were receiving differentprocedures from mixing together and attempting to guess their group allocation. Labadie (1983)randomised subjects by alternation; and Steiner (1982) used a matched pairs design. None ofthese methods is regarded as true randomisation.

    In view of the lack of information on methods of randomisation, we did not assign a formalquality score to the studies.b) BlindingA study was adjudged to be single-blind if it involved some form of sham therapy that wasdesigned to be indistinguishable to the participant, even if the word 'blind' was not specificallymentioned by the author. Single-blinded studies appear in the comparisons 'Acupuncture vssham acupuncture'.Achieving full double-blinding is problematic in acupuncture studies. One trial (Lagrue, 1977)achieved blinding of the therapist by training a novice to use the two interventions withoutknowing which was genuine.Even if subjects are blinded, they may be influenced by the interaction with the practitioner. Toavoid this, minimal or standardised interaction between therapist and patient is a recognisedmethod of reducing bias in acupuncture research. This procedure was adopted in 4 studies(Gilbey 1977, He 1997, Lamontagne 1980 and White 1998).c) Outcome measure verificationSmoking cessation was verified by biochemical testing in four of the trials: Clavel 1985 andWhite 1998used a carbon monoxide meter, He 1997 measured serum cotinine, and Waite 1998measured urinary cotinine concentrations.d) Duration of smoking cessationSince sustained cessation is the prime object of anti-smoking programmes, cessation at 12months is considered the most important outcome. However, only 5 of the 16 studies measuredoutcomes at 12 months.

    Results List of comparisons

    Acupuncture was not superior to sham acupuncture in smoking cessation at any time pointconsidered in this review. The OR for early outcomes was 1.22 (95% CI 0.99 to 1.49); the ORafter 6 months was 1.38 (95% CI 0.90 to 2.11) and after 12 months 1.02 (95% CI 0.72 to 1.43).Similarly, when acupuncture was compared with other anti-smoking interventions, there were nodifferences in outcome at any time point. The respective ORs for early outcomes were 0.80(95% CI 0.62 to 1.02) using the least favourable data, and 1.05 (95% CI 0.82 to 1.35) using themost favourable data. After 6 months the OR was 1.11 (95% CI 0.63 to 1.94) and after 12months the OR was 0.87 (95% CI 0.61 to 1.24) or, with the least favourable data, 0.76 (95% CI0.54 to 1.08).Acupuncture was only compared with no intervention in 3 studies. Acupuncture appeared to besuperior to no intervention in the early results (OR 5.88, 95% CI 2.66 to 13.01), but there was no

    5/17

    difference at 6 months (OR 0.99, 95% CI 0.30 to 3.24). The result at 12 months is dependent ononly one study, OR 2.44 (95% CI 1.15 to 5.20).The results with different techniques did not show any one particular method (i.e. auricularacupuncture or non-auricular acupuncture) to be superior to control intervention at any time-point.The sensitivity of the results to study quality was not tested because of the problems inassigning formal quality scores to this set of studies.

    DiscussionAcupuncture was not shown to be superior to sham acupuncture or any other intervention insmoking cessation. The studies included in this review are subject to a number of biases. Inparticular, the majority of studies neither reported how randomisation was performed nor verifiedsmoking cessation biochemically. However such biases might be expected to exaggerate theeffects of acupuncture rather than underestimate them.The comparisons of acupuncture and sham acupuncture reveal three studies with results thatare strongly positive and clearly different from all other results (He 1997, Lacroix 1977, Waite

    1998). No explanation for this difference can be identified in the study by Lacroix. The study byHe 1997, however, involved a combination of acupuncture approaches, with bodyelectroacupuncture, ear acupuncture and prolonged ear acupressure. The study by Waite 1998involved ear acupuncture and prolonged ear acupressure. It is possible that acupuncturestimulation that is both intensive and continuous may have an effect which is not seen with morelimited treatment, and this deserves further research.It appears that acupuncture, like some other interventions, may be better than doing nothing inorder to aid smoking cessation. However, this conclusion is based on only 3 studies, and theeffect appears not to be sustained.This negative conclusion limits rather than prohibits further investigation of the place ofacupuncture in withdrawal from habituating substances. It should be emphasised that the initialobservation of an effect of acupuncture in dependency was in patients who were in the acutestage of opiate withdrawal (Wen 1973) . Changes in opioid peptides accompanied theseobservations (Clement-Jones 1979). Animal experiments have also suggested that acupuncturemight have a place in the acute withdrawal syndrome (Cheng 1980, Choy 1978, Han 1993, Ng1975). It would seem important to study the possible effect of acupuncture in the acute stages ofnicotine withdrawal. Clavel 1990 made an attempt to measure withdrawal symptoms but lessthan a quarter of the subjects completed the questionnaires. White 1998 measured withdrawalsymptoms in those who were successful in stopping smoking and found no effect ofacupuncture compared with sham. The effect of prolonged ear acupressure on withdrawalsymptoms remains untested.

    Reviewers' conclusions

    Implications for practice

    There is no evidence for the specific effectiveness of acupuncture in smoking cessation greaterthan a placebo effect.

    Implications for research

    Future research should concentrate on using adequate stimulation. Investigations should alsoconsider whether acupuncture may lead to a reduction of nicotine withdrawal symptoms.

    Study Reason for exclusion

    Boureau, 1978

    This study compared 2 groups who both received identical acupuncture following aninjection: one group were injected with saline, the other with naloxone. Therefore, 2

    hypotheses are tested simultaneously: does acupuncure help smoking cessation byreleasing endogenous opioid peptides?
