Acupuncture, hypnotherapy, and aversive smoking are the most frequently studied alternative smoking cessation aids. These aids are often used as alternatives to pharmacotherapies for smoking cessation; however, their efficacy is unclear.
We carried out a random effect meta-analysis of randomized controlled trials to determine the efficacy of alternative smoking cessation aids. We systematically searched the Cochrane Library, EMBASE, Medline, and PsycINFO databases through December 2010. We only included trials that reported cessation outcomes as point prevalence or continuous abstinence at 6 or 12 months.
Fourteen trials were identified; 6 investigated acupuncture (823 patients); 4 investigated hypnotherapy (273 patients); and 4 investigated aversive smoking (99 patients). The estimated mean treatment effects were acupuncture (odds ratio [OR], 3.53; 95% confidence interval [CI], 1.03-12.07), hypnotherapy (OR, 4.55; 95% CI, 0.98-21.01), and aversive smoking (OR, 4.26; 95% CI, 1.26-14.38).
Our results suggest that acupuncture and hypnotherapy may help smokers quit. Aversive smoking also may help smokers quit; however, there are no recent trials investigating this intervention. More evidence is needed to determine whether alternative interventions are as efficacious as pharmacotherapies.

    ABSTRACT: Answer questions and earn CME/CNE Hypnosis has been used to provide psychological and physical comfort to individuals diagnosed with cancer for nearly 200 years. The goals of this review are: 1) to describe hypnosis and its components and to dispel misconceptions; 2) to provide an overview of hypnosis as a cancer prevention and control technique (covering its use in weight management, smoking cessation, as an adjunct to diagnostic and treatment procedures, survivorship, and metastatic disease); and 3) to discuss future research directions. Overall, the literature supports the benefits of hypnosis for improving quality of life during the course of cancer and its treatment. However, a great deal more work needs to be done to explore the use of hypnosis in survivorship, to understand the mediators and moderators of hypnosis interventions, and to develop effective dissemination strategies.

    ABSTRACT: Rationale Cue reactivity is a key factor in modulating motivational and goal-directed behaviors associated with compulsive drug intake and relapse. Smoking-associated cues produce smoking urges and cravings and are accompanied by the activation of brain regions involved in attention, motivation, and reward. Objectives We investigated whether acupuncture ameliorates cravings induced by smoking-related visual cues, and we explored the neural mechanisms underlying the effects of acupuncture on modulating smoking urges. Methods After 36 h of smoking abstinence, 25 right-handed male smokers underwent fMRI, during which smoking-related and neutral visual cues were presented. Twelve subjects were treated with real acupuncture (RA) at HT7 and 13 subjects received sham acupuncture (SA). During the scanning sessions, craving scores to smoking-related visual cues were assessed before and after RA or SA treatment. The differences in brain responses to smoking vs. neutral cues after treatment between the RA and SA groups were detected using three-way ANOVAs (Cue × Session × Group). Results After treatment, the craving scores were significantly decreased in the RA group, as compared to the SA group. When we explored the neural substrates of acupuncture on the modulation of cravings induced by smoking cues, significant differences were found in the medial prefrontal cortex, the premotor cortex, the amygdala, the hippocampus, and the thalamus. Conclusions These findings suggest that acupuncture alleviates cue-induced cravings through the regulation of activity in brain regions involved in attention, motivation, and reward relative to craving scores in the initial abstinence phase.
