A randomized controlled trial of auricular acupuncture for cocaine dependence

FRANÇAIS :
Quatre vingt deux cocaïnomanes en traitement de maintenance à la méthadone ont été assignés au hasard soit à des séances d'acupuncture auriculaire, soit à des séances d'acupunture sur des zones non actives, soit à des séances de relaxation sans acupuncture, à raison de 5 séances par semaine, pendant 8 semaines. Le contrôle de la consommation de cocaïne est effectué par dépistage urinaire 3 fois par semaine. Les patients traités par acupuncture sont plus susceptibles d'avoir des dépistages urinaires négatifs que les autres patients.

Background: Partly because of a lack of a conventional, effective treatment for cocaine addiction, auricular acupuncture is used to treat this disorder in numerous drug treatment facilities across the country for both primary cocaine-dependent and opiate-dependent populations. Objective: To evaluate the effectiveness of auricular acupuncture for the treatment of cocaine addiction. Methods: Eighty-two cocaine-dependent, methadone- maintained patients were randomly assigned to 1 of 3 conditions: auricular acupuncture, a needle-insertion control condition, or a no-needle relaxation control. Treatment sessions were provided 5 times weekly for 8 weeks. The primary outcome was cocaine use assessed by 3-times-weekly urine toxicology screens. Results: Longitudinal analysis of the urine data for the intent-to-treat sample showed that patients assigned to acupuncture were significantly more likely to provide cocaine-negative urine samples relative to both the relaxation control (odds ratio, 3,41; 95% confidence interval, 1.33-8.72; P=.01) and the needle-insertion control (odds ratio, 2.40; 95% confidence interval, 1.00-5-75; P=.05). Conclusions: Findings from the current study suggest that acupuncture shows promise for the treatment of cocaine dependence. Further investigation of this treatment modality appears to be warranted.
