Positive Effects of Laser Acupuncture in Methamphetamine Users Undergoing Group Cognitive Behavioral Therapy: A Pilot Study

BACKGROUND: Methamphetamine (MA) addiction has become a crucial public health concern because of its adverse consequences to individuals and the society. OBJECTIVE: To investigate the clinical efficacy of laser acupuncture combined with group cognitive behavioral therapy for MA addiction treatment. MATERIALS AND METHODS: MA users who participated in group cognitive behavioral therapy and met the inclusion criteria were referred from psychiatrists to participate. The participants received laser acupuncture treatment once a week for 2 months (total eight treatments) on selected acupoints (PC6, HT7, LI4, ST36, SP6, and LR3). Laboratory assessment included urinalysis for MA and liver function tests aspartate aminotransferase, alanine aminotransferase, and γ-glutamyltransferase (AST, ALT, and γ-GT), whereas the objective assessment included visual analog scale (VAS) for MA craving and refusal and Pittsburgh sleep quality index (PSQI), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI) questionnaires. All data were collected before and at 1 and 2 months after treatment. Cognitive behavioral therapy completion rate and rate of relapse to MA use were also determined. RESULT: Fifteen participants were enrolled, of whom seven completed the trial. Urinalysis for MA revealed a decrease in drug use from 57.1% to 28.6%. Compared with those before treatment, PSQI scores were significantly lower at 1 and 2 months after treatment (−3.73 and −4.10, respectively; both p < 0.001), and so were BDI scores (−5.64 and −8.17, respectively; p=0.01 and 0.001, respectively). However, no significant difference was observed in the liver function test, VAS of craving and refusal, and BAI results. A slight improvement in the motivation for drug abstinence and anxiety was observed during the treatment course. Participants reported no adverse events. CONCLUSION: Laser acupuncture combined with group cognitive behavioral therapy may improve sleep quality, alleviate depression, and reduce MA use. Additional large-scale studies confirming the effectiveness of this modality are warranted.
