Introduction: The opioid crisis, a declared national health emergency, has prompted the exploration of innovative treatments to address the pervasive issues of opioid cravings and associated depression. Aims: This pilot cohort study investigated the efficacy of transcranial Photobiomodulation (tPBM) therapy using the SunPowerLED helmet to alleviate these symptoms in individuals undergoing treatment for opioid addiction at a rehabilitation center in West Virginia. Methods: Employing a quasi-experimental design, this study enrolled participants into two groups: one receiving tPBM therapy alongside standard care and a control group receiving standard care alone. The helmet features include the following: total wavelength = 810 nm, total irradiance = 0.06 W/cm 2 (60 m W/cm 2 ), and total fluence = 172.8J/cm 2 . Results: The results of the Wilcoxon signed-rank tests for within-group analysis and Mann-Whitney U tests for between-group comparisons revealed statistically significant reductions in the intensity (W = 7.36 , p = 0.012), time (W = 6.50, p = 0.015), frequency (W = 6.50, p = 0.010), and total scores of opioid cravings (W = 7.50, p = 0.009), as well as improvements in depression symptoms (W= 8.00, p = 0.005) within the PBM group compared to the non-PBM group. Discussion: These findings suggest that transcranial PBM therapy could be a promising noninvasive intervention for reducing opioid cravings and depressive symptoms in individuals with opioid use disorder, warranting further investigation through larger randomized controlled trials.
