Objective: Recent research suggests potential therapeutic benefits of cannabis-derived products, a lower risk profile than other illicit substances, and significant functional improvement from reduced use. Likewise, low abstinence rates and low motivation to achieve abstinence among those with cannabis use disorder (CUD) are the norm. As such, the harm reduction model has gained traction among substance use scientists and health care professionals as a viable alternative approach. Yet, to date no formal definition of cannabis harm reduction has been proposed.
Method: We reviewed the literature, including two recent empirical papers published in the Psychology of Addictive Behaviors, Sherman et al. (2022) and Borodovsky et al. (2022), which demonstrate that harm reduction is sufficient to achieve functional improvement. We then propose and define a harm reduction approach for cannabis use research and treatment, and argue why this approach is a timely, necessary discussion.
Results: We suggest that a cannabis harm reduction approach includes treatment, research, and education initiatives that reduce the public health burden of cannabis use. This approach includes interventions that reduce functional impairment and risk from cannabis, reduced or managed use, and sometimes, but not necessarily, abstinence. Psychoeducation for treatment providers, legislative barriers, and research recommendations are also discussed.
Conclusions: Research and treatment for CUD has historically focused on cannabis abstinence. Treatment trials rarely yield durable abstinence rates, and reduction has recently been tied to functional improvement. We comment on Sherman et al. (2022) and Borodovsky et al. (2022) and propose a shift toward a cannabis harm reduction approach. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
