What Researchers Studied About This Condition and Cannabis

Many people believe cannabis isn't addictive, but research tells a different story. Cannabis withdrawal is a well-characterized phenomenon that can make it difficult to stop using.

This 2022 review in Addiction examines the diagnosis, prevalence, and management of cannabis withdrawal—providing essential information for patients and clinicians.

Understanding withdrawal helps patients prepare if they plan to stop or reduce cannabis use.

How This Systematic Review Was Conducted

Researchers conducted a narrative review of the literature on cannabis withdrawal:

• Examined diagnostic criteria and symptom presentation • Reviewed prevalence in different populations • Assessed time course of withdrawal symptoms • Evaluated management strategies and medications • Identified research gaps and clinical implications
