Progesterone for Cannabis Withdrawal

Completed · Early Phase 1 · Has a placebo group

Conditions studied: Cannabis Use Disorder, Cannabis Withdrawal

In brief

Sex and gender differences in behavioral, biological, and clinical correlates of substance use disorders are myriad, yet there exists a dearth of gender-informed treatment options. Ovarian hormones have been identified as potential mechanisms of these disparities , and recent clinical trials have begun to examine their utility as possible pharmacotherapeutic agents. The ovarian hormone progesterone has shown promise as a treatment for female cocaine and nicotine users, but has not yet been tested for cannabis. Gender differences in cannabis withdrawal, which is associated with relapse, are pronounced and several studies report more severe and impairing withdrawal symptoms in women compared to men. Developing pharmacological interventions for cannabis withdrawal remains an important priority given the significant cognitive, psychiatric, and physical consequences of heavy cannabis use.
