Pregnenolone as a Treatment for Cannabis Intoxication

The present study will characterize the ability of pregnenolone to reverse the acute intoxication and associated symptoms of cannabis. Healthy adults with a history of cannabis use will be recruited to participate in a placebo-controlled, within-subject crossover study at Johns Hopkins Behavioral Pharmacology Research Unit (BPRU). By clarifying the ability of pregnenolone to reverse cannabis intoxication symptoms, this study will pave the way for larger clinical studies that provide a foundation for the development of future CB1-receptor NAM medications that could be applied in emergency situations and potentially validate pregnenolone as a treatment for cannabis intoxication.
