NCT03729869

Brief Summary

This is a research study to find out if a hormone called progesterone affects marijuana users' stress response and marijuana use. Progesterone is a naturally occurring sex hormone involved in the menstrual cycle and reproduction, and has been shown to reduce withdrawal symptoms when people stop using substances like cocaine and nicotine. It is not FDA approved for treating cannabis users and is considered an investigational drug in this study.
