On March 13, 2025, CReDO Science presented, “History of Cannabis Prohibition and Scheduling,” an hour-long webinar detailing the history of cannabis policies, from historical texts to modern day prohibitions. Ethan Russo, MD, neurologist and medical researcher, explained significant dates, current cannabis scheduling, and the potential for the future.
In his explanation of the history of cannabis prohibition, Dr. Russo noted some important documents that he argues contain references to cannabis policies, namely the Bible, the Talmud, Egyptian laws, and a papal bull in 1484. He also noted a 3200-page study on the Indian Hemp Drugs Commission from the late 1800s, which advised against its prohibition and encouraged medical and religious use.
