“The U.S. government’s “official expert” on cannabis from 1938 to 1962 once testified in court, under oath, that he had smoked cannabis and it turned him into a bat. Just think about that for a moment.”
The U.S. government’s “official expert” on cannabis from 1938 to 1962 was Dr. James Munch, a professor of physiology and pharmacology in the School of Pharmacology at Temple University in Philadelphia, PA.
That was the scene in early 1938 when a defense attorney called upon Dr. Munch, the expert witness who had testified for the Federal Bureau of Narcotics during the Marihuana Tax Act Hearings, to speak on his client’s behalf. It was during this trial that Dr. Munch “admitted” that he had experimented with marijuana on dogs and had—for purely scientific reasons—tried the drug himself. When he was asked how marijuana affected him, Dr. Munch famously replied, still under oath, mind you, “After two puffs on a marijuana cigarette, I was turned into a bat.” According to Booth, Dr. Munch went on to state, “he flew around the room and down a 200-foot-deep inkwell.”
