To Treat Urinary Infections
Until the Marihuana Tax Act of 1937, marijuana served as a catch-all remedy for a variety of ailments. A medication that could be used as a remedy for insomnia might also (supposedly) cure urinary infections.
Advertisers said that most popular tinctures of the early 20th century cured urinary infections or urinary tract pain. People also used them to treat sexually transmitted diseases. Largely due to the Marihuana Tax Act, and following legislation that prevented research on marijuana, we still don’t know which cannabinoids are useful for which conditions.
