Congress passes the marijuana tax act

The Marijuana Tax Act, passed by Congress in 1937, effectively criminalizes marijuana by restricting possession of the drug to individuals who had paid a tax and had been authorized to use it for medical and industrial uses. The act was overturned in 1969 and repealed by Congress a year later.
