The smuggling of narcotics in the U.S had increased during this time due to the Great Depression and war. In 1937 Congress passed and enacted the Marijuana Tax Act which criminalized the plant; moving forward into the late 50’s stricter laws and sentencing laws set mandatory minimum sentences for drug-related crimes. As time passed the use of Marijuana by mainstream Caucasian Americans help garner the CDAPCA (Comprehensive Drug Abuse Prevention and Control Act) of 1970 which in short categorized Marijuana separately from other narcotics. However in 1986 POTUS Regan signed the ADAA(Anti-Drug Abuse Act) reinstating mandatory fines and upping the federal penalties for possession and distribution still making illegal to posses.
Since then the great state of California enacted Proposition 215 which would legalize medical marijuana use for people with chronic illnesses and diseases. 80+ years ahead and now more that half of the states have now decriminalized and or passed legislation for medical/recreational use. Regulation by the government and propaganda by the U.S has kept a plant with multiple healing and useful agents from being used because it was though to cause hysteria, hallucinations, manslaughter ect. is actually in turn more beneficial.
