It was 1920 when smoking began to catch on in the United States. Its recreational use was restricted to jazz musicians and people in show business. "Reefer songs" became the rage of the jazz world. Marijuana clubs, called tea pads, appeared in every major city across the country. Authorities tolerated these establishments because it was not illegal or considered a social threat. In the early 1930's marijuana became stereotyped as a violent drug, and by 1936 was illegal in all states. Marijuana research was at a stand still and the thought of it being a violent drug faded and the idea that it was a gateway drug emerged in the late 1940's early 1950's. In the 1960's marijuana became very popular among the young college crowd. This was looked at as a challenge to authority and the government.
The effects of marijuana are minimal. The high has a feeling of euphoria, peacefulness and well-being. Tetrahydrocannabinol (THC) is the active chemical in marijuana. It's estimated that a person would have to ingest a dose 20,000 to 40,000 times the average dose before death would occur. In the early 1990's sophisticated research on marijuana began. The scientists discovered THC stimulates special receptors in the brain. Researchers have now isolated a natural substance that appears to produce the same effects as THC
