The History of Medicinal Cannabis
Background
As early as 2737 B.C., the mystical Emperor Shen Neng of China was prescribing
marijuana tea for the treatment of gout, rheumatism, malaria and, oddly enough, poor
memory. The drug's popularity as a medicine spread throughout Asia, the Middle East
and down the eastern coast of Africa, and certain Hindu sects in India used marijuana
for religious purposes and stress relief. Ancient physicians prescribed marijuana for
everything from pain relief to earache to childbirth.
In terms of American history, it was reported that in 1492 Christopher Columbus
brought cannabis as rope of hemp into the New World. In 1619, Jamestown colony law
declared that all settlers were required to grow cannabis. George Washington grew
cannabis for fiber production at Mount Vernon as his primary crop.
By the late 18th century, early editions of American medical journals showed
recommendations of hemp seeds and roots for the treatment of inflamed skin,
incontinence and venereal disease. Irish doctor William O'Shaughnessy first
popularized marijuana's medical use in England and America. As a physician with the
British East India Company, he found marijuana eased the pain of rheumatism and was
helpful against discomfort and nausea in cases of rabies, cholera and tetanus.
The change in American attitudes toward marijuana came at the end of
the 19th century, when between 2% and 5% of the U.S. population was
unknowingly addicted to morphine, a popular secret ingredient in patent
medicines. To prevent more of the country from morphine addiction, the
government introduced the Pure Food and Drug Act in 1906, creating the
Food and Drug Administration. While it didn't apply to marijuana and
merely brought the distribution of opium and morphine under a doctors'
control, the regulation of chemical substances was a major shift in
American drug policy.
It wasn't until 1914 that drug use was defined as a crime, under the Harrison Act. To
get around states' rights issues, the act used a tax to regulate opium- and coca-derived
drugs; it levied a tax on nonmedical uses of the drugs that was much higher than the
cost of the drugs themselves, and punished anyone using the drugs without paying the
tax. The Marijuana Tax Act of 1937 made possession or transfer of cannabis illegal
throughout the United States under federal law, excluding medical and industrial uses,
in which an expensive excise tax was required. Annual fees for the tax were $24 for
importers, manufacturers, and cultivators of cannabis, $1 annually for medical and
research purposes, and $3 annually for industrial uses. Detailed cannabis sale logs were
required to keep record of cannabis sales. Cannabis could be sold to any person who
has previously paid the tax at $1 per ounce or fraction thereof; however, it was $100
