Cannabis grew in North America during prehistoric times perhaps brought here by early explorers and migrating birds. The Ancient Mound Builders’ archeological finds yielded evidence of clay pipes containing hemp wrapped in hemp cloth dating from about 400 B.C.
Marijuana seeds were brought to America from England in 1632 by the Pilgrims. By 1762, Virginia farmers were penalized for not growing this plant, as it was such an important useful and economic crop. George Washington grew it at Mount Vernon in 1765. He also pulled up the male plants which increases the potency of psychoactive female plants. Thomas Jefferson advised its cultivation. In 1850, marijuana was America’s third largest crop. Between 1840 and 1900 over a hundred published papers recommended Marijuana as medicine. The resin is most concentrated on the flowering tops of the female plants. Marijuana buds and leaves are smoked. Marijuana is not soluble in water as a tea, though is sometimes eaten in foods, though must be cooked in some type of oil for 15 minutes. Tincture of cannabis is used medicinally, though less psychoactive. Hashish is marijuana resin mixed with fat and honey and compressed into cakes.
