In 2001, Nova Scotian Rick Simpson discovered that a cancerous spot on his skin disappeared within a few days of applying an essential oil made from marijuana. Since then, Simpson and others have treated thousands of cancer patients with incredible success. Researchers in Spain have confirmed that THC, an active compound in marijuana, kills brain-tumor cells in human subjects and shows promise with breast, pancreatic and liver tumors. The U.S. Food and Drug Administration, however, classifies marijuana as a Schedule I drug, meaning that it has no accepted medical use, unlike Schedule II drugs, like cocaine and methamphetamine, which may provide medical benefits.
