How Marijuana Became Legal

Rosenfeld smokes the marijuana to relieve chronic pain and muscle spasms caused by a rare bone disease. When he was 10, doctors discovered that his skeleton was riddled with more than 200 tumors, due to a condition known as multiple congenital cartilaginous exostosis. Despite seven operations, he still lives with scores of tumors in his bones.
Rosenfeld is one of four people in the United States whom the federal government supplies with medical marijuana. Each is a living anomaly because, officially, the U.S. Drug Enforcement Administration, NIDA, and the FDA all take the position that marijuana has "no currently accepted medical use."
That's the only way federal law can continue to classify marijuana, like heroin, as a "Schedule I controlled substance," forbidden from being prescribed by doctors. (Numerous dangerous, psychoactive, and addictive opium derivatives, by contrast, are more leniently classified as Schedule II drugs, allowing prescription use.)
Over the years the government's position has become progressively more embattled, if not untenable.
