Yes, in these United States, as in many other countries, the government picks and chooses what it deems unacceptable for consumption by fully grown adults. Alcohol, a drug proven to be dangerous and deadly if misused, is OK. So is oxycontin, if legally prescribed by a doctor or if right-wing talk-show hosts use it. Tobacco, whose packages are covered in health warnings, is A-OK, except in many public places. But a plant many studies show to be no more (and often less) harmful than booze and cigarettes is verboten for almost anyone at any time under law.
Why can’t Americans use marijuana — a plant that grows out of God’s green earth — for any damn thing they want, and especially for medicinal purposes? Beats me, friend. All I can point to is the nation’s absurd, inexplicable, and cruel War on (Some) Drugs and a Plant and offer the obvious as a reply: Because Uncle Sam says no. Period.
