Interpreting the Facts: The Underground Market for Illegal Drugs

Still true:

The Soviet government censors the press; hence, the Russians have a samizdat (underground) press — which American presidents interpret as proof of the spiritual invincibility of the free market. The American government censors “substances” (drugs); hence, the Americans have a samizdat (underground) pharmacopoeia — which American presidents interpret as proof of the subversion of the free market by greedy “drug lords” and hostile foreign governments.
