Governments do a lot of silly and sometimes heinous things. The American War on Drugs is both: it is silly, and it is heinous. The economic case for drug legalization is rock-solid and straightforward, and a lot of the maladies and social ills that we associate with drug use are products not of the drugs themselves but of the fact that they are illegal. You don’t see many criminal enterprises trafficking in coffee and tea (my drugs of choice) precisely because they are legal. If caffeine were banned, I’m certain that it would appear on the underground market, probably in an injectable form.
