Derek Thompson follows the logic of regulating and taxing tobacco rather than banning it:
The government's effort to manage tobacco rather than make it illegal is exactly what belongs in the debate over pot and other illegal substances that could, at the very least, provide significant boons to medical pharmacology. The FDA has rejected the possibility of making cigarettes illegal by saying the underground product would be "even more dangerous than those currently marketed." So when you make popular products illegal, it has the potential to make those products more dangerous. Gee, ya think?
I know that Gee, ya think is about as far as you can get from a comprehensive plan for the controlled legalization of marijuana and other substances. But let's be adults here. Obama understands the limits of cigarette law because he understands the market for cigarettes. Maybe what the drug debate really needs is a joint in the West Wing.
