In most countries it's considered a medical issue. In most countries you don't have politicians getting up screaming about how tough they're going to be on drugs. So the first thing we've got to do is move out of the phase of population control, and into the sphere of social issues. The Rand Corporation estimates that if you compare the effect of criminal programs versus educational programs at reducing drug use, educational programs are way ahead by about a factor of seven. Educational programs aren't the only category.
Education also has to do with the social circumstances in which drugs are used.
The answer to that is not throwing people in jail. It wasn't that there was an educational program that said to stop drinking coffee, it's just that attitudes toward oneself and towards health, how we live and so on, changed among the more educated sectors of the population, and these things went down. And none of it had to do with criminalization. It just had to do with a rise in the cultural and educational level, which led to more care for oneself.
