Perhaps you have to take a test designed to measure self control before being allowed access to addictive drugs?

I think many of these dangers would be much smaller if we had a better educated public when it comes to the differences and specific dangers of particular drugs. I think legalization would increase awareness in this area, but I agree I am not convinced it would be enough for everyone.

Funny though that all of your comparisons are legal. We don't outlaw fast food because some people eat it to obesity. We don't outlaw credit cards because some people use them to drive themselves into unworkable debt.
