Doesn't Amsterdam give out a monthly ration of Heroin and also have designated "use" areas around town with a fresh supply of clean needles? Their crime rate is much, much lower than the U.S.'s.
If you think people aren't driving under the influence of drugs right now then you are seriously mistaken. I know people that drive under the influence of alcohol, pot, acid, shrooms, coke, meth...etc. It's something that cannot be avoided wheter drugs are legal or illegal.
