Its about time because they are starting to realize that instead of wasting money trying to stop all the illegal drug use, that they can legally sell the drugs to make money. The government only made marijuana illegal because we don't grow the majority of it. They want us hooked on drugs made here, not somewhere else
They won't be stopping anything.
by 'legal for medical uses' that only counts to a certain amount of weed and with a prescription, they'll still be coming down on people for carrying weed without or with too much.
Also I think it's ridiculous to think that the only reason that marijuana is illegal in large amounts is because it's grown in Columbia. Consider that people who use drugs go for stronger and stronger drugs over time, and then, well, I dunno, fuck around and kill or injure people, or cause issues in public.
Alcohol is addicting and it wasn't made illegal back in the day because Americans didn't make it, it was made illegal because people fucked up other people's lives with the stuff (granted that didn't last long, but that's not the point).
