I see certain substances as being the same as alcohol. If you legalize them, you can at least regulate them and increase their qualities. By qualities, I mean their harmful effects on the users. By regulation, I mean you can make people pay for abusing them, like alcohol.
Making something illegal will only drive it underground. I thought the government learned this lesson the hard way during prohibition. Well, I guess people aren't as smart as my younger self hoped.
