You would have to be careful, a lot of the illegal drugs are illegal for a reason. We have enough of a problem with alcohol, if drugs got legal we would start "binge taking" them aswell and all would be bad.
At the moment lots of people take them but to avoid getting caught they don't go out in public when they do. So I think keeping the laws at least stop un-ruely behaviour, again like the problem with alcohol.
So yea, I'm not against some
drugs, maybe just making the laws a bit more loose so we can get them into the country easier
