British Columbia decriminalized all drugs recently. I think it's too early to see if it makes any difference. Their theory is that if someone is Od'ing and everyone has a small amount of drugs people won't call for help because they're afraid they will go to jail. This allows users to to call for help without thinking they are going to get in trouble. I'm pretty sure the cops won't even take their drugs there.

Next up we need to have free drug testing for users so they know what they are taking is what they think they are taking. Most deaths are from bad drugs.
