legalization, decriminalization, bans, etc...it's all very complex. Nearly everyone these days has lost a friend, neighbor, co-worker, or loved one due to addiction. In an ideal world, bans would work. In reality, they just create thriving black markets. I don't know the solution for these issues, but it's a lot harder than we often make it seem. Throw in that legalization of substances helps validate their existence, yet society would clearly be better off without them.
