You have to never live near it not to experience how things like how meth and heroin kills a neighborhood, turn them into full fledged ghettos and empowers gangs.

That's a direct result of making those drugs illegal. If they were legal, how could their use affect neighborhoods or empower gangs?

It's important to remember that ALL drugs, even heroin and cocaine, were completely legal and freely used before 1914. We seemed to survive OK until then.
