Maybe it will, maybe it won't.
It's too bad someone hasn't come up with the idea of dividing a country into separate sub-jurisdictions so we could test different approaches to things like drug use, and the jurisdictions with the best approaches would gradually see those adopted across the board. Rather than dictating policy for the entire country without any sense of whether or not it is working.

Actually, that is an idea in progress. 4 years ago even the leftist libtards in California realized legal marijuana was a bad idea and so that proposition was defeated. Now that Colorado and Washington have allowed it - we will witness the free-fall of civil society in those states as crime and welfare rates increase.
