This is the sanest thing he's ever said.
Personally, I would love to see all drugs legalized. Not medicinal, no age-limits, no restrictions.... total free for all.
(OK.... maybe age limits - because kids are stupid, and have no accountability)
There would be a transitional period, and some unfortunate collateral damage, but it wouldn't take a great deal of time before balance is restored as all the tweakers, nodders, speedfreaks, crackheads and other various and sundry junkies will very quickly remove themselves from the gene pool, by either overdosing, or darwining themselves out of existing in a drug-induced fugue.
Thereby, leaving the rest of us (those of us with enough goddamn sense to not ingest poison) in peace.
Some of you may die.
But that's a sacrifice I'm willing to make!
