Where is 1% of the American adult population?

Drug crimes include both possession and distribution, so it's hard to tell how many may be "victimless".

If they're restricted to either possession or distribution? All of them.

As George Carlin memorably opined about prostitution, which works on identical logic: "Selling is legal. F#*$ing is legal. So why isn't selling f#$*ing legal?"

If there's violence, or border crimes, or whatever else involved, then that's a different offence - notably, one that wouldn't be necessary if they just legalized drugs.
