Eventually, yes; but I also think prudence dictates that we start by relegalizing marijuana and see what we learn from that.
No, prudence dictates we maintain the status quo, lacking a compelling reason to change.
I haven't seen a compelling reason to change from you or anyone else on this board as to why marijuana (not crack cocaine, not all drugs, not those drug less harmful than alcohol, not "soft" drugs), marijuana should be made legal.
If your argument were "marijuana would replace alcohol, 1:1", I would call that a compelling argument. "Marijuana cures cancer", I would call a compelling argument.
"Because, dude" is not a compelling argument.
Your arguments are generic. It costs money. It interferes with freedom. It's unconstitutional. The WOD is intrusive.
Those are good arguments for the legalization of all drugs. I'm not at all interested in debating the legalization of all drugs. What is your argument for the legalization of just marijuana?
