Weed is better off illegal but make it only an infraction to possess and a misdemeanor to grow.
I say that only because I love weed and dont want the govt ****ing it up with taxes regulations and a bunch of BS.
Plus legalizing kills the value so it would actually hurt the economy. I heard colo plan was to tax it locally for sales tax, but then also add a 50 an ounce excise tax? That would keep price high but also still leave plenty of incentive to grow and sell outside the tax. So now you still need to enforce and you don't save the money you thought you were going to. Hell they start a tax they will probably put more resources into stopping home growers and growers skirting the tax.
