Who knows. But that’s life with a legal product, you never know when the fed is going to go stupid. But even then you wind up with a black market like the untax stamped cig market, which isn’t nearly as violent as the current pot black market.
I doubt there will be more use. With it legal and regulated it actually gets harder for various classes to get than with it illegal. It’s a lot easier now for a teen to get pot than beer, because people selling beer have liquor licenses they wish to protect, and people selling are already breaking the law and don’t really care.
It’s really all about picking your poison. People that are going to smoke pot are going to smoke pot, the questions you need to ask yourself is would you rather the money go to Mexican drug cartels or the neighborhood liquor stores; and would you rather the seller have some sort of rules to follow or do whatever they want.
Sometimes I think the best solution to the war on drugs is to give the druggies whatever they want, as much as they want, at nominal cost and let Darwin take care of them.
For harder drugs, I also think the draconian solution they have in Singapore also has more appeal than the present status quo.
