This is casino gambling gone horticultural. When the cash-starved States get a whiff of what WA and CO are pulling in from legal marijuana, they’ll be lining up to be next. I know a lot of addle-brained Prohibitionists are crying in their beers over this (the irony!), but that just makes it so much more fun.
Pot is weird stuff that can have dramatic affects on some peoples thought processes and memory. The very mention of the word can make liberals suddenly remember the 10th Amendment, and a lot of self-described conservatives suddenly forget it.
