just leave it as is. if you want it, you can easily get a hold of it. by leagalizing it, users would just have to pay taxes on it, and, as said above, the quality would go down.
idk about you guys, but around here i walk into a deli, theres a good chance somebody is out front smoking. you walk down the block, theres a good chance somebody is sitting on the porch smoking. your at the beach in the summer, theres a good chance theres somebody smoking it. its easy to get, so i dont see why people make a fuss about legalizing it. 90% of the time a cop catches someobdy with it, the cop will just take it. wont write them a summons or anything. fact of the matter is, people are just used to it, and little is being done to stop the use of it.
