Unfortunately prices are against the rules I guess. It varies massively depending where you're at. In the Northeast a gram can cost four times as much as in the south for comparable quality. In the southwest, near the mexican port of entry, it's dirt cheap and of very high quality. Mexican cartels have begun cooking in superlabs south of the border and their product is so good it has put a lot of domestic cooks out of business.
I just got back from San Diego, which is right next to the border. Meth is the drug of choice among junkies there, meth is so cheap, pure, and the high lasts so long that even the homeless can afford a serious habit. You can get a gram for the same price of an eighth of good weed. A gram can last you for days, easily.
