no fuckin way. walt is providing a chemicaly safe METH..
There's a world of difference between chemically pure and chemically safe. Once you remove the impurities you're still left with the effects of the drug itself. And since it's not sold in unit-dose quantities every hit is a guess as to dosage - guess wrong and you're up for a couple days of sweaty paranoia just like with trailer-park meth. And you're still dealing with sketchy, dangerous people every time you cop.
Cannabis, now that's chemically safe.
