Well, which method do you prefer? I know you have smoked (only a foil, not a glass pipe), snorted, & ate meth/tweak/crank whatever you wanna call it. Its just a matter of what kind of buzz you are looking for. Smoking it by far gets the quickest and strongest buzz out of the 3 methods I mentioned above, to most people. But people are different, so just try em all. Eating it is a slow onset, long duration, but not an intense speed. Snorting it is snorting it. And smoking it is usually king to most people.
So advice from a friend/enemy - try smoking it out of a glass pipe.. Its much, much better than a foil.
Just some of my $.02 since I have seen you "experience" this drug. Don't take this wrong, just some advice.
