Quote from: bynter on November 12, 2012, 11:27 pmSorry for the poor wording. I was referring more to, "if i'm used to 30mg adderall, how much meth would be equivalent to that?"and considering how similar the mechanisms of action and molecular structures are, I find it really hard to believe there isnt a cross tolerance.Oh, I think it is actually called cross tolerance. I just meant I find that term misleading. It's not like some of it carries over: most or all of it carries over is all I meant.If you have a mg scale, the same amount of meth as you would take adderall. Swallow it. Anything else is too much of a peak and not sustained enough for really getting stuff done, IMO. Besides, if you have to stop what you're doing every 30-90 minutes just to vape some more shit, it really gets in the way, ya know.My reasons for just measure them equal: a 30mg adderall has about 22.5mg biologically useable amphetamine salts. Illicit meth isn't pure. How much is it cut? I can't say, but DEA reports suggest it's 30-70% pure. I think some of the better vendors are definitely toward that top end there, maybe even better. So about equal useable amphetamines per mg.
