What are the specific differences between amphetamine sulphate, base amphetamine -the paste, and methamphetamine crystals?
Are there specific chemical differences? And just how much difference is there in strength? I think base amphetamine is something more used over here in the U.K. as ice is in the U.S. I know base is chemically related structurally to crack, cut just how much?

For a variety of reasons, essentially all amphetamine synthesized in the United States (and in Asia and Mexico and South America destined for the US illegal market) is methamphetamine hydrochloride.
