I know it's big in certain parts of Eastern Europe, and has small circles of users in the gay scene in some major European cities (namely London), but otherwise I'm fairly sure you're right.
And I have no idea why, it seems insane to me that someone would choose dirty, jittery racemic amphetamine sulphate over clean, smooth crystalline d-methamphetamine. It literally baffles me.
This is what I find surprising in Australia. Amphetamine sulphate is more expensive than meth per point when it is so much weaker and usually dirtier.
