Ooooooh my!!!! This question brings up terrible memories!
Before crystal methamphetamine(otherwise known as "Ice, Shard, Crack(it pisses me off too, just ignore it), Shabs/Shabu, etc" In Australia) became prominent a few years ago, and almost overnight mind you, any Aussie will confirm this. We used to get this stuff that is in the most common slang, "Speed" but in each circle/city/state they had different names for it, ours were "goey", "base" and "gas"
which took me years to figure out why "gas" but I eventually figured out I think its either a reference to a step in the synthesis that I wont mention or its like gas you put in a car, it makes you go go go.
Anyway the amount of different forms you could get this stuff I was endless. We usually got a white to yellow paste and the taste and smell of this stuff, well the thought of it makes me want to throw up. It was absolutely foul, but people said they somehow liked it. You get rocks sometimes of various colours(pink, brown, yellow, white) that were smokeable and they became available much more just before the crystal invasion........ Then, almost over night, every single speed dealer began selling ice and the locals took to it like a pig to mud. At least I don't have to hold my breath when I have a shot because that speed gave such a strong taste in the mouth if I didn't hold my breath id likely throw up lol
