Is "base speed" methamphetamine?

[Zany]

the only speed ive ever had was a white powder, but ive heard of stuff called base which is apparently like a yellow paste or something... and its supposed to be well strong... is this methamphetamine and if not what form of amphetamine exactly is "base" and the powdered "speed"

[Micklemouse]

'Base' and powdered speed are both amphetamine sulphate, not methamphetamine. Base is indeed pretty damn strong (allegedly!), being as near to pure, uncut speed as you'll get this side of the pond - tastes like a nappy, but will keep SwiZ up and buzzing seemingly for ever!

To avoid self-incrimination, try to avoid the use of 'I' when posting about potentially illegal acts - many people here use SwiM (Someone who isn't Me), or variations of (e.g. SwiZ = Someone who isn't Zany), to get around this, but a bit of imagination in this is always appreciated!
