Drug info - Injecting base amphetamine

[Dexyfiend]

Hi all, Swim was just wondering if the injection of base amphetamine is a particulary wise thing to do?
He asks because at present methamphetamine (which is ideal to inject as is it water soluble) is difficult to attain.
He realizes that base amphetamine is unstable and may want to combine in his blood to make something else entirely. Swim has done it on a number of occasions and reported no ill effects but figures just because he's fine dosent mean it's a smart thing to do.
Swim thinks that a sythesis to amphetamine sulphate may be the answer...

Thoughts from any swiy's... thanks
