be aware that speed fucks up your brain, liver, kidneys and, if u smoke it, your lungs too. i dont think the health effects of smoking methamphetamine have really been studied very much yet. but i would imagine both the drug and whatever else may be in it would do some bad things to your lungs.
its also alot more addictive that way, cos u get the instant rush. makes you crave it in ways that are really just not cricket. its one fucking nasty drug and its best avoided completely if you cant use it in extreme moderation.
i quit smoking meth, because i knew that it was something i would really really regret doing one day... its just plain nasty!!!
of course i cant deny that its very enjoyable to hit the old crack pipe with your mates, and its a powerhouse drug that just keeps on kicking!!!. i guess thats the problem...
