well I dont think you should have anything to worry about if you're aware of the fact that you know you don't wanna be addicted to that shit.
i did it for a little while but I don't really like it, and i'll only do it if it's free (everyone knows powder is not cheap)
but see, my friend, she does like it a lot, so she decided to never do it again. i think if you kno yrself and yr aware of what yr doin then you can decide.
