omg....why cant people just go out and get real recreational drugs to snort, leave the medical stuff for medical reasons damnit! pay the dealer-tax like the rest of us! (altho u can exclude me from 'us' as i dont snort stuff, or jab it, and i dont even smoke it anymore...ahem...heh)
couldnt be arse to read more than the first few posts and the last few posts...all i can say on what i did read is if she is into doing this often (say every weekend, or at every party she goes too etc) then get the hell outta dodge, or be a man and stop her doing it....
if she has just done it the once, tell her she is stupid and you'd rather she got drunk....
oh and as for the underage drinking thing, move to england, then she be legal 🙂
(btw, cant remember, is it american law that you cannot DRINK alcohol before 21, or just that you cant BUY alcohol?....in England there is no law against drinking alchohol at a young age, but obviously the person permitting too young a person to drink more than a minor amount of alcohol will be prosecuted if found out...or rather if the police can be arse to prosecute..lol)
