Good Meth is way too strong, fucking scary, I used it a while - some time ago by now - by way of smoking (which should be least speedy most euphoric, and most fiendisch, which it was), but Hell, a tiny Crystal, one tiny toke, one huge cloud of vapor from that bowl blowing out, and instant headspace, major euphoria but not able to enjoy it because even the first toke already was way too speedy!
(I do am quite sensitive to speedy)
Anyway, the brain links this instant rush/euphoria to this hit, so it want's to keep hitting that pipe, so I would smoke way too much, man, thought I was a goner more than just a few times!
Never again for me!!! Meth is fucking evil!!!
EDIT: it's evil cause even when going too strong it is so fiendish and it gives huges cravings, so addictive, even if I didn't like two things about it at all: that it felt so synthetic in comparison to Coke which feels totally natural to me (my fav. drug ever) and that it's so speedy!
