triple A is a classification of weed... it is the highest grade. it is like this...

AAA (this is the best they have in BC or Amsterdam; this is the stuff that the dealers smoke and doesn't get sold on the streets; if someone is saying they are selling it, its probs a lie but if you're lucky it is the real deal. i have tasted it a couple times when i lived in BC)
AA
A (this is most of the shit that kids slap a funky name like Orange Twist Haze and sell it over priced cause it is better than normal)
B (this is like your average highs, kind bud, dro, etc)
Etc etc
