Man, this thread is going to vary so much. Getting an accurate answer will be difficult.

I know a lot of people here have the choice of "shag weed", "mids" and "highs", and also "hydro (dro)" as well. Not me though. We usually have highs around here all the time. Shag is unheard of, and mids, are rare.

Dealers usually go by grams, not by dollar amounts, but for $100, around here, I could get a half ounce. Dealers usually go by grams, and if they don't, they aren't a smart dealer:

1/8 (3.5g)=$35
1/4 (7g)=$60
1/2 (14g)=$100
full (28g)=$200

Again, some people in the US pay $400 for an ounce of highs, but some people pay $50 for an ounce of Shag weed. It varies. Quality over quantity I say. I'm in Alberta Canada by the way.
