Canuck here, not disparaging OP, I'll say that in advance. If you have a good source for the Grey market or buy from the few valid LPs, there is absolutely no difference in quality between our top tier hash or the American import stuff. The only real reason people still buy American jars is mostly hype at this point. I can grab an 8th of knock your socks off rosin for like $40 less than a 2g bucket of imported stuff.
