Hey there, I live in Vancouver too! First off, the cost of housing is pretty expensive but it depends on where exactly you are going to move. I live close to downtown Vancity and I pay $1000/month for a one bedroom, 750 square foot apartment in a really good area. The actual cost of living is pretty cheap IMO. As for weed prices, I can tell you that I usually pay between $40-$50 for a quarter ounce. You can find stuff for cheaper though, and of course you can always find super-good stuff that is much more expensive.
