Canada is in the process of legalizing marrijuanna. They are considering pricing recreational pot at $10 per gram. My question is how many joints would that be if a gram was rolled into a joint the equivalent size of a cigarette?

At the dispensary here in California the joints they sell have exactly one gram in them.  They are a little bit bigger than a cigarette. Cost will depend on the kind of weed being sold and how much of that certain weed that they have. A gram of so so weed will run you about 5 dollars a gram. The high end stuff will run about 20-30 dollars a gram. 

3-6 joints, depending how they're rolled.
