I didn't know it was legal up here in Canada.. Map says it is, but I don't think so. I do know, if you try to cross the border into Canada, with marijuana (prescription or not) you will be ARRESTED. That prescription from California does not make it a prescription drug in Canada.
Here's a map but it doesn't say if it's legal in the entire country of each.
The only place I care about is California and then the rest of the U.S. They know how to tax it and regulate it. It's working fine in other states.
