***CORRECTION***

Just spoke to my friend... Indeed you can smoke pure weed/hash in the coffee shops like normal, only the tobacco has to go into the separate room.

Still, I liked to put in juuuust a little tobacco in my joints... it made the taste a little better and it burned nicely also. I guess I have a hard time picturing my favorite coffee shop with a separate booth that people have to go into to smoke cigs and mixed joints, seems like it would take away from the atmosphere of the place.

Just wanted to clear that up... Sorry for the confusion
