There was a request for comment to the tagging mailing list as the proposal for shop=marijuana, which from the discussion I was convinced to change it to shop=cannabis. It is still so infrequently used and other things have my priority, so have not continued the process. --User:russdeffner 17:57, 26 January 2015 (UTC)
These shops are popping up all over the place in Oregon. I've been adding a bunch of them in the Portland metro area. I haven't been making a distinction between medical and recreational marijuana shops; I've been using shop=cannabis for both kinds of shops. It's not obvious which shops sell only to medical marijuana card holders and which shops sell the the general (21 years or older) public. I know there were a number of shops that were open last year only for medical marijuana, but have since started selling recreation marijuana as well. I've read that in other states, the medical and recreational sales have to be separated and not directly part of the same shop, but in Oregon that is not the case.
