Are you allowed to sell cannibis to canadians that will be in Seattle for a few days. I do have a medical prescription card but can't bring my own over the boarder.

As long as your over 21 with a valid ID. Its treated like alcohol here.

Thank you Jackie for your quick response. Thought I would ask seeing as we were in the states but in a different state and I couldn't buy anything for my RA. We will be in Seattle in august staying near the Fish Market. Now I just need to figure out where to go

Should be a okay it's recreational anyone visiting the state can partake with valid I'd and 21+. I imagine you will have your passport
