I went on a little 2 day trip and stayed at a nice hotel. I've stayed there before several times. This was the first time I had to sign that I wouldn't use medical marijuana in the room, it has said no illegal drugs in the past. It had never included medical marijuana though. This happens to be a casino and people are smoking like chimneys everywhere, except in designated rooms. I had a non smoking room, but in the past when I would combust I would get a smoking room and use incense and a lit cigarette to help mask the smell. This time I used my vaporizer and had a oil diffuser going, I didn't have any problems. I didn't like having to sign that I wouldn't use medical marijuana but I did. I understand the oder factor with smoking cannabis. Most folks aren't familiar with vaporizers unfortunately. I live in a legal state for cannabis and hotels can choose to allow that or not. Hopefully some hotels in Seattle will allow at least vaping in some of their hotels or they won't get the cannabis tourists. Where are they going to try out their product that they bought? You can't use cannabis in public is the law, but folks do anyway. I used my vaporizers while walking on the beach, nobody noticed anything, for you folks wanting to come to WA.
