I wish I could give you some good information, but from what I see at the dispensary I go to, the people behind the counter make minimum wage. They even have a tip jar!

I told one guy, listen, you guys should demand higher wages because the political winds could change, and putting down on your resume that you worked at a pot dispensary could kill your chances of getting hired, so there should be a hazard premium here. Sadly, the work requires no skill, so they really can't demand raises. :~(
