I work full time as a supervisor in a restaurant. I am a very heavy smoker, I just make sure not to go in to work all blazed up. The majority of the people I work with smoke pot and do various other things, but no one really cares, as long as you show up on time and do you job correctly and courteously.

The restaurant industry in general has always been a safe haven for pot heads. No restaurant will drug test because they know they'd have to fire 1/2 of their staff!
