The funniest thing about pot smokers... is that they think that only the people that they confide in are aware of their habit. News flash! News flash! Everyone knows you are a pot head. Test it out today... ask someone you don't think knows that you smoke pot. If they have even a smidgen of awareness and they are honest they will tell you that they know.
I have lived and worked with pot heads my entire life.
Well, this is probably true, but I daresay you've worked with far more that you didn't know about. Weed smokers don't necessarily increase when pot is legalized. They just come out of the toking closet. I'd say there is a slight increase, but in reality, many are just those that feel safe enough to be known as pot smokers.
