Great

You probably do (employ and associate with) if you employ and associate with many people. I would feel as comfortable employing someone who smokes on occasion as a social drinker. I think that the irrational judgements are made by misinformed people who have never smoked and have either heard or read a ton of nonsense. I would feel safer spending time with someone smoking that someone drinking heavily. The drinker is way more likely to become aggressive and abusive than the smoker. The worst that the smoker is likely to do is go searching for oreos, cupcakes and dingdongs and spend the evening contemplating the universe. There are worse things.
