Drug use at work

I share a office with someone and I know they smoke weed and also few others there also.I donot. To each his own. But today the office smelled So much like weed that everyone that came in there keen the smell. I don't care what she does in her private like but when you bring it to work and put me in a position that makes me look bad or may cost me my job.something as to be said .and we work in the medical field.

Speak up!! Before someone thinks it's YOU who's doing it. Something like: "Hey dude, you are bringing in that weed smell into the office. Either get some spray or run around the block after you smoke." (Is there a reason why you have remained silent all this time?)
