I'm surprised no one's mentioned it yet, but if you need to smoke, there's a good way to partially cover up the smell.

Go smoke near a window, stuff a paper towel tube with a few of those fragrant dryer sheets, and after you take your hit, blow it through the cardboard tube out the window. A bit of smoke may come back in, but it doesn't smell like pot in my experience, it's just neutral-smelling smoke for the most part.
