The New York Times Social Q's

A new friend of mine submitted a question for the New York Times' Social Q's column. It was featured in yesterday's paper:

Potted Neighbor

In our apartment building, a guy smokes pot frequently. In Seattle, where I live, pot has been designated a low priority for our police department.

I have nothing against it, but the constant smell is making me ill. Is there a polite way to ask him to stop?

Read the response here. Kudos to Blaire. And how apropos of today's celebrated activity.
