Dude! What Do You Do When Your Neighbor's Marijuana Smoke Seeps in?

Oct. 22, 2014 — A lot has been written about secondhand cigarette smoke, and some New York co-ops and condos, including Manhattan's massive Zeckendorf Towers, have initiated building-wide smoking bans. But what of secondhand pot smoke migrating from one apartment to another? Though pot has been "decriminalized to some degree," writes Ronda Kaysen in The New York Times' "Ask Real Estate" section, it's still illegal in smokable form — medical marijuana not being smokable — so that's a complicating factor when a neighbor is lighting up. Assuming that you're neighborly and don't want to harsh his mellow, here are some options to keep yourself and your family from possible contact high and lung irritation. As for what a co-op or condo board ought to do, well, that's a joint of a different color.
