A better answer would be to set up the "smoking" apartments with exhaust ventilation, and to improve the sealing around plumbing, etc. in all apartments, so as to curtail seepage. The apartment I last lived in had a lot of seepage from my smoking neighbors. It was enough to be annoying. Duct tape around the plumbing at the walls helped.

Duct tape around the plumbing at the walls helped.

Or one could use duct tape on captured board members.
