We found a solution for second hand smoke without banning smoking in our building.

We've been fighting a second hand smoke problem in our coop for years. 2 heavy smokers on one floor have caused the hallway to smell all the time and smoke has seeped into other apartments. We brought in consultants who suggested sealing openings between apartments and improving our air flow from the hallway through kitchen and bath vents in the apartments. None of this worked.
We finally found a consulting engineer who had experience with smoke issues in apartment buildings. One of the findings of the engineer was that every time our elevators would travel up or down our the vacuum in the elevator shaft would cause air to be drawn into the hallways from the apartments bringing the smoke into the hallway. Regular door seals were not enough. An acoustical door seal kit, which incorporates a sealing gasket all around the door and a drop down seal at the base needed to be installed to ensure that nothing exits the apartment through the door. This also required replacing the door thresholds. In addition, all the openings on the common walls between apartments needed to be sealed with an acoustical sealer. The regular foam sealants were not good enough. The sealing between apartments was necessary since, if the door was sealed, the smoke would be sucked through a common wall and end up in the neighboring apartment and hallway. We found a locksmith that had experience with the door seal kits and charged about $600 each. The smokers were required to pay for the work.
The hallway is now smoke odor free and you can now smell the normal cooking odors.
