When you quit smoking, the resin settling from cigarettes in alivises and bronchuses is coughed out. If because of this resin it is very difficult to quit and eat, it is necessary to come up with a gas that, reacting with this resin, decomposes it on gases that can then be exhaled. In my opinion, it is also possible to come up with a liquid, the vapor of which would be inhaled and condense on the surface of alivia and bronchus.
