Too little too late. Too many peolple have died due to passive smokoing. Killed by smokers disregard for others.
19,000 last year in Europe alone. My wike smokes (outside in her greenhouse/smoking room. She can do as she pleases, but pleases me, by not inflicting the filth into my lungs, or our childrens. My sister is a singer, and is always ill due to passive smoking from the audience.
If you must do it, do it away from those of us that prefer fresh air to the noxious outcast of smoking.
100 years from now, they will not believe we used to smoke.
