Smoking is also prohibited in areas where there is a fire hazard, such as forests, and, of course, at gas stations
Go back further and youll see that not only was smoking permitted on airlines, but encouraged

Cellulose acetate filters (CAF) CAF are made from cellulose that is acetylated (converted to cellulose acetate), and is dissolved, and spun as continuous synthetic fibers arranged in a bundle called tow, which is plasticized, shaped, and cut to a suitable length to act as a filter.2 These filters are a rod of 12,000 fibers and, fragments of this material, it is known, they separate from it in manufacturing and are released on inhalation of the cigarette.6,7 The efficiency of CAF to remove particles from cigarette smoke is substantially influenced by the length and circumference of the filter, the number and size of the filaments, and the presence of additives in the fibers.2 The selective lack of absorption of this CAF is known except for phenol, but instead they allow cyanide and hydrogen sulphide to pass.2 Again, Pauly et al.6,7 found that the CAF fibers and glass particles were released and therefore ingested or inhaled when cigarettes were smoked
