During the first half of the 20th century smoking was taboo for the young because the bad effects of smoking were known even then.
We oldsters didn’t call them “coffin nails” for nothing.
So----just as in booze,driving,voting etc---------smoking was considered an “Adult” pastime-----based on having reached a state of wisdom which allowed free decision,good or bad.
Of course,in those days, one could make up one’s own mind about one’s personnal habits.
We didn’t have,and didn’t need, government watchdogs and raving fanatics to tell us what to do and when to do it behind our own closed doors.
Every walk-of -life smoked----clergy,doctors,dentists,some nuns,mothers,fathers------pick a category.
If the second hand smoke theory had existed then-------the entire US population would have disappeared during the 20s and 30s
I started at age 9------and quit 71 years later after open heart surgery.
Just put them down and walked away------no patch needed.
And in that entire time I never had a coughing problem------go figure
