text: amazing how simple minded fools belittle my mother's accomplishments, especially after she spent 40+ years fighting for better safety laws protecting blue collar workers. You're not going to find anything on the subject today as for the last 30 years there has been a war on tobacco. Everything written on the subject  covers a heavy smoker., which as I stated is quite harmful and especially for asthma. Before inhalers and drugs, doctors-nurses prescribed 1 cigarette a day to help asthma patients as you will find all over Google, people who attest a smoke helped them breath easier. That's 1 a day, not 20. this is why back in the 60's my mother told patients to do just that, which was common, not because of big tobacco as your delusions allude to when demonizing the industries she worked for with grade school tripe.
