The American Journal of Preventive Medicine has published in its latest issue a study into the mortality risks of non-daily smoking in the US, comparing smokers who puffed a median of 15 days and 50 cigarettes per month with daily smokers, who smoked a median of 600 cigarettes per month. There are about nine million no-daily (or casual) smokers in the US.
Bad news: what else would you expect?
Compared with those who have never smoked, lifelong non-daily smokers have a 72% higher chance of dying from all the regular diseases associated with smoking.
