Don't worry about it. Some of the oldest people in the world, smoke, and drink like a fish!
It's eating all the Plastic in our food, and Chlorine, and Fluoride, in our water nowadays, you should be more concerned about!
Yes, there are some people live to a very old age who smoke, drink and defy all the traditional advice about maintaining health. But the majority of people who smoke have a shorter life and poorer quality of life than non smokers.
There are now so many scientific studies that prove the dangers of smoking. BioMed Central is an internatonal research agency with a substantial reputation. One of their studies concludes:
"In this large-scale, population-based Australian study, death rates in current smokers were around three-fold those of people who had never smoked, in both men and women. On average, smokers died around 10 years earlier than non-smokers, over the ages examined.
The risks of cancer, cardiovascular disease, respiratory disease, and a range of other health problems are increased in tobacco smokers and, as a consequence, smokers are more likely than non-smokers to die prematurely [
1]. Smoking is a leading cause of morbidity and mortality in virtually every country in the world and is second only to high blood pressure as a risk factor for global disease burden [
2]. It is arguably the leading readily preventable factor."
While we are in danger from plastics at an individual level we may join protest groups and strive to lesson the danger but it is clearly going to take many years to bring about significant change. On the other hand, regarding smoking, we can make an immediate turn around with health and longevity expectations. Simply... stop smoking.
