Bella, you're right, the lowly little cigarette gets blamed for EVERYTHING! When in fact everything we eat, drink, and the air we breathe is full of carcinogens, and not from the small amount of smoke emitted from a cigarette. Our ground water is laden with chemicals and carcinogens from the fertilizers, pesticides and insecticides used in farming, and all the crap people put on their lawns to produce a "healthy" lawn. Our air is polluted with chemicals emitted from industry and the millions of cars on the road today. The ground water saturated with all the agricultural chemicals is what is used to grow our our vegetables and the corn used to feed our livestock.
I happen to live in an agricultural region and believe me all the cigarettes in the world can't hold a candle to all the chemicals used to produce a bumper crop of wheat, corn, sorghum, soybeans and livestock.
Most people are ignorant as to what they are eating, drinking and breathing on a daily basis. As a matter of fact tobacco in it's "natural" state produces very little toxicity when burned or inhaled. It is the CHEMICALS used in growing and processing the tobacco plant that make it a carcinogenic product, right up there with all the foods we eat and the air we breathe.
Enjoy your ciggies, try not to smoke in a confined area and make sure you have plenty of ventilation, no need to add insult to injury, and don't worry about what ignorant, naive people have to say. You will succumb no sooner to smoking, then eating, breathing and drinking the vast array of pollutants you're already consuming.
I know of several people in this area alone who have never smoked a day in their lives and yet died of various forms of cancer, including that of the lung, and others who have smoked a lifetime into their 80's and 90's and died of old age. So unless you have a genetic predisposition to lung cancer, I wouldn't worry too much.
Do smoke in moderation, get plenty of exercise, "eat healthy" ( I don't know if that's possible, unless you grow your own food organically in chemical free soil, and eat NO processed food) and don't let it bother you. Stress will kill you faster then anything else on this earth.
Face it, it's far easier to blame the lowly little cigarette for all of mankind's ills, then address the real issues, and clean up this earth; and far cheaper as well. I can promise you if every person on this earth quit smoking tomorrow, the incidence rate of cancer would only be 1 or 2% less. Then they would just have to find something else to blame everything on. It's always easier to blame the lesser of the evils, then to tackle the real problems.
Have a smoke for me and enjoy!
