@hawkeye10,
So you are a conspiracionist type fellow?
As a doctor i will say to you the same i tell to my patients. Smoking has a risk, as anything you drink or eat. The problem is the quantity. No one is telling you not to smoke. You can do so. Just be well aware of the risks it implies. The dangers of smoking are very very real. As well as Edgar had talked about knowing people who got sick because of smoking i can relate to many cases that i had seen on my years working as a primay care giver and in emerncy wards at a big city hospital.
The studies are made by non biased repescted investogators in world wide accredited medical journals that are respected by the medical community. Restrospective studies about the risks of smoking can be performed everywhere and very easily that is why there is no doubt that smoking is bad. As a medical students we have done as part of our stadistical epidemiolgy training.
We must trust our scientifical resurces and hear what the studies say because is the only way to provide appropiate health care. If you do not want to belive it, fine. Just please have a good health care insurrance and avoid smoking in enclosed places, and of course not in the presence of children.
Sadly i had know many cases of patients that never belived that they had diabetes, because "i never had any pain". They understand they mistake when they lose their first finger or a foot. The fact that there is no pain does not implies that smoking isn´t bad. I understand that it feels good, that inhaling that smoke makes you body relax, calms the aniety, helps you poop, and soothes your nerves. But as with alcohol and caffeine it has systemic effects that are well proved.
