Lung cancer is the most common form of cancer caused by smoking. More than 80% of cases of lung cancer are due to smoking.Cigarette smoke contains many chemicals that interfere with the body's method of filtering air and cleaning out the lungs. The smoke irritates the lungs and leads to overproduction of mucus.ong term exposure of the lungs to the irritants in tobacco smoke destroys the normal lung structure. The elastic walls of the small airways within the lungs are broken down. This reduces the amount of lung tissue available for the transfer of oxygen from the air to the blood.
Tasers differ significantly from standard stun guns. The shock of a Taser is delivered by wires. These wires are fixed with electrodes on their ends. The wires are shot out the end of the Taser gun with a range of up to 20 feet.
Although this site is dedicated to firearms, I thought I would post an effectiveness comparison of the various self defense tools. These are guns, Tasers, pepper spray, and edges/blunt objects. Guns. Pros: The most effective way to stop an attacker yet invented by humans. Works up close, and at a distance. Can be less expensive than a Taser. Cons: More expensive than pepper spray. I consider firearms to be the most effective means of self defense.
