There is no safe amount of smoking. Every cigarette causes some harm to the body. Once smoke touches the lips, it begins to attack living tissues, and it continues its attack wherever it goes. Cigarette smokers have less ability to carry oxygen to the rest of the body. This is why smokers have less endurance when running or participating in sports.
Smokers also get wrinkles at an earlier age.
The smoke changes the elasticity of the skin and fine lines appear around the eyes. Your clothes and hair will smell. And kissing a smoker is like kissing an ashtray. The infections are a result of damage to cilia in the lungs. Cilia are tiny parts of the lung that act like little brooms, sweeping out bacteria, viruses, and dirt.
