Smoking can have an immediate impact on health, causing problems such as bad breath, yellow teeth, and headaches. If a person continues to smoke, the long term consequences of this behavior can be far more serious. The person might develop lung cancer, heart disease or emphysema as a result of smoking habits. The mental/emotional side will be affected because when you feel sick and physically unattractive you feel bad about yourself. The social health will be affected because that behavior can alienate you from others. Many places condemn smoking, people who smoke are not allowed also many people do not like the smell of tobacco.
