What does 5 years of smoking do to your lungs?
Long-term smoking can lead to emphysema, a type of chronic obstructive pulmonary disease (COPD). This condition destroys a portion of the lungs known as the alveoli, which is where the exchange of oxygen and carbon dioxide takes place, Edelman said. People with COPD have shortness of breath and difficulty breathing.
How much smoking is bad for you?
Just one to four cigarettes a day almost triples your risk of dying from lung cancer. And social smoking is particularly bad for your heart, as bad as regular smoking, it seems.

Background: Heavy smokers (those who smoke greater than or equal to 25 or more cigarettes a day) are a subgroup who place themselves and others at risk for harmful health consequences and also are those least likely to achieve cessation.
How many cigarettes a day is safe?
Conclusions: In both sexes, smoking 1–4 cigarettes per day was associated with a significantly higher risk of dying from ischaemic heart disease and from all causes, and from lung cancer in women.
Why does it feel good to smoke?
Nicotine and other chemicals in tobacco smoke are easily absorbed into the blood through the lungs. From there, nicotine quickly spreads throughout the body. When taken in small amounts, nicotine causes pleasant feelings and distracts the user from unpleasant feelings.

Does smoking make you skinny?
Smoking’s effect on body weight could lead to weight loss by increasing the metabolic rate, decreasing metabolic efficiency, or decreasing caloric absorption (reduction in appetite), all of which are associated with tobacco use. The metabolic effect of smoking could explain the lower body weight found in smokers.
Can lungs heal after 40 years of smoking?
The mutations that lead to lung cancer had been considered to be permanent, and to persist even after quitting. But the surprise findings, published in Nature, show the few cells that escape damage can repair the lungs.
