Even one cigarette a week is bad for your health. Each cigarette you smoke exposes you to nicotine and other harmful chemicals and increases your risk for heart disease and cancer. The negative effects of smoking add up over the course of your life.

Long-time smokers will take longer for their lungs to improve. Some damage from smoking is permanent. Unfortunately, your alveoli cannot restore themselves, but stopping smoking will halt the progression of COPD and improve your ability to breathe.
Smoking one cigarette per day carries around 40-50% of the excess risk for developing coronary heart disease and stroke of smoking 20 cigarettes per day, and smoking five cigarettes per day has around 55-65% of the excess risk (particularly when we focused on studies that reported relative risks adjusted for multiple ...
The study shows that smokers die relatively young. An estimated 23 percent of consistent heavy smokers never reach the age of 65. This is 11 percent among light smokers and 7 percent among non-smokers. Life expectancy decreases by 13 years on average for heavy smokers compared to people who have never smoked.
Light smoking is defined as smoking five or fewer cigarettes per day. It can also mean skipping cigarettes some days and picking one up occasionally. “Light smokers may not consider their occasional habit as harmful. They may not even consider themselves smokers.
"Our data suggest that these individuals may have survived for so long in spite of their heavy smoking because they managed to suppress further mutation accumulation." They may simply have "very proficient systems for repairing DNA damage or detoxifying cigarette smoke," he said.

1: Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.
