Light smokers have been classified as smoking less than 1 pack/day, less than 15 cig/day, less than 10 cig/day, and smoking 1–39 cig/week (9, 14).
Among people who smoked between one and 10 cigarettes per day, the risk of dying from lung cancer was nearly 12 times higher than that of never smokers. The researchers looked at risk of death from respiratory disease, such as emphysema, as well as the risk of death from cardiovascular disease.
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.
On average, respondents in this group considered that smoking can cause cancer only if one smokes at least 19.4 cigarettes per day (for an average reported consumption of 5.5 cigarettes per day), and that cancer risk becomes high for a smoking duration of 16.9 years or more (reported average duration: 16.7).
In general, a light smoker is someone who smokes less than 10 cigarettes per day. Someone who smokes a pack a day or more is a heavy smoker. An average smoker falls in between. Sometimes a doctor will use the term pack year to describe how long and how much a person has smoked.

The mystery of why some people appear to have healthy lungs despite a lifetime of smoking has been explained by UK scientists. The analysis of more than 50,000 people showed favourable mutations in people's DNA enhanced lung function and masked the deadly impact of smoking.
Smoking one or two daily carries large risk
They found that compared with never smoking, smoking about one cigarette per day carries 40–50 percent of the risk for coronary heart disease and stroke that is associated with smoking 20 per day.
Heavy smokers have a reduced ability to discriminate between colours and contrasts. WASHINGTON D.C. [USA]: Smoking more than 20 cigarettes a day may damage your vision by affecting blood vessels and neurons in the retina, a study warns.
Among daily smokers, the average number of cigarettes smoked per day declined from about 17 cigarettes in 2005 to 14 cigarettes in 2016.
Every day smoker: An adult who has smoked at least 100 cigarettes in his or her lifetime, and who now smokes every day. Previously called a “regular smoker”. Former smoker: An adult who has smoked at least 100 cigarettes in his or her lifetime but who had quit smoking at the time of interview.
Having fewer than five cigarettes per day was associated with about two-thirds as much lung damage as puffing on 30 or more cigarettes per day, according to the study. Put another way, a light smoker could expect to lose about as much lung function in a year as a heavy smoker would in nine months. Study co-author Dr.
There is no safe level of smoking. Smoking even just one cigarette per day over a lifetime can cause smoking-related cancers (lung, bladder, and pancreas) and premature death (24, 25).
aag0299 Other organs were also affected, with the study showing that a pack a day led to an estimated average 97 mutations in each cell in the larynx, 39 mutations for the pharynx, 23 mutations for mouth, 18 mutations for bladder, and 6 mutations in every cell of the liver each year.
Light, occasional and social smoking also cause cancer
There is no safe level of smoking. Smoking 1-10 cigarettes per day increases the risk of getting smoking-related cancers and other diseases. Even smoking less than one cigarette per day is harmful.
Although the dangers of drinking and smoking are very different, according to annual death numbers, smoking is worse than drinking. In the United States, an estimated 88,000 people die from alcohol-related causes every year, but about 480,000 people die from tobacco.
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.
Smoking, anxiety and mood
Most smokers say they want to stop, but some continue because smoking seems to relieve stress and anxiety. It's a common belief that smoking helps you relax. But smoking actually increases anxiety and tension. Smokers are also more likely than non-smokers to develop depression over time.
Light smoker: a smoker who reports consuming between 1-10 cigarettes per day. Moderate smoker: a smoker who reports consuming between 11-19 cigarettes per day. Heavy smoker: a smoker who reports consuming 20 cigarettes or more per day.
Your lungs are a remarkable organ system that, in some instances, have the ability to repair themselves over time. After quitting smoking, your lungs begin to slowly heal and regenerate. The speed at which they heal all depends on how long you smoked and how much damage is present.
It's never too late to get benefits from quitting smoking. Quitting, even in later life, can significantly lower your risk of heart disease, stroke, and cancer over time and reduce your risk of death.
