Genetic characteristics make teenagers smokers

Scientists have established that genes, and not willpower, influence whether a person becomes a smoker. Doctors have discovered genetic variants that increase the risk of severe tobacco dependence in adolescence.

Adolescents who have found such a variation of genes, most often show an interest in smoking and easily reach up to 20 cigarettes per day. By adulthood, they are so accustomed to smoking that they can no longer refuse it.

This was shown by studies of about 1,000 people from New Zealand. According to Dr. Daniel Bielski of Duke University, genetic predisposition is responsible for the addiction and how many people a day will smoke a cigarette.

Doctors have discovered that the risk group has changes in the DNA next to the genes that respond to nicotine.Therefore, if a teenager is endowed with a problematic variation of genes, then the probability that by the age of 15 he will smoke every day is higher by 24% than among those who do not have this variation of genes. The probability that by the age of 18 a person will smoke up to a pack of cigarettes a day is 43% higher.
