Smoking makes the human brain smaller

Scientists have found out why it’s more difficult for a person to quit smoking if he is addicted to this addiction as a teenager.

Researchers who work in University of California (USA), reported that this bad habit over time makes the human brain thinner.

The fact that the earlier a person started smoking, the more serious are the consequences for his health, doctors have been talking for a very long time. Now scientists have talked about new evidence supporting this theory. If a person is addicted to cigarettes very early, then over time a smaller amount appears in his brain gray matterthan those who did not indulge in cigarettes in their teens. A decrease in gray matter is noted precisely in that fraction of the brain that is responsible for human decisions.

According to scientists, their discovery explains why it is difficult for smokers who are addicted to nicotine very early to give up this habit in adulthood. To refuse cigarettes, a strong-willed decision is necessary, which is very difficult for smokers with long experience to make.

Researchers have already concluded that thickness islet lobes changes precisely under the influence of smoking in adolescence. In addition, doctors suggest that the relatively small thickness of this brain area may increase the risk of an adolescent acquiring this bad habit.

Some people mistakenly believe that smoking a hookah, unlike smoking regular cigarettes, is not harmful. Recently, employees from the University of Florida have denied this thesis.

Smoke is especially harmful for teenagers who are attracted by the sweet and chilled taste of tobacco. Given this, they are sure that smoking a hookah is harmful to the body. Nevertheless, according to doctors, even one "session" of smoking a hookah can harm the health of a teenager. If you smoke hookah regularly, you can get sick with cardiovascular diseases and even some types of cancer.

As a rule, smoking hookah lasts at least 20 minutes, therefore, during this period, fans of this type of smoking exhale as much smoke as they get into the lungs when smoking dozens of cigarettes. Therefore, hookah is by no means a safe replacement for cigarettes.
