Scientists: the whites disappears nicotine dependence

Scientists from Poland found that representatives of the white race are beginning to lose dependence on nicotine. They conducted a study in six European countries. This effect is observed both in smokers and non -smokers. Currently, according to them, this phenomenon affects 43% of the population, and by 2030 it can potentially affect 100% of representatives of the white race. Scientists do not know the exact cause of this phenomenon. One of the theories suggests that this may be the result of coronavirus. Another theory proposed by the researchers indicates an evolutionary change that affects acetylcholine receptors that cease to distinguish the hormone of the pleasure of dopamine. This is not the first study of dependence on nicotine of this kind. There is an American study of the 80s, which shows that about 6% of white and 1% of asians can be insensitive to nicotine. In 2013, Italian researchers discovered that alcohol and sugar are also not influenced on the whites.
