fields of both groups showed that
smokers, there is a specific gene - CYP2A6, which can be
expressed in three different variations. Fans of tobaccomoreoften than people with this
habit committed suicide occurs so-called del-smoking version of the gene.



Scientists argue that the "tobacco" the gene acts in a way that the body
hampered the process of splitting of nicotine, so the level in the blood remains
consistently high. Refuse a cigarette in such circumstances means sharply
reset the level of nicotine that the body is equivalent to severe stress.
That's because the nicotine in their bodies practically not split, smokers
with del-version of the gene to tobacco are not inclined to smoke a lot of cigarettes.
After all, for sustaining a high level of nicotine they only a few
puffs.



An important discovery was the fact that the owners of del-smoking version of the gene
were less susceptible to disease - pulmonary emphysema. Explain
This phenomenon, scientists can not yet. They merely suggest that the "tobacco" gene
prevents the formation of substances in the body, contributing to the development of this disease.




Experts say that their unique discovery can be used to "rescue"
of the potential for tobacco dependence "genetic" fans smoke. In their
view, DNA testing for the presence of gene smoking warn habit.
