Israeli scientists came to the conclusion that people who at the age of adolescence smoked are more likely to become addicted to alcohol in adulthood.
A study of scientists at the University of Tel Aviv showed that the culprit of this connection is not the nicotine itself, but a kind of memory of the organism about it.
They conducted an experiment on rats, which were exposed to nicotine when they were still small.
As a result, as soon as they grew up, they were placed in cells where there were dispensaries with alcohol.
It turned out that those rats who “smoked” at a young age, resorted more actively to alcohol and could get it on their own, stepping on a specially equipped lever.
In fact, “nicotine memory” contributes to long-term changes in the brain, which after many years can remind themselves, even when the teenager has already given up smoking.
Previously was reported about the fact that scientists from Edinburgh University conducted a study whose purpose was to find out how certain genes affect the expected life expectancy. To do this, the data of genetic studies of over 606 thousand people, as well as their way of life, were analyzed.
According to the authors of the work, smoking causes the most harm to the body, but this effect is reversible if you throw a bad habit. Negatively affects the expected life span and obesity, as excess body weight is associated with many diseases, including diabetes. “Extend” life can higher education: the year spent at the university, increased life expectancy by an average of 11 months.
