The cigarette kills, not only those who smoke but also future descendants. It is not a mere question of secondhand smoke. Although exactly what happens is still to be understood, one thing is certain: children and grandchildren of smoking mothers have an increased risk of asthma.

La cigarette kills, not only those who smoke but also i future descendants. It is not a mere question of secondhand smoke. Although it is still to understand exactly what happens, one thing is certain: children and grandchildren of smoking moms have an increased risk of asthma.
This was discovered by a new study conducted at the Los Angeles Biomedical Research Institute ofHarbor UCLA Medical Center. According to the research, in the world they are 300 million people who suffer from asthma, and it is not excluded that most of them have to blame moms and grandmothers. And the situation is destined to worsen given that at this rate, by 2025 there will be 400 million cases of asthmatics in the world.
A major risk factor forasthma is that mom smoked in pregnancy. But what worries scientists is the fact that these negative effects are not short-term but are transmitted from generation to generation, through genes.
During the research, the scientists noted that mothers exposed to nicotine during pregnancy ensured an almost certain future for their grandchildren, asthma, even if the latter were not. never been directly exposed to nicotine.
Although further investigation is needed to clarify its role, the scientists believe smoking is likely to have the ability to influence people in some way. genes have been identified. of descendants, and especially those of theirs sperm and egg cell. "These effects can be passed down from parents to children over and over again, increasing the risk of asthma for subsequent generations," the researchers explain.
The study was published in American Physiological Society.
