Many have noticed that people who like to drink can smoke a lot. But few know why these two bad habits are connected.
Scientists have stated that there is a link between smoking and drinking alcohol. This is explained not only by the fact that cigarettes invigorate, while alcohol causes a sedative effect.
The fact is that the reasons are genetic factors, writes med-heal.ru with reference to the works of scientists.
A study was conducted involving 158 families. Each family had two first-degree relatives who had smoked more than 100 cigarettes in their lifetime.
All participants completed a questionnaire. Various questions were asked: from the amount of alcohol consumed per day, month. A DNA analysis was also taken.
The scientists used linkage analysis, which looks for differences or variations in the DNA sequences of chromosomes inherited from parents.
There are gene variants that partially determine a person's behavioral characteristics in the future, for example, the presence of bad habits.
The research will continue. The main goal is to use this information to try to find individual treatments that will help get rid of negative hobbies.
