The list of problems related to smoking goes. Thus, the cigarette would not simply of rider our skin, cause bronchitis and cancer, misleading us dependency but it would also contribute to the morale to zero. Of the least, if according to a study undertaken in adolescents by Drs. Elizabeth Goodman and John Capitman.
For many years, doctors know that many smokers are depressed. For this reason, the withdrawal must be accompanied with infinite precautions and it is not uncommon that is advised to some “intoxicated” to delay this difficult time to make it happen at a better time. Some adults wishing to put an end to smoking, the use of antidepressants may also be required to increase the chances of success.
Against conventional wisdom
Nevertheless, the findings of the study, that come to us doctors Goodman and Capitman of the University of Cincinnati (Ohio) and Brandeis University in Waltham (Massachusetts), go against the grain of conventional wisdom. For these researchers, is smoking not because you are depressed but it would become depressed by smoking. A rather iconoclastic idea so far.
Surveys among American adolescents
To demonstrate, scientists have used data collected in 1995 and in the United States in a national study on the health of adolescents in 1996. They watched the relationship between depression and smoking for a year. On the one hand, 8 704 non-depressed adolescents, investigated if those who were, were likely to become smokers. On the other hand, young people 6 947 considered as non-smokers, it has attempted to establish if those handing over to the cigarette more could become depressive.
Four times more depressed smokers
The results of these studies are clear. Smoking has proven to be the parameter increasing more than the likelihood of developing depression. The teens initially not depressed, who began to smoke, were thus victims of this condition almost four times more often than other young people after one year of follow-up. In addition, if 4.8% of non-smokers have become depressed during the duration of the inquiry, this proportion reached the record figure of 12% among young people who already smoked a pack of cigarettes a day at baseline.
The Blues is not conducive to smoking
The analysis of the results observed in 6 947 non-smoking adolescents revealed, however, that the “depressed” does not lead to become “addicted”. Indeed, initially depressed adolescents were not more likely than other youth to become regular smokers.
How is smoking?
It remains to understand how smoking causes harmful effects on the psyche. We already know that some antidepressants increase the effectiveness of smoking cessation. Thus, the hypothesized that nicotine or other toxic substances in tobacco could promote the onset of depressive symptoms. This possibility does not, appear on its face, so farfetched. Like most drugs, nicotine attaches to synaptic receptors in the brain and causes changes in metabolism in the central nervous system. Case to follow accordingly.
