In our previous article, we took stock of the currently known effects of electronic cigarettes of Eleafworld.FR on health. These were mixed, as is often the case in health when we have little epidemiological perspective on a practice. A recent Cochrane review returns to this thorny question of the benefits and risks of electronic cigarette use.
Undeniable short-term benefits
The review authors searched the scientific literature for studies using e-cigarettes to help patients quit smoking. They were looking for randomized trials and wanted to know how many people had quit smoking thanks to the electronic cigarette at six months and to take stock of possible side effects. Scientists found 50 studies (with a total of 12,430 patients) that met their inclusion criteria, which they had to review because too few randomized trials were available. The experiments compared the effectiveness of the electronic cigarette with nicotine with several other therapies such as:
nicotine replacement via patches or gums;
varenicline, a partial agonist of nicotinic receptors in the central nervous system;
the electronic cigarette without nicotine;
Using this data, the researchers conclude that people are more likely to quit smoking through nicotine e-cigarettes than using other nicotine replacement therapy or nicotine-free e-cigarettes. Likewise, the use of electronic cigarettes is superior to behavioral therapy alone.
In the long run, this remains to be proven
The investigators’ conclusion is as follows: “Electronic nicotine cigarettes probably help people quit smoking for at least six months. They probably work better than conventional nicotine replacement therapy and nicotine-free e-cigarettes. They may work better than no support or behavioral support alone, and they would not be associated with serious side effects. “
But the authors still wonder if the long-term effects are beneficial. Let us recall the fears that scientists had mentioned in our previous article: the risk of combining, in the future, the use of tobacco and electronic cigarettes. Also new models of e-cigarettes appear on the market offering a better supply of nicotine. The researchers warn that the benefits and risks of these new models will have to be assessed.
