Sécurité d’emploi de la nicotine au long cours : le débat n’est pas clos

[Exposure of vapers to formaldehyde and acrolein: A systematic review]

Although recognized as less dangerous than conventional cigarettes, the toxicity of the electronic cigarette vapor's toxicity remains to be fully assessed. This review explores vapers' exposition to formaldehyde and acrolein.

METHOD

Systematic PubMed search for reports regarding formaldehyde or acrolein or their metabolites in electronic cigarette vapor, in vapers, or in ambient air.

RESULTS

Fifty-two publications were selected. Found in almost all studies on vaper, formaldehyde is 8 times out of 11 - and acrolein constantly - in lower amounts than those found in conventional cigarettes. Acrolein's metabolite is found in all studies in vapers. The concentrations of formaldehyde and/or acrolein generated during vapor production may be affected by the characteristics of the E-liquid, voltage, vaping topography, and by the flavor additives.

CONCLUSION

In the current state of knowledge, we must continue to support and help smokers to quit smoking, and for those who are engaged in a harm reduction approach, to minimize the duration of their electronic cigarette use.

[Smoking cessation: A challenge for cardiologists and pulmonologists]

In addition to public health measures that need to be strongly supported politically, smoking is also a major medical issue. Tobacco dependence is a chronic disease, and, given its extremely addictive nature, treatment for tobacco dependence must be addressed actively by all health professionals. Because smoking is a major contributor to many of the pathologies their specialties address, cardiologists and pulmonologists must be at the forefront of this care. In this review we analyse the current state of smoking cessation treatment and its inadequacies, the limiting impact that doctors' own smoking has, as well as the misconceptions held by smokers and sometimes by doctors as well, which act as brakes on smoking cessation. Smoking cessation must become a treatment delivered in real clinical practice and any doctor must know how to manage it fluently. Do not be satisfied with simply advising smokers to quit. Learn how to approach the subject with smokers effectively, know how the various pharmacotherapies are used and know how to organize smoking cessation follow-up, an essential guarantee of success. If optimal management of this major pathological factor is a role for all doctors, it is of course especially so for our two specialties. It's up to us, cardiologists and pulmonologists, to take up this challenge.
