Electronic cigarettes as a harm reduction strategy for tobacco control: A step forward or a repeat of past mistakes?από την οποία:
The issue of harm reduction has long been controversial in the public health practice of tobacco control. Health advocates have been reluctant to endorse a harm reduction approach out of fear that tobacco companies cannot be trusted to produce and market products that will reduce the risks associated with tobacco use. Recently, companies independent of the tobacco industry introduced electronic cigarettes, devices that deliver vaporized nicotine without combusting tobacco. We review the existing evidence on the safety and efficacy of electronic cigarettes. We then revisit the tobacco harm reduction debate, with a focus on these novel products. We conclude that electronic cigarettes show tremendous promise in the fight against tobacco-related morbidity and mortality. By dramatically expanding the potential for harm reduction strategies to achieve substantial health gains, they may fundamentally alter the tobacco harm reduction debate.

Στο παραπάνω paper γίνεται λόγος για 2 κλινικές μελέτες:
Bullen, C., McRobbie, H., Thornley, S., Glover, M., Lin, R. and Laugesen, M. (2010)Effect of an electronic nicotine delivery device (e cigarette) on desire to smoke and withdrawal, user preferences and nicotine delivery: Randomised cross-over trial.
Eissenberg, T. (2010) Electronic nicotine delivery devices: Ineffective nicotine delivery and craving suppression after acute administration.
στις οποίες αναφέρεται το εξής:
Bullen et al demonstrated that electronic cigarettes deliver nicotine effectively, more rapidly than a nicotine inhaler. In this study, electronic cigarette use significantly reduced craving, a similar effect to what was observed with a nicotine inhaler.
Nicotine delivery and reduction in cigarette craving was much less than with a regular cigarette. Eissenberg found that 10 puffs on one brand of
electronic cigarettes delivered a small amount of nicotine, again far less than a tobacco cigarette, whereas another brand delivered little to none.
