E-cigarettes and electronic nicotine delivery systems should be better..E-cigarettes and electronic nicotine delivery systems (ENDS) have not been scientifically validated and may be more dangerous than they are often considered, according to the International Union Against Tuberculosis and Lung Disease. The Union issued a new position statement in November on e-cigarettes and ENDS, calling for stricter regulation of these products, which are rapidly growing in popularity.
Among the only randomized trials on their efficacy was conducted in New Zealand. The study randomized 657 smokers who wanted to quit to either nicotine e-cigarettes, nicotine patches, or placebo e-cigarettes. After 6 months, verified abstinence from smoking was found in 7.3% of nicotine e-cigarette patients, 5.8% of patch patients, and 4.1% of placebo patients; they concluded that there was thus insufficient statistical power to determine any differences, and that more research is “urgently needed” to establish benefits of the devices.
The Union also points out that regulation of e-cigarettes and ENDS varies widely around the world, and they advocate regulating them as medicines. Some countries, including Brazil, Norway, and Singapore, have simply banned the devices.
“E-cigarette and ENDS manufacturers and vendors have been vocal about the supposed benefits of their products and quick to shout down calls for regulation or questions about their contents,” Castro said. “Based on our review of the available evidence, we strongly support the regulation of the manufacture, marketing, and sale of electronic cigarettes or electronic nicotine delivery systems; and our preferred option is to regulate these products as medicines.”
