Is vaping as harmful as traditional cigarettes? And other questions
While vaping is not harmless, it is far less dangerous than traditional, combustible cigarettes. Smoking causes 7 million deaths each year, including almost half a million deaths in the United State. Cigarettes are the leading cause of cancer. Nicotine causes dependence, but there are thousands of chemicals in tobacco smoke, including dozens of carcinogens and toxicants. It is these chemicals, not the nicotine, that cause tobacco-related diseases. Vaping products often contain nicotine, so vapers can become dependent. Because vaping does not involve combustion, far fewer harmful chemicals are inhaled. The scientific consensus is that vaping causes a fraction of the harm of smoking.
Emerging evidence indicates that switching completely to vaping can be an effective way to quit smoking. A recent clinical trial published in the New England Journal of Medicine reported that e-cigarettes were twice as effective as traditional nicotine replacement products such as nicotine gum or the patch.
Some flavors may attract nonsmoking youth to vaping, which we certainly do not want. But flavors also help smokers make the switch to vaping. Eliminating flavors may also push youths and adults back to smoking or to more dangerous black market products.
We should aim for balanced policies that promote public health across the population by discouraging vaping by youth, while also encouraging smokers to switch to vaping if other cessation methods have failed.
