E-cigarettes could be used to help combat obesity in smokers trying to quit

Researchers in Britain and New Zealand have found a potential new use for electronic cigarettes in smokers who want to give up - controlling appetite and limiting the weight gain that often comes with quitting. In a review published in the journal Nicotine & Tobacco Research, the scientists found that it's the nicotine in cigarettes that makes smokers less likely to overeat, and suggested e-cigarettes, which contain nicotine but no tobacco, may help prevent them from eating too much when they quit. 

E-cigarettes, which heat nicotine-laced flavored liquids into a vapor, have rapidly grown into a global "vaping" market that was estimated at around $7 billion in 2015.
