People who used e-cigarettes were more likely to kick the habit than those who didn’t, a new study found.

Nicotine patches, gums and medications are known to aid smoking cessation, but there’s no consensus on whether vaping devices can help anti-smoking efforts. The U.S. research is the largest look yet at electronic cigarette users and it found e-cigarettes played a role in helping people quit.

“It’s absolutely clear that e-cigarettes help smokers replace cigarettes,” said Peter Hajek, director of the health and lifestyle research unit at Queen Mary University in London

Cigarette taxes are so so very lucrative though! The FDA ends up choosing cancer rather than harm reduction.
