What this could lead to
If it works, this could point toward a way to help smokers with asthma cut down on cigarettes and possibly improve their lung function.
What could go wrong
This was a very small study (17 people) with no control group, so results may not apply widely. The long-term safety of e-cigarettes is still unknown.
