You Should Know: We all know by now that smoking isn’t healthy, but vaping is often perceived as the “better” alternative. New research suggests it may have hidden downsides, including a possible impact on blood sugar.

Going Deeper: A large study from the University of Georgia concluded that people who vaped were more likely to have prediabetes compared with those who didn’t vape at all. They also noticed that people with financial worries or chronic health problems seemed a bit more vulnerable. However, those who exercised regularly had a lower chance of developing these problems, so good daily habits might help mitigate the adverse effects of vaping.

Takeaway: It might seem strange that vaping and blood sugar could be linked, but different parts of the body are more interconnected than we often realize

Bottom Line: If you’ve been thinking about quitting vaping (or smoking for that matter), consider this another nudge. And if you don’t vape now, it’s probably best not to start.
