Research Update on Vaping

Tin, aluminum, lead, and zinc: those are the metals that were found in the aerosol generated by various e-cigarette devices in a recently published study. Sounds like exactly what you want to inhale deep into your lungs, right?

Researchers in Maryland recruited volunteer vapers to test the liquid in the tank, the aerosol, and the remaining fluid in their e-cigarette tanks; 56 subjects provided their e-cigarette for analysis. Testing these metals is no easy task. All samples were collected in sterile conditions, and all tests were compared to samples known to be pure and also with calibrating liquids. The objective was to see what contributions the heating coil might have made to the metals in the aerosol.

Levels of tin, aluminum, lead, and zinc increased after exposure to the coil and the heat it generates, and that’s being distributed into the lungs. Did the metals all come from the coil? No, the e-liquid already had the metals, but the amounts increased after conversion to aerosol.

This adds to the growing body of research that suggests vaping is not benign and is potentially harmful. We won’t know how harmful for years, possibly decades, when those who began vaping years ago are tested and found to have higher rates of lung disorders. If you continue to vape, you may look forward to being one of those subjects. It’s your body. It’s your choice.
