Vaping suppresses the immune system

The annual conference of the American Association for the Advancement of Science in Washington was presented with evidence that vaping suppresses 6 times as many immune genes as smoking. After comparing genetic information swabbed from the noses of smokers, vapers, and non-users of both, researchers found that while smoking suppresses the activity of 53 genes involved in the immune system, vaping suppresses those and another 305.

Though research on the significance of that gene suppression is still ongoing, the initial results suggest that e-cig users may have compromised immune responses, making them potentially more vulnerable to infections and diseases.
