Mental Fog: Research Suggests Vaping Could Cloud Your Thoughts

Two new studies from the University of Rochester Medical Center (URMC) have uncovered an association between vaping and mental fog. Both adults and kids who vape were more likely to report difficulty concentrating, remembering, or making decisions than their non-vaping, non-smoking peers. It also appeared that kids were more likely to experience mental fog if they started vaping before the age of 14.

While other studies have found an association between vaping and mental impairment in animals, the URMC team is the first to draw this connection in people. Led by Dongmei Li, Ph.D., associate professor in the Clinical and Translational Science Institute at URMC, the team mined data from two major national surveys.

“Our studies add to growing evidence that vaping should not be considered a safe alternative to tobacco smoking,” said study author Li.

The studies, published in the journals Tobacco Induced Diseases and Plos One, analyzed over 18,000 middle and high school student responses to the National Youth Tobacco Survey and more than 886,000 responses to the Behavioral Risk Factor Surveillance System phone survey from U.S. adults. Both surveys ask similar questions about smoking and vaping habits as well as issues with mental function.

Both studies show that people who smoke and vape – regardless of age – were most likely to report struggling with mental function.  Behind that group, people who only vape or only smoke reported mental fog at similar rates, which were significantly higher than those reported by people who don’t smoke or vape.

The youth study also found that students who reported starting to vape early – between eight and 13 years of age – were more likely to report difficulty concentrating, remembering, or making decisions than those who started vaping at 14 or older.

“With the recent rise in teen vaping, this is very concerning and suggests that we need to intervene even earlier,” said Li. “Prevention programs that start in middle or high school might actually be too late.”

Adolescence is a critical period for brain development, especially for higher-order mental function, which means tweens and teens may be more susceptible to nicotine-induced brain changes. While e-cigarettes lack many of the dangerous compounds found in tobacco cigarettes, they deliver the same amount – or possibly more – nicotine.

While the URMC studies clearly show an association between vaping and mental function, it’s not clear which causes which. It is possible that nicotine exposure through vaping causes difficulty with mental function. But it is equally possible that people who report mental fog are simply more likely to smoke or vape – possibly to self-medicate.

Li and her team say that further studies that follow kids and adults over time are needed to parse the cause and effect of vaping and mental fog.

  1. Could? COULD? Haha. Your sucking in pure carbon monoxide. Are you stupid. The brain needs oxygen and nutrients. Anything else……….CLOUDS the MIND! Dumbass. Do not pay this idiot for this article.

    • Vaping doesn’t need to be harmless to be a healthy decision. I’ve been vaping for 10 years and I’ve had no issues with whatsoever. I have my respiratory health checked every other year during a physical. My lungs are far healthier after a decade than they were when I smoked for 4 years.

  2. Well, this explains a lot. Actually most smokers are kids anymore. And teen years are pretty confused anyway. Parents want you to grow up and still wear short pants. Nobody is sure who you are and neither are you. Have we all forgot the teen years?

  3. It’s probably a certain product or certain people. I can only speak for myself but I’ve been vaping for 9.5 years and I’ve had no problems affecting my concentration or mental clarity whatsoever. Vaping is still in it’s infancy though so there’s not enough data regarding the long term health effects

  4. It’s probably a certain product or certain people. I can only speak for myself but I’ve been vaping for 9.5 years and I’ve had no problems affecting my concentration or mental clarity whatsoever. I have a physical every other year during which I have my respiratory health checked and I’m perfectly healthy. I could barely walk up a flight of stairs without getting winded when I was a smoker. Vaping doesn’t need to be harmless to be a form of harm reduction. I’ve only experienced positive effects of switching to vaping.
