Where there's smoke ...
Actress Jennifer Lawrence ("The Hunger Games" trilogy and the "X-Men" series) has been photographed smoking cigarettes and marijuana, and vaping. That's the trifecta of lung-damaging, life-shortening puffs. According to a trio of new studies, ditching cigs for vaping or marijuana isn't eliminating toxic chemicals or significantly reducing your increased risk of heart disease.
One study published in EClinicalMedicine found that both tobacco and marijuana smokers had potentially health-damaging levels of smoke-related toxic chemicals such as naphthalene, acrylamide and acrylonitrile metabolites in their blood and urine. These are known to cause everything from cataracts to increased risk of cardiovascular disease and damage to the lungs, skin and eyes.
Another study, published in Circulation, found that trying to reduce your cigarette use by also vaping didn't reduce your risk from inhaled toxins. Participants who used cigarettes and electronic cigarettes had the same levels of inflammatory and oxidative stress biomarkers as folks who smoked only tobacco cigarettes -- giving the same increased risk for cardiovascular disease and premature death.
The third study found that vaping and smoking tobacco clouds your thoughts -- and we know marijuana does too. According to researchers from the University of Rochester Medical Center, folks who smoke and vape, regardless of their age, are at greatest risk for problems concentrating, remembering or making decisions. Those who only vape or only smoke were found to struggle with mental fog almost as much as combo-smokers do.
So no matter what you puff, it's smart to stop. Check out www.smokefree.gov; look into cognitive-behavioral therapy and visit Freedom from Smoking Plus at www.lung.org/quit-smoking.
