Vaping Weed May Be Worse for Lungs Than Smoking, Study Shows

Vaping cannabis may put teens at a greater risk for developing symptoms of lung injury than those who smoke cigarettes, or marijuana, or who vape nicotine, according to a new study.

Adolescents were about twice as likely to report wheezing or whistling in the chest than those who used e-cigarettes or smoked, findings from the University of Michigan showed. The researchers also evaluated whether participants reported a dry cough at night that wasn’t linked to a temporary infection or sounded wheezy during exercise.
