Living with someone who used tobacco products was associated with a higher incidence of cannabis in e-cigarette use (13%). Researchers also saw a higher use of cannabis in e-cigarettes among students of Hispanic ethnicity, compared with other ethnicities.
In 2015, around one-third of U.S. middle and high school students said they had used nonnicotine substances in e-cigarettes, but the use of cannabis in e-cigarettes could increase as several states consider legalizing cannabis sales for adults. “Given the high concurrent use of tobacco and other substances, it is important to monitor the substances youth use in e-cigarettes,” they wrote.
The researchers reported having no financial disclosures.
