Oct. 25 (UPI) -- More than one in seven adolescents and teens in the United States and Canada has vaped marijuana in their lifetimes, an analysis published Monday by JAMA Pediatrics.
Pooled results for nearly 200,000 people ages 11 to 18 from 17 studies indicates that 14% used e-cigarettes to smoke the drug, also known as cannabis, at some point as of 2019-20, the data showed.
This is up from 6% between 2013 and 2016, the researchers said.
In 2019-2020, an estimated 13% of people in this age group vaped marijuana during the previous 12 months, up from 7% in 2017-18, according to the researchers.
And just over 8% had used the devices to consume the drug over the previous 30 days in 2019-20 compared to fewer than 2% between 2013-2016.
"Adolescent cannabis vaping is becoming more common in the United States and Canada," study co-author Carmen Lim told UPI in an email.
"Not only is it linked to poorer cognitive development in adolescents, [but] it could increase risk of dependence, other substance use and many other health, social and behavioral problems later in life," said Lim, a doctoral candidate at the University of Queensland in Brisbane, Australia.
Previous studies indicated that as many as one in five adolescents and teens in the United States regularly use e-cigarettes, or vaping devices, to smoke marijuana, and that the habit is more common among people in this age group who are Hispanic than those who are White or Black.
This is despite links between the use of illegal marijuana vaping devices and serious lung injury.
For this analysis, Lim and her colleagues analyzed data from 17 studies that collectively tracked the marijuana vaping habits of 198,845 adolescents and teens in the United States and Canada.
In addition to identifying the increased use of these devices for marijuana within the age group, the findings also suggest that cannabis oil, as opposed to dried leaves, now may be the preferred option, particularly in the United States, the researchers said.
"Cannabis vaping is a new phenomenon, [but] we can draw examples from global tobacco and alcohol policy, both of which have achieved successes in reducing prevalence and minimizing harms," Lim said.
"For example, cannabis marketing and advertising of THC products through targeted ads on the internet should be strictly regulated. Policy makers can also consider imposing a potency- and weight-based tax defined by THC levels," she said.
