New Research Finds Rise of Frequent Cannabis Vaping Among U.S. High School Seniors

“Frequent vaping of cannabis now appears to be increasing at a faster rate than any vaping of cannabis,” says study author Joseph J. Palamar, MPH, PhD, an associate professor in the Department of Population Health at NYU Grossman School of Medicine and a researcher in the Center for Drug Use and HIV/HCV Research at NYU School of Global Public Health.

Study Findings

Palamar obtained data from a nationally representative survey of high school seniors in the U.S. from 2018 and 2019 called Monitoring the Future, with analysis focusing on a total of 12,561 students from 256 schools across 48 states. Analysis from 2018 to 2019 found:

• Past-month cannabis vaping increased from 7.5 percent to 14 percent, a relative increase of 85.9 percent.
• Frequent use increased from 2.1 percent to 4.9 percent, a relative increase of 131.4 percent.
• While increases in frequent vaping were detected among most subgroups of high school seniors, the most elevated increases were among female students (an increase of 183.5 percent), students 18 years or older (an increase of 154.9 percent), and those who go out four to seven times per week (an increase of 163 percent).
• Among students who used other drugs within the past year, the most notable increases were among those who used psychedelics other than LSD (an increase of 57.6 percent), those who used prescription opioids for nonmedical use (a 184.7 percent increase), those who used tranquilizers for nonmedical use (a 135.7 percent increase), and those who used cocaine (a 77.5 percent increase).
