According to new research from NYU’s Grossman School of Medicine published online May 4 in the Journal of Adolescent Health, frequent vaping of cannabis, defined as vaping at least 10 times, rose among high schoolers between 2018 and 2019. Seniors in the US more than doubled. The increase in frequent use was even greater in certain subgroups, e.g. For example, students aged 18 and over, students who reported using other drugs in the past year.

While some studies have looked at increases in cannabis vaping in general, little attention has been paid to vaping more frequently, which can increase the risk of developing a cannabis use disorder. Symptoms of cannabis use disorder according to DSM-V criteria include increased tolerance, repeated attempts to control or stop using it, spending a lot of time using it, social interpersonal problems due to its use, and giving up other activities in order to use it name a few.

“Frequent vaping of cannabis now appears to be increasing faster than vaping cannabis,” says study author Joseph J. Palamar, MPH, Ph.D., associate professor in the Department of Population Health at NYU Grossman School of Medicine and a researcher at the center for drug use and HIV / HCV research at NYU School of Global Public Health.

Study results

Palamar received data from a nationally representative survey of high school seniors in the United States from 2018 and 2019, entitled Monitoring the Future. The analysis focused on a total of 12,561 students from 256 schools in 48 states. Analysis from 2018 to 2019 showed:

  • Cannabis vaping last month rose 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 an increase in frequent vaping was seen among most subgroups of high school graduates, the increases were among female students (an increase of 183.5 percent), students aged 18 and over (an increase of 154.9 percent), and among students who were four Years old, are recorded the most up to seven times a week (an increase of 163 percent).
  • Among students who used other medications in the past year, the most notable increases were those who used psychedelics other than LSD (an increase of 57.6 percent), those who used prescription opioids for non-medical purposes (an increase of 184.7 Percent), those who consumed tranquilizers for non-medical use (an increase of 135.7 percent), and those who used cocaine (an increase of 77.5 percent).
