A new study reveals that there are similarities between nicotine and cannabis vaping use in teens and young adults, and that they are mostly used at the same rate. Many reported using both substances, and those who reported vaping nicotine at a younger age also reported to have used cannabis.
The results took into consideration age, parental education level, gender, race, and ethnicity as it assessed the rate of vaping use for both cannabis and nicotine. All of these questions were asked in the self-reported surveys the youth participants completed.
This study, which was published by JAMA Network Open, looked at instances of use from teens and young adults in the United States. It took data from students at high schools across Los Angeles at six-month interviews as they went through their last two years of high schools, then a year or two after finishing high school.
“Growth mixture modeling (GMM) was used to identify latent trajectories of vape use. Parallel GMM was used to assess co-occurrence of nicotine and cannabis vaping trajectories,” the survey says regarding the method used to identify comparisons that were not readily obvious to those looking for patterns.
“For each nicotine-use vaping trajectory, the probability
