ABSTRACT

INTRODUCTION: Current measures of vaping behaviors do not distinguish what substances participants are vaping and to what extent they are dual-vaping nicotine and cannabis. This study describes the use of new survey questions that more specifically ask whether participants who vape are vaping nicotine, cannabis, CBD, or another substance.

METHODS: Adults, who reported any past-30-day tobacco use, from five New England states participated in an online survey from April 2021 to July 2022. Participants who vaped were asked, “Have you used any of the following vape substances in the past 30 days?” with the possible responses of nicotine, cannabis, CBD, other, and “don’t know.” Dual-use of both nicotine and cannabis was defined as the vaping of both nicotine and cannabis and/or CBD in the past-30-days, operationalized as a dichotomous outcome. Data were collected in monthly, repeated cross-sectional waves. Multinomial logistic regression was used to examine correlates of dual-vaping.

RESULTS: The analytic sample included 1547 adults who reported past-30-day tobacco use (mean age 42.9 years, 62.8% female, 85.4% White, 48.5% income of less than $50,000). Over one-quarter (26.1%) reported dual-vaping in the past-30-days. Identifying as male (p=0.002) and self-rated anxiety (p=0.043) were associated with a higher odds of dual-vaping.

CONCLUSIONS: Our findings show that a sizable proportion of a sample of New England adults who have used tobacco in the past-30-days are dual-vaping nicotine and cannabis. Adequate survey measures for assessing the vaping of multiple substances can help in better screening and characterization of health behaviors around dual-use.

IMPLICATIONS: This study addresses a key gap in adequate survey measures for assessing vaping of multiple substances. We found that among adults with past 30-day tobacco use, dual-vaping was prevalent and associated with different correlates, such as self-reported anxiety and education level, compared to sole-vaping of nicotine or cannabis. Our findings may help in characterizing and targeting future population-level surveillance and intervention efforts for multiple substance use behaviors.
