Summary
Introduction:
This text summarizes a research study on the relationship between cannabis use and electronic cigarette (ENDS) use, specifically focusing on the role of dual use on use frequency and related problems. The study tests whether dual use is related to more frequent use, use-related problems, and negative affect.
Key Points:
* The study found that among cannabis users, ENDS use was associated with more frequent cannabis use, cannabis-related problems, depression, and anxiety.
* among ENDS users, cannabis use was associated with more frequent ENDS use, more ENDS-related health problems, and anxiety, but not depression.
* The study also found that use of natural cannabis is prevalent among ENDS users, and that dual use of ENDS and cannabis is associated with greater frequency of use and related problems.
* Data was collected cross-sectionally, and future research should use longitudinal methods to determine directionality and causality.
* The study did not assess use of vaporized cannabis, and future work should test whether ENDS use is differentially related to natural vs vaporized cannabis.
* Data was collected via self-report, and future work could benefit from multimethod and/or multi-informant approaches.
* The sample was comprised of non-treatment seeking undergraduates, and future work should test the interplay of these substances among treatment-seeking substance users as well as other groups.
Main Message:
The study suggests that there are high rates of cannabis use among ENDS users and that over one-fourth of cannabis users also use ENDS. The greater frequency of cannabis use and related problems among ENDS using cannabis users is especially concerning. Future research is needed to further explore the role of ENDS in maintenance of cannabis use and use-related problems. It highlights the importance of understanding the relationship between cannabis use and electronic cigarette use, and the potential implications for public health and policy.
