Real-Time Antecedents of Young Adults’ Vaping and Co-Vaping of Nicotine and Cannabis: An Ecological Momentary Assessment Study

CTCRE Fellow Vuong Do, PhD is the lead author on a recently published article in the Journal of Medical Internet Research. The study used a smartphone app to check in with young adults several times a day—over 9,000 moments recorded in total—to see what triggered them to vape nicotine, cannabis, or both substances (same-occasion co-vaping). The study found that cravings and alcohol use strongly predicted vaping, whether it was nicotine, cannabis, or co-vaping. Seeing tobacco advertisements also made people more likely to either vape nicotine or co-vape, while seeing cannabis products was also associated with cannabis vaping and co-vaping.  

Researchers hope that pinpointing real-time events that precede nicotine vaping, cannabis vaping, or co-vaping, can help in the development of youth cessation treatments.
