Daily patterns of substance use among young adults who vape nicotine and cannabis: Latent class analysis of smartphone-based daily diary data

CTCRE fellow Deanna Halliday, PhD, is the lead author of a new paper published in Drug and Alcohol Dependence titled "Daily patterns of substance use among young adults who vape nicotine and cannabis: Latent class analysis of smartphone-based daily diary data.”

 

Using 30 days of smartphone-based daily diaries from young adults who vape nicotine or cannabis, the study identified three distinct daily substance use patterns: nicotine-only vaping, nicotine and cannabis co-vaping, and combined combustible tobacco and cannabis use. Daily mood and cravings were linked to these patterns, with sadness predicting nicotine-only vaping days and stronger cannabis vaping cravings predicting co-vaping days. These findings suggest the need for interventions tailored to daily use behaviors.
