Momentary Craving, Craving Variability, and Cannabis Use: Associations With THC Concentrates and Sex.

OBJECTIVE

Ecological momentary assessment (EMA) studies are well positioned to assess the impact of craving on cannabis use in real time and may better capture its time-varying nature. The goal of this exploratory study was to examine whether momentary craving and craving variability predict subsequent use of cannabis and how baseline concentrate use status and male sex might affect these relationships.

METHOD

College students residing in a state with legal recreational cannabis use who used cannabis twice a week or more completed a baseline interview and signal-contingent EMA for 2 weeks using a smartphone application. Hierarchical (multi-level) regression was used to examine time-lagged associations between craving, craving variability, and subsequent cannabis use. Baseline concentrate use and male sex were examined as moderators.

RESULTS

Participants ( = 109) included 59% women, with an average age of 20.2 years, and most using cannabis near-daily or daily. A main effect for craving (within-level effect) on the likelihood of cannabis use at the next EMA instance was found (odds ratio = 1.292, < .001), although this effect was moderated by concentrate use status. For men, between-level increases in craving led to a greater likelihood of cannabis use at the next instance, but greater craving variability led to a lower likelihood of use. Greater variability in craving was associated with a greater likelihood of cannabis use among those using concentrates.

CONCLUSIONS

The experience of craving may differ based on important participant characteristics. More research examining the fluctuating nature of craving and the role of cannabis potency on craving is warranted.
