Abstrakt: People with trauma histories have an increased odds of cannabis use. Little is known about the frequency or consequences of different cannabis use regimens in cannabis users with trauma histories. Individuals with anxiety disorders tend to administer benzodiazepines in a pro re nata (PRN; i.e., as needed) as opposed to regularly scheduled (RS, e.g., twice daily [BID], three times daily [TID]) manner. Although physicians tend to prescribe benzodiazepines on a PRN regimen to minimize use, this regimen is paradoxically associated with greater use levels. Indeed, PRN administration regimens may increase use via negative reinforcement processes. We extended this older benzodiazepine literature to cannabis by examining regimen of cannabis use among 94 trauma-exposed cannabis users (mean age = 35.1 years; 52.1 % male; 23.4 % with cannabis prescription). Participants reported their initial and current cannabis use regimen (PRN vs. RS vs. both ['PRN+']) and their past month cannabis use frequency (use occasions in last month) and quantity (grams/use occasion). Consistent with patterns in benzodiazepine research, PRN (47.1 % of sample) and PRN+ (43.5 % of sample) were more common than RS regimens (9.4 % of sample). Also consistent with patterns seen with benzodiazepines, our sample moved toward PRN regimens from initial to current use: e.g., 100 % of initial RS users switched to a regimen that included PRN use. Consistent with predictions emerging from learning theory, PRN and PRN+ cannabis users reported significantly higher cannabis use frequencies compared to RS users (p's < 0.01). Unexpectedly, there were no significant differences between cannabis use regimen groups for quantity of cannabis/occasion. While limited by their cross-sectional nature, with longitudinal replication, result may have implications for identifying cannabis use regimens that minimize frequency of use and thereby reduce risk for negative health outcomes.
