abstract="BACKGROUND: Cannabis demand (i.e., relative value) is usually assessed as a trait-level risk-factor for cannabis use and consequences. This study examined within-person variability in day-level intensity (i.e., amount consumed at zero cost) and O(max) (i.e., maximum cannabis expenditure) and tested hypotheses that demand would be positively associated with day-level cannabis use. <br><br>METHODS: Young adults (n=85) reporting past-month simultaneous alcohol and cannabis use completed two daily surveys for 30 days. Morning surveys assessed prior-day cannabis use and evening surveys assessed day-level demand (i.e., intensity, O(max)). Multilevel models tested day-level effects of intensity and O(max) on any cannabis use and flower use frequency and quantity (i.e., grams). <br><br>RESULTS: Approximately 52 % and 46 % of variability in intensity and O(max), respectively, was due to within-person change. At the day-level, higher intensity and O(max) were associated with higher likelihood of any cannabis use, regardless of formulation; O(max) was associated with use of flower in particular; and intensity was associated with the highest quantity of use. At the person-level, only O(max) was associated with flower use likelihood, and only intensity was associated with flower quantity across days. <br><br>CONCLUSIONS: Cannabis demand demonstrated day-to-day variability, conceivably in response to various internal states and external factors. Intensity and O(max) were related to elevated likelihood of using any cannabis, particularly flower, at the day-level. Overall, these data illustrate the validity and utility of brief cannabis demand measures, which might be used to further understand cannabis' reinforcing value at a fine-grained level.<p /> <p>Language: en</p>",
