Measuring the quantity of marijuana flower use is challenging and there no standardized method measurement, yet it critical for cannabis researchers investigating its effects on health outcomes. We sought to identify frequency used per day, average size a joint, blunt or bowl, amount consumed hit. also examine distribution heavy daily in terms grams day. As part Marijuana Associated Planning Long-term Effects (MAPLE) longitudinal cohort study, an underrepresented, population persons with HIV (PWH), who were users (n = 253) (60.1% Age ≥50, 54.4% Male, 66.4% Black) completed retrospective, calendar-based timeline follow-back (TLFB) measure. Participants reported their grams, number hits dose, methods consumption during 30 days prior each study visit. Of 253 participants, 208 (82%) exclusively 52% daily, median 0.8 grams/day. The most common blunts (33%, 1.0 grams), joints (32%, 0.5 bowls (12%, 0.3 grams). hit was 0.063 grams. proportion had at least one day month, every month 30% 6% when defined as 3 grams/day, 43% 13% 2 59% 23% 1 gram/day. Our results this underrepresented PWH are similar others defining hit, joint healthy, young white, male populations. However, bowl smaller than commonly reported. Over half sample greater gram/day previous almost quarter gram month.

ABSTRACTBackground: Researchers need accurate measurements of cannabis consumption quantities to assess risks and benefits. Survey methods for measuring flower concentrate remain underdeveloped.Objective: We examined "grams" "hits" units quantities, calculating milligrams THC (mgTHC).Methods: Online survey participants (n = 2,381) reported preferred unit (hits or grams), past-week hits grams each product, product %THC. Quantile regression compared mgTHC between unit-preference subgroups. Hits-based calculations assumed a universal grams-per-hit ratio (GPHR). To examine individualized GPHRs, we tested "two-item approach," which divided total by hits, "one-item 0.5 responses the question: "How many would it take you finish 1/2 g your [product] [administration method]?"Results: Participants were primarily daily consumers (77%), 50% female sex, mean age 39.0 (SD 16.4), 85% White, 49% employed full-time. Compared those who unit, consuming more grams, higher %THC products, consequently, larger median (flower-hits mgTHC: 32 vs. 91 (95%CI: 52–67); flower-grams 27 113 73–95); concentrate-hits 29 59 15–43); concentrate-grams 61 129 43–94)). "Two-item" "one-item" approach GPHRs similar frequently smaller than GPHR.Conclusion: Allowing respondents choose when reporting does not compromise estimates. A low-burden, one-item yields "hit sizes" that may improve estimates.KEYWORDS: CannabismeasurementquantitysurveyTHC AcknowledgmentsWe like thank David Hammond, Ryan Vandrey, Tory Spindle, Marcel Bonn-Miller, Carrie Cuttler, LaTrice Montgomery, Adam Leventhal, this study.Disclosure statementDrs.
