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.

Using prospective mixed methods to investigate the effect of the COVID‐19 pandemic on cannabis demand

Journal of the Experimental Analysis of Behavior, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 25, 2025

Following the COVID-19 pandemic, it is vital to understand how major global stressors influence substance use, including cannabis-related outcomes. The Marijuana Purchase Task assesses hypothetical cannabis demand (i.e., relative reinforcing value) and can detect contextual alterations. This study paired prospective assessment with qualitative inquiry explore impacted use behavior. Individuals previously enrolled in a laboratory administration opted remote follow-up survey (n = 41, 46% female). Participants were categorized as those who did or not increase based on self-reported changes flower provided explanations regarding pandemic-related influences General linear models repeated measures examined mean differences by occasion before/during COVID-19), group did/did use), their interaction.

Typical Hits, Grams, or Joints: Evaluating Cannabis Survey Measurement Strategies for Quantifying Consumption

Cannabis and Cannabinoid Research, Journal Year: 2022, Volume and Issue: 9(2), P. 646 - 658

Published: Dec. 28, 2022

Standardized survey measures that capture diverse cannabis consumption patterns are needed to inform public health and policy. Our team is developing a flexible, personalized, low-burden item inventory measure use estimate milligrams of THC (mgTHC) in large samples. This study aimed identify measurement gaps analysis implications associated with an initial pool candidate items assessed flower concentrate products (smoked and/or vaporized).

Exploring survey methods for measuring consumption quantities of cannabis flower and concentrate products

The American Journal of Drug and Alcohol Abuse, Journal Year: 2023, Volume and Issue: 49(6), P. 733 - 745

Published: Sept. 29, 2023

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.

Behavioral economic interactions between cannabis and alcohol purchasing: Associations with disordered use.

Experimental and Clinical Psychopharmacology, Journal Year: 2020, Volume and Issue: 30(2), P. 159 - 171

Published: Oct. 1, 2020

As cannabis policy changes, there is an urgent need to understand interactions between and alcohol couse. An online sample of 711 adult past-month users completed both single-item hypothetical purchasing tasks for cross-commodity assessing adjusting-price with concurrently available, fixed-price alcohol, vice versa. Participants provided information about use patterns, the Alcohol Cannabis Use Disorder Identification Tests (AUDIT CUDIT, respectively). Group data showed that served as complements (as price commodity increased, consumption commodities decreased). However, individual substantial variability nontrivial proportions showing patterns complementarity, substitution, independence. More negative slopes (greater complementarity) were associated greater self-reported drug CUDIT AUDIT scores. The relation cross-price slope CUDIT/AUDIT score indicates individuals who treat more are likely experience disordered use. Based on these data, when available at low prices, may be used high levels, whereas limiting one (e.g., through increased price) reduce other. These show importance examining participant analyses behavioral economic suggest manipulation cost taxes) or cosale restrictions potential public health regulatory mechanisms reducing couse behaviors.

Addiction, Journal Year: 2022, Volume and Issue: 118(4), P. 620 - 633

Published: Oct. 28, 2022

Abstract Background and aims The Marijuana Purchase Task (MPT) is increasingly used to measure cannabis reinforcing value has potential use for etiological regulatory research. This meta‐analysis sought evaluate the first time MPT's concurrent validity in relation involvement. Methods Electronic databases pre‐print repositories were searched MPT studies that examined cross‐sectional relationship between frequency quantity of use, problems, dependence, five indicators: intensity (i.e. unrestricted consumption), O max maximum P price at which demand becomes elastic), breakpoint consumption ceases), elasticity sensitivity rising costs). Random effects meta‐analyses effect sizes conducted, with Q tests examining differences by variables, meta‐regression test quantitative moderators, publication bias assessment. Moderators included sex, number prices, variable transformations, year publication. Populations community clinical samples. Results searches yielded 14 ( n = 4077, median % females: 44.8%: weighted average age 29.08 [SD 6.82]), published 2015 2022. Intensity, , showed most robust (| r 's| 0.147–325, p s < 0.014) largest significant | 0.325) dependence 0.320, 0.305, 0.303). Higher proportion males was associated increased estimates elasticity‐quantity ‐problems. prices significantly altered magnitude suggesting biased estimations if excessively low are considered. Methodological quality generally good, minimal evidence observed. Conclusions marijuana purchase task presents adequate demand, robustly intensity, elasticity. Moderating sex suggest potentially meaningful cannabis.

Cannabis demand and use among veterans: A prospective examination.

Psychology of Addictive Behaviors, Journal Year: 2023, Volume and Issue: 37(8), P. 985 - 995

Published: April 20, 2023

Cannabis demand (i.e., relative value), assessed cross-sectionally via a hypothetical marijuana purchase task (MPT), has been associated with use, problems, and dependence symptoms, among others. However, limited work exists on the prospective stability of MPT. Furthermore, cannabis veterans endorsing cyclical relationship between use over time, have yet to be investigated.
