Using ecological momentary assessment to quantify Δ-9-tetrahydrocannabinol and cannabidiol use across different forms of cannabis: Feasibility in a sample of Canadian young adults reporting frequent cannabis use.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsTo establish the feasibility of using ecological momentary assessment (EMA) to estimate total quantities of Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) used across different forms of cannabis, and to assess the predictive validity of THC estimates for predicting acute cannabis-related consequences.

participantsTargeted sample of n = 42 young adults (59.52% women, mean age 25 years) reporting frequent cannabis use. MEASUREMENTS: Surveys completed immediately prior to cannabis use assessed the quantities, THC content and CBD content of various forms of cannabis to be used in the current session; participants also uploaded photos of the cannabis product labels when available. Surveys administered at fixed times throughout the day (84.81% completion rate) assessed acute cannabis-related consequences.
findingsParticipants completed a total of 786 pre-cannabis surveys, of which 79.39% and 77.35% contained sufficient information to calculate total THC and CBD (in milligrams), respectively. High agreement was observed between participant-entered THC and CBD contents and those shown in corresponding photos of cannabis product labels. Aggregating across all products used, participants reported using an average of 141.41 [standard deviation (SD) = 224.62, range = 0.00-2000.00] milligrams of THC (i.e. 28.28 standard five-milligram units) and 7.53 (SD = 34.87, range = 0.00-484.22) milligrams of CBD per day. Multilevel models revealed that participants were more likely to report acute negative consequences following sessions when their estimated THC use was higher than their typical THC use. At the between-person level, participants reporting more THC use on average across sessions were less likely to report negative consequences overall.
conclusionsUsing ecological momentary assessment to estimate total quantities of Δ-9-tetrahydrocannabinol and cannabidiol used across different forms of cannabis appears to be feasible, with preliminary predictive validity for acute negative cannabis-related consequences.
