A preliminary investigation of tobacco co-use on endocannabinoid activity in people with 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
Tobacco is commonly co-used with cannabis. This is unfortunate because tobacco co-use exacerbates select clinical consequences associated with cannabis use. Evidence demonstrates that low levels of anandamide, a prominent endocannabinoid, correlate with worse clinical outcomes. Fatty acid amide hydrolase (FAAH) degrades anandamide, and greater FAAH levels may underlie poorer clinical outcomes in people who co-use relative to those who use only cannabis. Therefore, we tested whether tobacco co-use increases FAAH levels beyond those associated with cannabis use alone. Cannabis-using participants (N = 13) were parsed into individuals with daily tobacco use (CT, n = 5) and no current tobacco use (CAN, n = 8). We evaluated group differences in FAAH, quantified using positron emission tomography and [
