Abstract

fetched live from OpenAlex

Over the past 20 years, levels of Δ9-tetrahydrocannabinol (THC) in cannabis have significantly increased, while levels of cannabidiol (CBD) have increased much less in comparison. Cannabis with higher THC potency (commonly assessed via THC:CBD ratio) may increase the risk for cannabis dependence and trigger/exacerbate anxiety. However, few studies of cannabis potency effects on cannabis dependence and anxiety have examined gender moderation. Additionally, there are issues with how cannabis potency is calculated via the THC:CBD ratio that may contribute to inconsistencies in the literature. N = 202 (55.8 % women) recent cannabis users (>1 g in the past month) with trauma histories - a group at high risk for anxiety and cannabis dependence - completed an online survey including a self-report measure of THC and CBD levels in participants' typically-used cannabis product. Cannabis potency was calculated as THC:CBD ratio (THC%/CBD%) and as relative THC proportion (THC%/[THC%+CBD%]). Cannabis dependence and anxiety levels were self-reported on the Cannabis Use Disorder Identification Test-Revised (CUDIT-R) and Generalized Anxiety Disorder-7 (GAD-7), respectively. Consistent with prior findings in the general population, cannabis potency was significantly positively correlated with cannabis dependence, p = .002, and anxiety levels, p = .020, but only when assessed via THC proportion and not THC:CBD ratio. Consistent with prior research, women reported significantly higher anxiety levels but also unexpectedly, higher THC:CBD ratios, than men. No significant gender differences were found in the associations of either potency measure with either outcome variable. Results are consistent with recent reports of gender convergence in cannabis use prevalence. Additionally, these results identify relative THC proportion as a superior predictor of adverse cannabis and anxiety outcomes than the THC:CBD ratio in both men and women.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
