Unwanted effects, self-management strategies, and consequences of unwanted effects of methamphetamine use.
Article in Drug and alcohol dependence, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background Acute methamphetamine toxicities are poorly characterized. We sought to describe unwanted physical and mental effects from methamphetamine use, consequences of unwanted effects (e.g., altercations), and self-management strategies.
methodsWe used data from two cross-sectional surveys conducted from 2023 to 2024 in San Francisco and Oakland, CA (N = 1385), of people over 18 years of age who used unregulated drugs. Among participants reporting past 90-day methamphetamine use (n = 955), we determined the proportion with past 90-day unwanted effects; consequences of the most recent episode; and self-management strategies. We conducted bivariate analyses and multiple logistic regression analyses to identify predictors of unwanted effects.
resultsMedian age was 43 years, 73% were male, 40% White, 32% Black/African American, 18% Latine, 79% unhoused, with mean 18 of past 30 days methamphetamine use. Nineteen percent reported past 90-day unwanted effects of methamphetamine; independent predictors included Black or Latine race/ethnicity, prior mental health diagnoses, prior involuntary psychiatric hold, more days of methamphetamine use in the past 30 days, and longest stretch of methamphetamine use without sleeping. Among participants reporting unwanted effects, agitation, paranoia, or chest discomfort were most common; 52% reported consequences from unwanted effects, most commonly emergency department admissions; and 89% reported self-management strategies.
conclusionsApproximately one-fifth of participants regularly reported unwanted methamphetamine effects, associated with race/ethnicity, psychiatric history, and methamphetamine use parameters. Most had self-management strategies, yet more than half reported consequences from unwanted effects, including frequent emergency department admissions. Preventing and managing these toxicities requires distinct strategies compared to other substances like opioids.
