Are Two Oral-Fluid Collectors Interchangeable After Intranasal l-Methamphetamine?
A controlled 16-adult study found no significant differences on selected collector outcomes. Fixed collection order, low-volume samples and isomer-specific screening limit claims of equivalence.
-
Does 96% S-Methamphetamine Mean a Seized Sample Is 96% Pure?
A 19-sample seizure study measured total methamphetamine and relative isomer composition. Enantiomeric excess, S-isomer percentage and product purity use different denominators.
-
Did ADAPT-2 Randomize Methamphetamine Treatment Duration? Reading the Twelve-Week Analysis
A follow-up analysis modeled improvement through twelve weeks, including counterfactual placebo results for participants who switched treatment. It did not randomize stopping at six weeks against continuing.
-
Does an ADAPT-2 Subgroup Result Establish That Sexual Orientation Determines Treatment Response?
A secondary analysis found different medication effects between behavior-defined groups of men. The result requires prospective testing and does not establish an identity-based biological mechanism.
-
Do Seven Listed Pregnancy Programs Mean Seven Proven Methamphetamine Interventions?
An environmental scan identified seven programs, not seven controlled demonstrations of efficacy. Its search limits and lack of Indigenous-specific evaluations are central to interpreting the findings.
-
Does Shorter Newborn Withdrawal Treatment Prove Protection From Methamphetamine Co-Exposure?
A perinatal review shows why opioid type, mixed exposures and assessment methods matter. A shorter treatment course cannot establish that methamphetamine protected an infant.
-
What Does “Relapse” Mean in a Rat Methamphetamine Self-Administration Model?
A 2023 review links laboratory drug-seeking paradigms with molecular findings. Lever pressing, forced abstinence and punishment resistance are defined model outcomes, not individual human diagnoses.
-
What Can Methamphetamine Measurements in Fish Tell Us About Human Exposure?
A 2024 review describes waterborne exposure, tissue accumulation and behavioral findings in fish. It does not provide a human dietary-risk calculation or an impairment threshold.
-
Do Methamphetamine Treatment Benefits Persist After Incentives End? A Historical Review
A 2008 review distinguished gains during contingency management from evidence after incentives stopped. Mixed-stimulant samples and absent follow-up limit claims of durable methamphetamine-specific benefit.
-
Can Separate Methamphetamine Surveillance Systems Be Read as One Patient Journey?
A 2010–2019 analysis compared survey use, treatment admissions and overdose deaths across racial and ethnic groups. The unlinked systems cannot establish individual transitions or biological explanations for disparities.
-
Can Four Wastewater Campaigns Prove That Anti-Drug Measures Reduced Methamphetamine Use?
A two-city study estimated lower methamphetamine consumption late in 2019. Sparse sampling, population assumptions and the absence of a policy counterfactual limit causal attribution.
-
Does High Wastewater Removal Mean Methamphetamine Has Been Eliminated From the Environment?
An Iranian study measured large but variable changes across treatment plants and seasons. Parent-drug concentration removal is not proof of complete destruction or absence from receiving rivers.
-
Did Every Methamphetamine Dose Significantly Activate Glia in a Mouse Experiment?
A controlled mouse study found overall glial effects but few significant dose-by-time comparisons after correction. Behavior, dopamine markers and glial staining followed different timelines.
-
Did Improvement in Depression Explain the Methamphetamine Treatment Effect in ADAPT-2?
A secondary analysis linked early depressive-symptom improvement with later urine response. A modeled 24.8% mediated effect is not proof of a causal antidepressant pathway.
-
Can Early Urine Results Justify Stopping Bupropion Treatment for Methamphetamine Use?
A 55-person retrospective analysis predicted a combined abstinence-and-retention endpoint. It did not test whether switching treatment after an early positive result improved outcomes.
-
A Loss of 20–40 mg% Ethanol Is Not a Loss of 20–40 Percent
A historical blood-storage study reported losses in mg%, a concentration unit. Reading those figures as percentage losses changes their meaning and cannot support a universal correction.
-
Frozen Plasma Ethanol: Statistical Change Is Not the Same as Analytical Acceptability
An 80-sample plasma study found significant ethanol decreases at every tested interval, even though some group results met the authors’ chosen analytical tolerance.
-
Opened and Underfilled Blood Tubes: Why Ethanol Reanalysis Depends on Container History
Long-term testing of preserved antemortem blood found greater ethanol losses in opened and lower-volume tubes. Those results do not provide a universal correction for autopsy blood.
-
An Uninterpretable Postmortem CDT Result Is Not Evidence of Normal Drinking History
In one autopsy series, many CDT separations could not be interpreted. Analytical yield, diagnostic sensitivity and a negative result are different findings.
-
Does Postmortem CDT Change With Sampling Site or Delayed Autopsy?
A 70-autopsy study found no significant CDT differences across tested sites or delayed sampling, but many specimens were uninterpretable and diagnostic accuracy was not evaluated.
