Positive Doping Test Linked to Crumb Rubber From Artificial Football Pitch: Case Report

Drug Testing and Analysis, Volume 18, Issue 6, Page 719-724, June 2026.
1,3‐DMBA was detected in urine samples of eight athletes following a doping control, resulting in one AAF and levels below WADA's MRL in seven teammates. Investigation revealed contamination from rubber infill used on the indoor artificial turf, with analysis confirming 1,3‐DMBA in the turf's crumb rubber originating from recycled tires.

In Vivo and In Vitro Evaluation of PTeCA (1H‐Pyrrole‐2,3,4,5‐Tetracarboxylic Acid) in Hair Matrix as a Marker for Oxidative Cosmetic Treatment

Drug Testing and Analysis, Volume 18, Issue 6, Page 739-749, June 2026.
A total of 3378 self‐reported treated and untreated hair samples were analyzed for PTCA and PTeCA by LC‐MS/MS. Moreover, their in vitro formation was assessed in 225 untreated hair by different cosmetic treatments with and without oxidative agents. Data suggest that PTeCA could be a reliable marker for oxidative cosmetic treatments in hair.

Chemical Straightening as a Source of Analytical Variability in Hair Testing: A Dual‐Analyte Case Report

Drug Testing and Analysis, Volume 18, Issue 6, Page 771-776, June 2026.
Permanent chemical hair straightening was associated with analyte‐dependent changes in hair concentrations, showing increased endogenous GHB levels and decreased alprazolam concentrations after treatment. These results suggest that chemical hair straightening procedures may influence hair concentrations and should be considered when interpreting hair ...

Influence of Different Washing Hair Procedures in the Quantitative Determination of THC and THCCOOH

Drug Testing and Analysis, Volume 18, Issue 6, Page 777-784, June 2026.
Different hair decontamination protocols significantly affect THC quantification, with marked analyte loss—particularly after aqueous‐organic washing—whereas THCCOOH remains stable. These findings highlight the risk of misinterpretation and the need for standardized washing procedures in hair analysis.

Cannabidiol Protects Against 1‐Methyl‐4‐Phenylpyridinium and Manganese‐Induced Neurotoxicity via Nod‐Like Receptor Protein 3 Inflammasome Suppression

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
CBD oil exhibits neuroprotective effects in Parkinson's disease models by inhibiting NLRP3 inflammasome activation. It preserves dopamine levels and reduces α‐synuclein accumulation, suggesting its potential as a therapeutic strategy against neuroinflammation and neurodegeneration.

AB‐MDMSBA—Not a Synthetic Cannabinoid Receptor Agonist

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
This study uses classical in vitro pharmacology approaches to establish that AB‐MDMSBA does not bind to or activate the cannabinoid CB1 receptor and therefore should not be classified as a synthetic cannabinoid receptor agonist. ABSTRACT Synthetic cannabinoids remain one of the most prominent classes of New Psychoactive Substances (NPS).

Blood Lead Levels in Adults and Children of East Otago Communities, New Zealand: Findings From a Public Health Response to Lead Detected in Drinking Water

Public Health Challenges, Volume 5, Issue 2, June 2026.
Blood lead levels (BLLs) in East Otago adults and children were similar to prior New Zealand estimates, with no consistent evidence of elevation in the exposed population. BLLs were higher than comparable high‐income countries, likely reflecting exposure from known sources. Ongoing public health action is required to reduce lead exposure.
