Workplace Drug Testing—Prevalence of Positive Test Results, Most Common Substances, and Importance of Medical Review

Drug Testing and Analysis, EarlyView.
Among 23,900 urine and oral fluid drug tests from Swedish workplaces, 4.6% tested positive for controlled substances. Cannabis, amphetamine, cocaine and benzodiazepines were most common. Many samples containing opiates, amphetamine or benzodiazepines were MRO verified as being due to medical prescriptions, while cannabis or cocaine were almost entirely

Screening and Quantification of the Synthetic Cannabinoid Receptor Agonist 5F‐MDMB‐PINACA From Seized Prison Paper Using Ultraperformance Liquid Chromatography–Mass Spectrometry Approaches

Drug Testing and Analysis, EarlyView.
Synthetic cannabinoid receptor agonists are being infused on paper and illicitly introduced into prisons through mail correspondence. An approach to quantify and map the synthetic cannabinoid 5F‐ADB on a seized paper sample from a UK prison was determined using ultraperformance liquid chromatography–quadrupole Dalton–mass spectrometry.

Effects of Dimenhydrinate on Motor Behavior and Vascular Function: Possible Implications for the Field of Sports

Drug Testing and Analysis, EarlyView.
Regarding cardiovascular effects, DMH decreased vascular reactivity to phenylephrine and acetylcholine. We observed that the combination of DPH and 8‐Cl‐T was identified as the responsible for increasing blood pressure and heart rate in the biological model used.
