Fentanyl 5 microg (as the citrate) per milliliter in 0.9% sodium chloride injection, packaged in polypropylene syringes and stored protected from light, was stable for at least 90 days in controlled ambient conditions.

To evaluate trends related to accidental overdose deaths in Oklahoma, with a focus on opioids and methamphetamine. All accidental drug overdose deaths in the state of Oklahoma from 2002 to 2017 were reviewed. Opioids were grouped into the following categories: all opioids, prescription opioids, synthetic opioids, and heroin. Age-adjusted death rates for methamphetamine and each opioid category were calculated and analyzed. Accidental overdoses accounted for 9,936 deaths during the study period. Of these, opioids were seen in 62.9%, with prescription opioids comprising 53.8%, synthetic opioids 10.3%, and heroin 2.8%. Synthetic opioids, despite a recent upward nationwide trend, showed a slight overall decrease (−6.8%) from 2009 to 2017. In contrast, methamphetamine showed a 402.2% increase from 2009 to 2017, and an overall increase of 1,526.7%. Methamphetamine was involved in the most overdoses (1,963), followed by oxycodone (1,724). Opioid-related deaths were most common amongst white individuals (90.3%) and showed a slight male predilection (56.9%). With the intent of assessing the opioid epidemic as it relates to accidental overdoses in Oklahoma, this study suggests that opioid-related overdoses have slowed in recent years amidst a sharp increase in methamphetamine deaths.

The focus of this study was to determine the stability of four synthetic cannabinoids, XLR-11, UR-144, AB-Pinaca and AB-Fubinaca in biological specimens for the purpose of casework processing prioritization. The study used human whole blood spiked with the compounds of interest to mimic real forensic laboratory samples submitted for synthetic cannabinoid analysis. The spiked whole blood specimens were incubated under one of three temperature conditions: room or ambient (22°C), refrigerated (4°C) and frozen (-20°C) for a period of 12 weeks. Study specimens were then extracted using a forward alkaline extraction at pH 10.2 and analyzed using a liquid chromatograph tandem mass spectrometer (LC-MS-MS). Under all incubation conditions results showed that AB-Fubinaca, AB-Pinaca and UR-144 were relatively stable while XLR-11 significantly degraded at ambient and refrigerated conditions. Frozen storage conditions were the only tested parameter able to preserve and stabilize all four compounds over the three month period. Therefore, it should be suggested that forensic blood evidence suspected of containing synthetic cannabinoid compounds should be stored in frozen conditions.

A 6-year-old male child was scheduled for a dental procedure requiring conscious sedation. Prior to the procedure, the child was administered a dental cocktail containing chloral hydrate, hydroxyzine, and methadone. After returning from the dentist, the child appeared groggy and was allowed to sleep. A few hours later, he was found unresponsive, and following resuscitation attempts at a local medical center, he was pronounced dead. Toxicological analyses of femoral blood indicated the presence of hydroxyzine at less than 0.54 μg/mL, trichloroethanol (TCE) at 8.3 μg/mL, and methadone at 0.51 μg/mL. No meperidine was detected. The cause of death was reported to be due to the toxic effects of methadone. The toxicological analysis was corroborated by the analysis of the contents of the dental cocktail, which revealed the presence of hydroxyzine, chloral hydrate, and methadone. Residue from a control sample obtained from the same pharmacy, but administered to a different subject, was found to contain hydroxyzine, chloral hydrate, and meperidine. This report represents the first known fatality due to accidental substitution of methadone in a dental cocktail.
