Opioid overdose deaths in the United States quadrupled from 1999 (n = 8050 deaths) to 2015 (n = 33 091 deaths), and the number of deaths associated with synthetic opioids, such as fentanyl, increased from 3105 deaths in 2013 to nearly 20 000 deaths in 2016. Given this rapid increase, timely surveillance for drugs in circulation is crucial. However, current surveillance systems used to track drug overdoses do not detect new drugs in circulation quickly. We studied the change in the presence of fentanyl in "stamp bag" drug evidence in Allegheny County, Pennsylvania, from 2010 through 2016. Stamp bags are small wax packets with individual stamps that contain mixtures of drugs, most commonly heroin, that law enforcement officers seize and retain as legal evidence. The proportion of stamp bags determined to contain fentanyl or a fentanyl analog was 2.1% in 2014 and rose sharply to 17.1% in 2016. Monitoring the chemical makeup of drug evidence items could help public health authorities identify drug use trends in their jurisdictions.

Background: Drug overdose mortality is a major public health concern in the United States, with prescription opioids contributing substantially to recent increases in drug overdose deaths. Compared to unintentional drug overdose deaths, relatively little data describes intentional self-inflicted drug overdose deaths (i.e., suicide by drug overdose). The aim of this study was to examine the characteristics of self-inflicted drug overdose deaths, overall and in comparison to unintentional drug overdose deaths., Methods: We linked vital statistics, prescription drug monitoring program, and toxicology data for self-inflicted and unintentional drug overdose deaths among North Carolina residents in 2012., Results: Most self-inflicted (79.2%) and unintentional (75.6%) drug overdose decedents had a prescription for a controlled substance within one year of death. Toxicology results revealed that antidepressants contributed to a significantly higher percent of self-inflicted compared to unintentional drug overdose deaths (45.0% vs. 8.1%). Among deaths in which commonly prescribed opioids (oxycodone, hydrocodone) or benzodiazepines (alprazolam, clonazepam) contributed to death, a significantly higher percent of self-inflicted drug overdose decedents had a prescription for the substance within 30days of death compared to unintentional drug overdose decedents., Conclusions: The results highlight the use of prescription opioids, benzodiazepines, and antidepressants among self-inflicted drug overdose decedents. Importantly, the results indicate that self-inflicted drug overdose decedents were more likely than unintentional drug overdose decedents to have potential contact with the health care system in the weeks preceding death, offering an opportunity for professionals to identify and intervene on risk factors or signs of distress and potential for self-harm., (Copyright © 2017 Elsevier B.V.

Background: In the United States, overdose mortality from controlled substances has increased over the last two decades, largely involving prescription opioid analgesics. Recently, there has been speculation on a transition away from prescription opioid use toward heroin, however the impact on overdose deaths has not been evaluated., Methods: Time series study of North Carolina residents, 2007 through 2013. Monthly ratio of prescription opioid-to-heroin overdose deaths. Non-parametric local regression models used to ascertain temporal shifts from overdoses involving prescription opioids to heroin., Results: There were 4332 overdose deaths involving prescription opioids, and 455 involving heroin, including 44 where both were involved (total n = 4743). A gradual 6-year shift toward increasing heroin deaths was observed. In January, 2007, for one heroin death there were 16 opioid analgesic deaths; in December, 2013 there were 3 prescription opioid deaths for each heroin death. The transition to heroin appears to have started prior to the introduction of tamper-resistant opioid analgesics. The age of death among heroin decedents shifted toward younger adults. Most heroin and opioid analgesic deaths occurred in metropolitan areas, with little change between 2007 and 2013., Conclusions: The observed increases in heroin overdose deaths can no longer be considered speculation. Deaths among younger adults were noted to have increased in particular, suggesting new directions for targeting interventions. More research beyond vital statistics is needed to understand the root causes of the shift from prescription opioids to heroin., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)
