Goldsmiths, University of London, London, UK.

Deaths related to drug 'misuse' remain at an all-time high in the United Kingdom (UK). Older heroin consumers are particularly at risk, with the highest rates of deaths among people aged 40-49 and the steepest rises in the over-fifty age bracket. Accordingly, a popular theory for the UK's increase in drug-related deaths, made by the government, and propelled in the media, is that there is an ageing cohort of heroin users with age-related health complications predisposing them to an overdose.

Effects of Implementation and Enforcement Differences in Prescription Drug Monitoring Programs in 3 States: Connecticut, Kentucky, and Wisconsin.

Subst Abuse 2021 25;15:1178221821992349. Epub 2021 Mar 25.

Institute for Health and Equity, Medical College of Wisconsin, Milwaukee, WI, USA.

Background And Aims: Prescription Drug Monitoring Programs (PDMPs) were designed to curb opioid misuse and diversion by tracking scheduled medications prescribed by medical providers and dispensed by pharmacies. The effects of PDMPs on opioid prescription, misuse and overdose rates have been mixed due in part to variability in states' PDMPs and difficulties measuring this complexity, and a lack of attention to implementation and enforcement of PDMP components. The current study uses qualitative interviews with key informants from 3 states with different PDMPs, Connecticut, Kentucky and Wisconsin to explore differences in the characteristics of the PDMPs in each state; how they are implemented, monitored and enforced; and unintended negative consequences of these programs.
