Overall its prevalence seems to be trending down since it's emergence in Summer 2024, and peak in October. A year later, in August 2025 BTMPS was in about a quarter of fentanyl samples, and lower into September. āœŒšŸ¾ Buh bye, we hope.

This [article in *Vox*](https://www.vox.com/future-perfect/458272/alcohol-drinking-decline-health-teen-drinking-alcoholism) caught our attention because the decline in alcohol consumption corresponds with other drug use indicators among youth above. > In 2024, [according to one long-running youth survey](https://isr.umich.edu/news-events/news-releases/missing-rebound-youth-drug-use-defies-expectations-continues-historic-decline/), 42% of 12th graders reported drinking alcohol, down significantly from 75% in 1997\.

Corey Davis at the Network for Public Health Law has an [excellent lawyerly take](https://www.networkforphl.org/news-insights/the-july-2025-executive-order-and-the-state-of-harm-reduction-in-the-us/) on this and the Executive Order. Specifically, the letter notes "Opioid overdose reversal supplies, including the purchase of naloxone" -- which means all supplies needed to administer naloxone **including IM syringes**. [Intramuscular naloxone is really critical](https://remedyallianceftp.org/pages/all-about-naloxone) right now: It is the most cost effective and has the least side effects. Speaking of naloxone side effects, you'll want to read [this excellent qual paper](https://doi.org/10.1016/j.drugpo.2025.104948) led by Ranjani Paradise. Key takeaway is that giving too much naloxone has real consequences: "Many participants described intense physical pain and/or emotional distress immediately following overdose reversal, which reduced their desire and ability to engage with service providers." *Youā€™re so sick after that, \[treatment\] is the last thing on your mind, like, just donā€™t ask me anything, you know? ā€¦ Maybe the next day, youā€™d be up for thinking about \[treatment\] a little more, but usually not right after \[the overdose\].* As always, start with the minimum dose of naloxone, do rescue breathing, count breaths, and wait before doing a second dose. Titration using IM naloxone has long been used to reduce side effects, and is a skill participants should be comfortable with. --- # šŸ•µļø Research Update Lots of new data and scientific pubs on the drug supply: The brief upturn in overdose deaths we saw in late March and April 2025 in North Carolina had an [unexpectedly high level of cocaine](https://drive.google.com/drive/folders/1bEuitepfZNV6jFYA9YkYLXQ7fr2%5Fh7ts) involvement (42%) than usual (20-31%).

In the general population, [only 3.6% had purchased OTC naloxone](https://pmc.ncbi.nlm.nih.gov/articles/PMC12202286/). --- # šŸ˜µā€šŸ’« Hallucinations with medetomidine Adams just published [this open access paper](https://onlinelibrary.wiley.com/doi/10.1111/dar.70024) on a medical paradox: In hospitals, medetomidine is used to quell delirium. On the street, a community partner asked us to see if it could be causing hallucinations. Working with anesthesiologists, we found the same molecule(s) causing opposite effects in pharmaceutical versus unregulated forms. Since it was published, we have heard from paramedics, doctors, and harm reduction providers from the East Coast confirming that they too were seeing this. We want to emphasize that medetomidine remains predominantly a East Coast and Ohio River Valley contaminant. We are only seeing sporadic samples from the Southwest and West Coast.
