1. 27 July 2026 · corrected by Emir Baycan

   Fact-check: corrected the JAMA study year (2014), Purdue settlement figure ($7.4B), buprenorphine prescriber scope (any DEA-registered practitioner), the RCT-vs-observational basis for methadone mortality evidence, the 2021 synthetic-opioid death count (70,601), and several overbroad claims about fentanyl distribution and heroin market share.

   Before

   2012 JAMA study; Purdue settlements ~$6B; buprenorphine by any licensed physician; >50 RCTs show methadone reduces overdose mortality ~50%; fentanyl distributed into all drug supplies; ~80,000+ synthetic-opioid deaths by 2021; all three MOUD medications consistently reduce mortality; by 2016 the majority of heroin nationally was fentanyl.

   After

   2014 JAMA study (Cicero et al.); Purdue plan later approved at ~$7.4B (pledged, not distributed); buprenorphine by any DEA-registered practitioner (NPs/PAs incl.); RCTs establish methadone efficacy/retention while observational cohorts show ~50% mortality reduction; fentanyl found in heroin, counterfeit pills and other supplies; 70,601 synthetic-opioid (non-methadone) deaths in 2021; mortality evidence strongest for methadone/buprenorphine; regional 2016 fentanyl prevalence, national share uncertain.

   Why: Independent fact-check against CDC/NCHS, JAMA Psychiatry (2014), NY AG (2025 Purdue plan), and the MAT Act 2022: corrected a citation year, an outdated settlement figure, a prescriber-scope error, an evidence-characterization error, a death-count metric, and several overbroad claims.

   Corrected multiple factual errors on When Notes Fly's opioid crisis explainer: an incorrect date, an incorrect cumulative death toll, an unverifiable direct quote, and an overbroad claim about safe-injection-site outcomes that was only true of one specific site.

   Before

   Blockquote: "We did this systematically, as a matter of policy and profit." - Patrick Radden Keefe, Empire of Pain (2021). Article gave no cumulative US opioid death toll and no date for the first sanctioned US supervised-consumption site, and generalized supervised-consumption outcomes broadly rather than to the specific site studied.

   After

   Removed the unverifiable direct-quote attribution to Patrick Radden Keefe (de-quoted to a paraphrase framing). Added the real cumulative figure: more than 645,000 US opioid-involved overdose deaths 1999-2021 (CDC/NCHS National Vital Statistics System). Added the real date the first officially sanctioned US supervised consumption sites (OnPoint NYC, Washington Heights and East Harlem) began operating: November 30, 2021. Narrowed an overbroad claim about supervised-consumption-site outcomes to what the cited 2011 Lancet study actually found for Vancouver's Insite (35% reduction in overdose mortality in the surrounding area).

   Why: Fixed in the body, the FAQ, and the excerpt: an unverifiable direct quote presented in quotation marks, a missing cumulative death-toll statistic, a missing/wrong date for the first US supervised consumption site, and a claim generalized beyond what the cited study supported.
