    "description": "There is no canonical \"fear of dying from a drug overdose\" poll the way there is for flying or being murdered. Most people do not file overdose under \"things that could happen to me\" at all — it is mentally shelved alongside events that happen to other people, in other neighbourhoods, after other life trajectories. The gap between that intuition and the actual US lifetime number is one of the largest on this site.\n",

That yields an approximate adult-year hazard of 105,007 / 258,000,000 ≈ 0.000407 per adult-year. Compounded over 59 years of remaining adult life: 1 − (1 − 0.000407)^59 ≈ 0.0237, or about 1 in 42. The adjustment from the all-ages crude rate (~1 in 54 lifetime) reflects the fact that drug overdose deaths are concentrated in working-age adults, so the per-adult hazard is meaningfully higher than the per-capita hazard. Counts include all drug-involved overdoses — opioids, stimulants, benzodiazepines, and polysubstance — and are dominated by synthetic opioids (fentanyl) in the 2020s. Excludes pure alcohol poisoning (tracked separately) and excludes deaths coded as intentional self-harm by drug poisoning (ICD-10 X60–X64), which fall under suicide, not accidental/undetermined overdose.\n",

  "caveats": "This is the fear on Likelier where the pooled lifetime number is least informative about any individual reader's actual risk. The distribution is sharply skewed on three axes at once. By age, deaths are concentrated in the 25–54 band, with rates falling off steeply after 65 and near-zero in childhood. By drug exposure, the single biggest predictor is prior opioid use — people with no history of non-medical opioid or stimulant use carry a small fraction of the pooled hazard, while people with opioid use disorder carry many multiples of it. By geography, county-level overdose mortality spans more than an order of magnitude, with Appalachian, Rust Belt, and West Coast metros far above the national average. The 1-in-42 figure is the right answer to \"what is the average US adult's lifetime accidental overdose risk?\" and the wrong answer to almost any more specific question. Note also that Likelier's number excludes deaths coded as intentional self-harm by drug poisoning (those live under suicide) and excludes pure alcohol poisoning (separate category).\n",
