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",

    "assumptions": "Revised June 2026 to reflect the post-2023 reversal. Now uses 79,384 US drug overdose deaths in 2024 (CDC NCHS Data Brief 549, the latest complete year) against a roughly 260 million US adult population (18+, ~77% of the July 2024 resident total of 340.1 million). That yields an approximate adult-year hazard of 79,384 / 260,000,000 ≈ 0.000305 per adult-year. Compounded over 59 years of remaining adult life: 1 − (1 − 0.000305)^59 ≈ 0.0179, or about 1 in 56. This is down from the 1-in-42 figure built on the 2023 peak: the national age-adjusted rate fell 26.2% between 2023 and 2024 (31.3 → 23.1 per 100,000), the largest single-year decline NCHS has recorded, and 2025 provisional data project a further ~14% drop. The per-adult hazard remains higher than the per-capita hazard because deaths concentrate in working-age adults. 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. The uncertainty band reflects the open question of whether the 2024–2025 decline holds: the low bound (~1 in 63) applies the lower 2025 provisional count (~69,973 deaths) over the same 59-year horizon, while the high bound (~1 in 42) retains headroom for a rebound toward the 2023 peak level, since a single low year compounded over a lifetime should not be treated as locked in.\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-56 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. The 2023–2024 decline (the headline rate fell 26.2%) was also racially uneven: White and Black rates fell sharply — Black Americans saw the largest single-year drop (30.9%) — while American Indian and Alaska Native rates fell least (~20%) and remained the highest of any group at roughly 2.2× the national rate. So the overall improvement narrowed some gaps and widened others; the AI/AN disparity in particular persisted through the fourth-wave decline (CDC NCHS Data Brief 549, 2026). 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",
