Detox timeline calculators estimate how long a substance takes to clear from the body based on its biological half-life — the time for plasma concentration to halve. Full clearance is approximately 5 half-lives.
단계별 가이드
- 1Full clearance ≈ 5 × half-life
- 2Caffeine: half-life 5–6 hours; fully cleared in ~30 hours
- 3Nicotine: half-life ~2 hours (cotinine 16–20 hours)
- 4Alcohol: metabolised at ~0.015% BAC/hr (15mg/100mL/hr) linearly — not exponential
