Cigarette and vaping health calculator
See the body burden of nicotine, not the price tag.
This page estimates nicotine load, smoke-related oxygen loss, heart strain, sleep disruption, and daytime craving-loop pressure for cigarettes and common vape setups. Each health claim on the page points back to the reference directory below.[1][3][5][6][7][8]

Cigarettes, 2 cigs/day
Estimated daily health burden
27.6 min/day
This simplified comparison maps this routine to about 27.6 min/day, or roughly 7 days each year. Smoking also adds about 1.9% less room, +5.5 bpm resting-heart-rate pressure, and about 2.9 min less deep sleep on a repeating day.

Smoke vs vapor
Why this page treats smoking and vaping differently
The page separates what comes from nicotine itself from what specifically comes from burning tobacco.
Smoking adds smoke chemistry and carbon monoxide[1][2][6]
Burning tobacco adds carbon monoxide and many toxic chemicals on top of the nicotine. That is why cigarettes alone get the oxygen-carrying penalty on this page.
Vaping avoids burning, but not risk[3][4][7]
Vapes do not burn tobacco, so they avoid the smoke carbon-monoxide hit. But FDA and heart-health sources still describe aerosol as a meaningful exposure, not clean air.
Some outputs are model rules, not settled clinical law
The vaping absorption factors and the long-run life-impact range are fixed house assumptions chosen to keep this page transparent and comparable across product types.

2.4 mg/day
Daily nicotine dose = cigarettes/day x 1.20 mg
Why this matters
For cigarettes, the page uses about 1.2 mg absorbed nicotine per cigarette, which sits inside the common 1 to 2 mg range often used in public-health material. For vaping, the 70% and 55% factors are fixed house assumptions so the tool stays deterministic across very different puffing styles and device power levels.

1.9% oxygen hit
COHb % = min(14, 0.85 + 0.42 x cigarettes/day); oxygen hit = COHb % x 1.15
Why this matters
Cigarette smoke adds carbon monoxide, which binds to hemoglobin far more strongly than oxygen and leaves less room for oxygen transport. This page gives that smoke-only penalty to cigarettes, while vaping stays at the usual background carbon-monoxide level used in the supplied brief.
Calculation with your inputs
min(14, 0.85 + 0.42 x 2) = 1.7% COHb → 1.9% oxygen hit

RHR = min(20, 4.5 x ln(1 + daily nicotine dose)); HRV = -min(45, 8.5 x sqrt(daily nicotine dose)); stiffness = 6.2 x ln(1 + daily nicotine dose)
Why this matters
Nicotine can push the nervous system toward a more stimulated state. The formulas here turn that pattern into a simple estimate for heart-rate rise, lower recovery signal (HRV), and artery stiffness using the deterministic rules from your brief.
Calculation with your inputs
RHR = +5.5 bpm; body recovery dip = -13.2%; artery strain = +7.6%

Sleep onset = min(40, 4 x ln(1 + daily nicotine dose) + bedtime bonus); deep sleep = -min(35, 1.2 x daily nicotine dose); wake after sleep = min(45, 1.8 x daily nicotine dose)
Why this matters
Nicotine can delay sleep, cut into restorative deep sleep, and cause more waking after sleep starts. The exact caps on this page are fixed model rules so the estimate stays stable instead of pretending to know your exact sleep-lab result.

Sleep onset = +4.9 min; deep sleep = -2.9 min; night waking = +4.3 min

Daily life-loss equivalent = cigarettes/day x 13.8 min
Why this matters
This is a simplified comparison rule from the supplied brief, not a literal countdown clock. It turns long-run smoking harm into an easier daily comparison so cigarettes and vaping can be shown on the same page. The 5% to 10% vaping range is a cautious modeling assumption, not a settled clinical consensus.

Within 30 min → 60 min loop; 31-60 min → 75 min loop; after 60 min → 90 min loop
Why this matters
Earlier use after waking is often used as a marker of stronger dependence. This page turns that into a simple daytime loop estimate so the result stays understandable rather than pretending to diagnose addiction severity from a single answer.

Within 30 min → about every 60 minutes → roughly 16 daytime loops
