Question 1 of 24
How committed are you to the cigarette lifestyle?
The short answer
Long-term cigarette smoking is consistently associated with substantially shorter life expectancy in both cohort studies and modelling work. Widely reported UK research puts the cost at roughly 20 minutes of life per cigarette, and Global Burden of Disease modelling projects how smoking prevalence will shape years of life lost through to 2050.
Pick one to continue — the dead don't get to skip homework.
The cigarette, statistically speaking
💀 A grim little fact
Tobacco is the overachiever of the death industry: the World Health Organization pins more than 8 million deaths a year on it. Over 7 million are smokers; another 1.2 million are non-smokers who simply had the misfortune of sharing air with one.
A 2024 University College London study did the grim arithmetic and found a single cigarette shaves off about 20 minutes of life (17 for men, 22 for women). A pack? Roughly seven hours. Smoke a pack a day and you're basically pre-paying rent to Morty.
Tobacco: 8M+ deaths a year, the single most preventable cause of death on Earth.
🔮 Myth vs. Morty
You've heard "every cigarette costs you a minute." Cute — the real figure is closer to twenty. But here's the card the smoking uncle always plays: Jeanne Calment, the oldest verified human ever at 122 years, reportedly smoked for around 96 years and only quit near 117 (allegedly because she was too proud to ask someone to light it).
Morty's ruling: Jeanne is not proof smoking is safe — she's a walking, wheezing lesson in survivorship bias. For every Jeanne, millions of people quietly didn't make it to the punchline.

What the research shows
UK research estimated that each cigarette smoked cuts about 20 minutes off average life expectancy.

A Global Burden of Disease systematic analysis modelled how different smoking-prevalence scenarios would change years of life lost and life expectancy between 2022 and 2050.

What it does not show
These are statistical estimates from modelling and cohort comparison, not controlled experiments, and they remain open to confounding by the other things that cluster with smoking — diet, alcohol, and socioeconomic circumstances. The 20-minutes figure in particular is a population average derived from a model; it is not a stopwatch running on any individual smoker.
Every figure on this page describes a population, not a person. Associations measured across thousands of people cannot tell any individual how long they will live, and nothing here is medical advice. If something on this page concerns you, talk to a doctor rather than a comedy website.
