Addiction Calculator
Estimate life expectancy reduction from alcohol, cigarettes, cocaine, meth, heroin, or methadone use patterns.
How This Addiction Calculator Works
This educational tool estimates how substance use may reduce life expectancy based on published per-dose time-loss statistics. It is not medical advice. For smoking-specific recovery, see the Cost of Smoking Calculator.
Estimation Method
$$\text{years lost} = \frac{\text{daily uses} \times 365 \times \text{years using} \times \text{hours lost per use}}{365 \times 24}$$
Frequently Asked Questions
How accurate is this estimate?
It is a population-level model. Individual genetics, health, and treatment change real outcomes.

Quitting can improve life expectancy. This model assumes continued lifelong use.
Why does country matter?
Baseline life expectancy varies by country and affects estimated years of use.
Which substance loses the most time per use?
Heroin has the highest modeled hours lost per use in this dataset.
Should I use this for treatment decisions?
No. Talk to a qualified healthcare provider for diagnosis and treatment planning.
