Modeling: youthful vaping barely affects life expectancy

According to a new American simulation, teenage vaping has a minimal impact on the lifelong risk of premature death.

The modeling study, published in the American Journal of Preventive Medicine, examined the lifelong health outcomes of approximately 4.1 million 12-year-old Americans in 2016 using a computer simulation. Researchers compared this to a hypothetical world without e-cigarettes, estimating the mortality risk of vaping at 5–30 percent of smoking, while also accounting for switching to smoking and later cessation.

Across the various conditions, the average cohort-level probability of premature death ranged from a 0.44 percentage point increase to a 0.06 percentage point decrease. This equated to a loss of no more than 31.3 days of life expectancy or a gain of up to 2.7 days. For those who exclusively vaped at age 20, the chance of premature death attributed to vaping ranged between 0.15 and 0.84 percent, compared to the 7–8 percent rate for smokers.

The authors highlighted the limitations of the model: the study did not cover non-fatal respiratory or cardiovascular diseases, the hypothetical risk estimates do not replace decades of follow-up data, and the simulation could not fully isolate the so-called gateway effect from the general propensity for nicotine consumption.

In Brief

  • A simulation of 4.1 million 12-year-old Americans suggests that youth vaping has a minimal impact on premature mortality.
  • For members of the cohort, the change in life expectancy ranged from a loss of at most 31.3 days to a gain of 2.7 days.
  • Among those who never smoked and only vaped at age 20, the probability of premature death was 0.15–0.84%, compared to 7–8% for smokers.
  • The model did not measure non-fatal illnesses, and the estimates do not replace long-term real-world clinical follow-up.
