Typical 24 Hours
The interactive 24-hour curve loads with the live model.
This curve shows a typical modelled day, not historical observations.
How this vaping estimate works
Σ (region population × participation × local-hour probability)
Keep the existing 100-million user pool, eleven assumed daily episodes and 1.2-minute assumed episode duration. Their product divided by 1440 is the average simultaneous episode count. UN population shares allocate the pool; the existing local day/evening curve shapes it. Weekly variation remains neutral because no matched global weekly schedule is available.
What the number means
How many people are vaping right now? See a WHO user-pool-based simulation with clearly separated assumptions about use episodes and local time. Health, age, access and reporting differences make the real total uncertain. The number is a broad modelled estimate, not direct tracking of individuals.
This estimate is for curiosity and perspective. Activities can overlap, and the totals should not be added together as if every category were exclusive.
Assumptions and limitations
A floor on users is not a lower confidence bound on concurrent vaping: the assumed episode frequency could be too high or too low. Prevalence varies sharply by country, age and regulation. Country populations and civil clocks are source-based; country behaviour is not observed live. Survey values are transferred only as explicit proxies. The displayed range is editorial sensitivity, not a statistical confidence interval.
Source scope and reference years
- WHO — Global tobacco trends 2025 (2025): Over 100 million e-cigarette users. Use 100 million only as an anchor floor, not exact prevalence.
Direct answers
Questions people ask
How many people use e-cigarettes worldwide?
WHO reported more than 100 million users in 2025. The model retains 100 million as a conservative user-pool anchor; it is not an exact current census.
Does 100 million users mean 100 million vaping now?
No. The concurrent model assumes eleven 1.2-minute episodes per user per day, then distributes that time across local hours. Those episode values are modelling assumptions, not WHO findings.
Is this an estimate of vaping health risks?
No. The counter models activity time, not health outcomes, exposure dose, medical advice or product safety.
What changes this estimate?
The published user pool anchors scale, while episode length and frequency determine concurrent use. Countries have very different prevalence and regulations; population allocation does not capture those differences.
This estimate represents people in an assumed e-cigarette-use episode. It is not the number who own a device, vape at least once a year or use every kind of tobacco.
