Based on the most recent data from the World Health Organization, Euromonitor International, and independent public health surveys, the global number of adult vapers (e‑cigarette users) is projected to reach approximately 85–110 million by the end of 2025.

Current baseline (2023–2024): Around 80–95 million regular users.
Annual growth rate: Varies by region, averaging 5–8% globally, with faster uptake in Asia-Pacific and select emerging markets, offset by plateauing numbers in some Western countries.
Key uncertainty: Regulatory changes (bans, flavour restrictions) and evolving harm‑perception studies could slow or accelerate adoption in major markets.
This estimate covers all types of personal vapour devices. No single source provides a definitive real‑time census; the figure is a composite from sales data, household surveys, and industry reports.
