A study shows vaping or smoking reduces young adults' fitness by about 15 % compared to non-users.Summary
Researchers at Manchester Metropolitan University examined 75 healthy adults aged 18‑30, dividing them into never‑smoked/vaped, smokers, and vapers. Using incremental cycling tests, ultrasound, and blood markers, they found that both vaping and smoking lowered peak oxygen uptake and exercise capacity by roughly 15 %, increased breathlessness and leg fatigue, and caused vascular inflammation. The findings suggest vaping carries similar early cardiovascular and respiratory risks as smoking, supporting the UK’s Tobacco and Vapes Act 2026 and underscoring the need for further MRI studies to explore underlying mechanisms.
