A recent study from Manchester Metropolitan University (MMU) has shed light on the detrimental effects of vaping and smoking on exercise capacity among young adults in the United Kingdom. The research, published in the ERJ Open Research journal, highlights that individuals aged 18 to 30 who vape or smoke exhibit similar reductions in fitness levels and increased breathlessness during physical activity.

The investigation involved 75 participants divided into three groups: non-smokers and non-vapers, smokers who had never vaped, and individuals who had vaped for approximately three years without ever smoking. All participants maintained comparable lifestyles, with similar levels of caffeine and alcohol consumption, as well as consistency in physical activity. This controlled setting aimed to ensure that the observed effects were directly attributed to vaping and smoking rather than extraneous lifestyle factors.
Dr. Azmy Faisal, a Senior Lecturer in Cardiorespiratory Physiology at MMU, stated that the research found a stark decrease in exercise capacity among active young adults who either vaped or smoked. Specifically, both groups displayed a reduction in fitness levels, approximately 15% lower than those who had never engaged in such activities. This alarming finding suggests that vaping is not merely a harmless alternative to smoking, as it manifests similar harmful changes to lung efficiency and blood vessel health during exercise.
To effectively measure fitness levels, participants underwent an incremental cycle exercise test, which assessed heart rate, breathing patterns, and blood lactate levels as they pushed their physical limits. The results revealed that both vaping and smoking were associated with noteworthy reductions in oxygen uptake, further corroborating their negative impact on fitness.
In addition to decreased fitness, the study revealed significant signs of inflammation in the blood vessels of both vapers and smokers. Such findings raise concerns about the long-term health implications of these habits, especially given the increasing prevalence of vaping among young people in the UK. The researchers noted that both groups experienced quicker accumulation of lactic acid during exercise, which led to heightened feelings of breathlessness and leg discomfort when compared with participants who had never used these products.
One of the primary implications of this research is its potential influence on public health policy and vaping regulations. Dr. Faisal emphasised the study’s importance for healthcare providers, the general public, and regulatory bodies, especially as more young adults choose to vape, often thinking it is a safer option than smoking. The findings provide crucial data regarding possible early health risks associated with vaping, which is particularly relevant in light of the upcoming Tobacco and Vapes Act 2026 in the UK.
This Act aims to enforce stricter regulations concerning vaping products, especially concerning their sale and use by young adults. As public health officials and lawmakers grapple with the rise in popularity of vaping, studies like this reinforce the need for robust regulatory frameworks to safeguard the health of future generations.
Furthermore, the study raises awareness about the underlying misconceptions surrounding vaping. Many young people may not realise that it can have detrimental effects similar to traditional smoking. As these products become ubiquitous in social settings, it is essential for educational campaigns to address the potential risks associated with their use.
In conclusion, the findings from this research underscore the pressing need for ongoing investigation into the health effects of vaping and smoking, particularly among young adults. As the UK prepares for tighter regulation of these products, the evidence provided by MMU’s study will likely play a significant role in shaping the conversation about youth health and wellness in the future.
