New research has dispelled reports that vaping could lead to deadly heart disease, after a test found that e-cigarettes do not cause damage to blood vessels. The same, however, cannot be said about regular cigarettes, as the test showed that cigarette smoke stops wound healing at concentrations over 20%. The study, administered by British American Tobacco, one of the largest tobacco companies in the world, found that even 100% vaper concentration with twice as much nicotine caused no disruption to skin repair. “Our results suggest that chemicals in cigarette smoke that inhibit wound healing are either absent from e-cigarette vapour or present in concentrations too low for us to detect an effect,” said Dr James Murphy, head of reduced risk substantiation at British American Tobacco. Smoking increases the risk of developing heart disease, the number one cause of death worldwide. It has been reported that e-cig regulation may damage a smoker’s health by putting people off quitting cigarettes. The scientists immersed lab-made endothelial cells in both smoke and vapour for 20 hours. The cigarette smoke concentration was between 0 and 30 per cent, whilst the vapour was between 40 and 100 per cent, which is double the nicotine. The research team concluded that the cigarette smoke had completely prevented the wound from healing, whilst the vapour had no effect, meaning there is no link between e-cigs and heart disease caused by damaged blood vessels. Debate rages on within the scientific community as to whether e-cigs are healthier than regular cigarettes.
