E-cigarettes are far safer than tobacco, says study
Vaping has been given an emphatic thumbs up by health experts after the first long-term study of its effects in ex-smokers.
After six months, people who switched from real to e-cigarettes had far fewer toxins and cancer-causing substances in their bodies than continual smokers, scientists found.
Nicotine patches also appeared to be far safer than tobacco products, according to the analysis of saliva and urine samples.
Experts hope the findings will reassure would-be quitters who have been confused by mixed messages about the safety of e-cigarettes.
The new findings also show that to be safe it is necessary for smokers to switch over completely to e-cigarettes or nicotine replacement therapy (NRT).
Lead report author Dr Lion Shahab, from University College of London, said: "Our study adds to the existing evidence showing that e-cigarettes and NRT are much safer than smoking, and suggests that there is a very low risk associated with their long-term use."
