Scientists at University College London found that people who switched from regular to e-cigarettes or nicotine replacement therapy (NRT) for at least six months had ‘substantially’ lower levels of toxic and carcinogenic substances in their bodies.
During the study, which was funded by Cancer Research UK, researchers analysed the saliva and urine of long-term e-cigarette and NRT users and compared them to those of cigarette smokers.
They found that ex-smokers who switched to e-cigarettes or NRT had significantly lower levels of toxic chemicals and carcinogens in their body. They also found that those who used e-cigarettes or NRT while continuing to smoke did not experience the same reduction.
Dr Lion Shahab, the study’s lead author, said: ‘Our study adds to existing evidence showing that e-cigarettes and NRT are far safer than smoking, and suggests that there is a very low risk associated with their long-term use.
‘We’ve shown that the levels of toxic chemicals in the body from e-cigarettes are considerably lower than suggested in previous studies using simulated experiments. This means some doubts about the safety of e-cigarettes may be wrong.
