E-cigarettes ‘much safer than tobacco’

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.

Some previous studies suggesting that vaping is as harmful as smoking have little in common with real-world experience, it is claimed.

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).

Study participants who failed to make a clean break still had significant amounts of tobacco-related toxins in their saliva and urine.

Lead author Dr Lion Shahab, from University College London, 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.”

The Cancer Research UK-funded scientists studied 181 individuals including smokers and ex-smokers who had used e-cigarettes or NRT products such as patches and nasal sprays for at least six months.

A third group had continued to smoke at the same time as using e-cigarettes and NRT products.

Compared with full-time smokers, e-cigarette-only users had 97% lower levels of one toxic chemical, NNAL, that is strongly associated with lung cancer.

Alison Cox, director of cancer prevention at Cancer Research UK, said: “Around a third of tobacco-caused deaths are due to cancer, so we want to see many more of the UK’s 10 million smokers break their addiction.

“This study adds to growing evidence that e-cigarettes are a much safer alternative to tobacco and suggests the long-term effects of these products will be minimal.”
