A land mark study carried out by the University College London and funded by Cancer Research UK has found Vaping to be ‘far safer than smoking’

The study undertaken by 181 smokers or ex-smokers looked at the changes that took place to each individual after they switched to vaping. Measurements of various toxins and cancer causing carcinogens where recorded after the volunteers started vaping and stopped smoking tobacco products.

Once completed the study’s conclusion was that vaping is far safer than smoking.

This is one of the first studies to be undertaken outside of a laboratory so the results are much more accurate in terms of what happens in the ‘real world’.

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.

"Understanding and communicating the benefits of nicotine replacements, such as e-cigarettes, is an important step towards reducing the number of tobacco-related deaths here in the UK."

Each of the 181 volunteers undertook a detailed questionnaire and gave saliva, breath, and urine samples. The results showed significantly lower levels of cancer-causing substances and toxic chemicals in the samples of the volunteers who had already been using electronic cigarettes or nicotine replacement therapy (NRT)

An un expected result showed that for the people in the study called ‘combined users’ who had been trying to give up smoking by using both traditional cigarettes and a vaping device their toxic and carcinogen levels remained very high, and like that of a full smoker.

One of the researchers Robert West said E-cigarettes are likely to be beneficial only if complete cessation of combustible cigarette smoking is achieved. Thus, dual users should be encouraged to cease using combustible products to reduce long-term health risks.”

The test which took 6 months to complete aimed to assess the various effects on long term vaping or the use of NRT It compared

  • current smokers of cigarettes only
  • former smokers using e-cigarettes-only or NRT-only
  • combination smokers – cigarette smokers also using an e-cigarette or NRT

Overall the results are very positive in the favour of vaping. They conclude that former smokers who have now switched to vaping have significantly lower levels, in fact 97% lower levels of cancer causing chemical NNAL than that of smokers.

University College London’s lead author, Dr Lion Shahab said: “Our study adds to existing evidence showing that e-cigarettes and nicotine replacement therapy 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.”

Dr Lion also added: “This means some doubts about the safety of e-cigarettes may be wrong. Our results also suggest that while e-cigarettes are not only safer the amount of nicotine they provide is not noticeably different to conventional cigarettes. This can help people to stop smoking altogether by dealing with their cravings in a safer way.”
