The first long term study on the effects of quitting smoking by switching to vaping has been completed with resounding success.

Nicotine, Carcinogen, and Toxin Exposure in Long-Term E-Cigarette and Nicotine Replacement Therapy Users: A Cross-sectional Study has been conducted by a number of medical professionals including lead author, Dr Lion Shahab, from University College London.

The research was undertaken on 3 groups of people who smoked at the start of the survey; one group continued to smoke, one group switched to e-cigarettes only and the final group continued to smoke and also used e-cigarettes.

After six months, the participants who switched from smoking to vaping had far fewer cancer-causing substances and toxins present.

Levels of one of these toxic chemicals, NNAL – which is strongly associated with lung cancer – were 97% lower in those who switched to using just e-cigarettes compared to those who continued to smoke. Those who continued to smoke and also use e-cigarettes saw no difference in the level of NNAL in their body.

Not only were levels of NNAL drastically lower in the group who used e-cigarettes only, the number of volatile organic compounds (VOCs) was also reduced drastically in this group. Health professionals are confident that this proves vaping is far safer than smoking traditional cigarettes.

Dr Lion Shahab 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.

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.”

Study supported by Cancer Research UK

The study has been backed and funded by health experts, including Cancer research UK who also urge smokers to see through the bad press that perpetually surrounds vaping and to see the positive impact electronic cigarettes can have.

Cancer Research UK’s director of cancer prevention, Alison Cox said:

“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.”

The study, coupled with ITV’s coverage adds further weight behind Public Health England’s well-documented figure that vaping is 95% healthier than smoking.

Fraser Cropper, managing director of Totally Wicked LTD said:

“This is a very positive and credible study which yet again affirms the enormous potential these products have in supporting smoking cessation and risk reduction for smokers.  We continue to wait for the UK government to take a positive position and actively to encourage smokers to consider vaping.  If this and preceding body of academic evidence is not enough, then what is required for the UK government to stop equivocating and confusing the UK smoking population about the risks and benefits of vaping?”

We hope that this will be a milestone for vaping and should help to debunk the negative attitude peddled by the mainstream media, thus increasing people’s confidence in e-cigarettes and leading to millions of lives being saved.
