That’s thanks to the cocktail of over 5,000 chemicals in cigarette smoke, of which at least 70 may cause cancer.
E-cigarettes, do not contain tobacco. Instead, they carry a nicotine-containing liquid which is heated into a vapour and inhaled.
The nicotine satisfies the cravings associated with addiction to cigarettes.
It’s not completely harmless but it doesn’t cause serious diseases like cancer – which tobacco does.
Since they arrived on the UK market e-cigarettes have become very popular.
There are now almost 3 million vapers in the UK, and more than half of them have completely stopped smoking tobacco.
A new Cancer Research UK-funded study shows that success rates for quitting smoking are at their highest level for a decade, and experts say e-cigarettes have made a big contribution.
And when smoking is still responsible for a fifth of all deaths in the UK, it’s great news that they are helping people quit.
But people still have a lot of questions around e-cigarettes.
Are they really safer than tobacco? Does second-hand e-cigarette vapour harm people like second-hand smoke? And are they leading kids into smoking tobacco?
