The difference between how smoking and vaping affects your body is astounding.
A video has been released demonstrating how the toxic chemicals and tar that are inhaled by an average smoker in just one month compares with those that do not smoke or use an e-cigarette.
Public Health England (PHE) shared the footage from an experiment to show the devastating harm that is caused to the body by smoking and how it can be avoided by switching to vaping.
Research shows that close to half of smokers either don't realise that vaping has much lower risks to health or wrongly believe that vaping is as harmful as smoking.
As reported by Wales Online, at least 500,000 smokers are expected to try to stop smoking and PHE are encouraging those who do to use its Personal Quit Plan to increase their chances.
The film features health experts Dr Lion Shahab and Dr Rosemary Leonard carrying out an experiment to visually demonstrate the high levels of cancer-causing chemicals and tar inhaled by an average smoker over a month compared with not smoking or using an e-cigarette.

The experiment mimics the effects of inhaling tobacco smoke, e-cigarette vape and normal air into the lungs, with the lungs represented by three bell jars filled with cotton wool.
Each bell jar is attached to a diaphragm pump providing a continual and equal draw of air through each bell jar - one set up to "smoke" tobacco cigarettes, another to "vape" e-cigarettes and the third used as the control with only air drawn through it.
What were the results?
By the end of the experiment, the cotton wool in the tobacco bell jar is brown, the inside of the bell jar is brown and the tube leading to the air pump is thick with tar.
In comparison, the cotton wool in the e-cigarette bell jar remains practically unchanged, with some water vapour on it and very slight discolouration from the colouring in the e-liquid.
The inside of the bell jar had a few droplets of water vapour, while the "control" bell jar is entirely unchanged.
Research estimates that, while not risk-free, vaping is at least 95 per cent less harmful than smoking.
PHE director of health improvement, Professor John Newton, said: "It would be tragic if thousands of smokers who could quit with the help of an e-cigarette are being put off due to false fears about safety. We need to reassure smokers that switching to an e-cigarette would be much less harmful than smoking."
Smoking increases the risk of developing more than 50 serious health conditions, including cancer and heart disease, and doubles the risk of dying from a stroke. These are the signs and symptoms of the most common cancers that you should not ignore.
