What is vaping?
Vaping means using an e-cigarette or vaping device. Both have a heating element that converts liquid into vapor which you then inhale. Vaping liquid comes in many different flavors and nicotine strengths; some have no nicotine at all.
Is it dangerous?
Research has shown that vaping is 95% less harmful than smoking tobacco cigarettes. While much safer than cigarettes, there are still some concerns. Vaping is less harmful than smoking. Many of the toxic and cancer-causing chemicals in tobacco and the tobacco smoke form when tobacco is burned.   
Nicotine is not known to cause cancer. It is approved for use in nicotine replacement therapies, such as the patch or nicotine gum. However, there are risks linked to nicotine. Nicotine is a highly addictive substance. Vaping product use could result in symptoms of dependence. 
If you are a vaper; vaping vs smoking?
Vaping is less harmful than smoking. Many of the toxic and cancer-causing chemicals in tobacco and the tobacco smoke form when tobacco is burned.    Vaping products do not contain tobacco and do not involve burning or produce smoke. Except for nicotine, vaping products typically only contain a fraction of the 7,000 chemicals found in tobacco or tobacco smoke, and at lower levels.
Switching from tobacco cigarettes to vaping products will reduce a person’s exposure to many toxic and cancer- causing chemicals. As a step towards quitting cigarettes, many smokers may go through a transition period when they use both cigarettes and vaping products. Studies have shown short-term general health improvements in those who have completely switched from smoking cigarettes to vaping products.
Does vaping give you popcorn lung disease?
This is a really popular myth, and through sensationalist media coverage seems to have become ingrained in the minds of many. It has absolutely no foundation in truth, as Martin Dockrell, Tobacco Control Lead at Public Health England explains: “One of the most commonly held safety concerns is that e-cigarettes might cause ‘popcorn lung’. UK vapers have nothing to fear on that count. The concern came about because some flavourings used in e-liquids contain a chemical called diacetyl, and that high level exposure has been associated with ‘popcorn lung’. However, diacetyl is banned from e-cigarettes and e-liquid in the UK. It has been detected in some flavourings in the past, but at hundreds of times Lower levels than observed in cigarettes smoke. Given that even at these levels, smoking is not a major risk factor for this rare disease, the diacetyl content in flavourings would have been unlikely to pose much risk.”
Is it legal?
Yes! Vaping devices are similar to e-cigarettes and are completely legal. There are some legal restrictions on where you can use your vaping device but this will vary by jurisdiction. Many places that ban cigarette smoking indoors have begun to ban e-cigarettes as well. Vaping devices are also banned on planes in some areas.
