![]() ![]() Studies have also shown no improvement in lung function or inflammation in the lungs in smokers who switched to heated tobacco. Studies in both animals and humans have suggested the products cause harm to the lungs. There is some evidence that new chemicals exist in heat-not-burn products that are not present in traditional cigarettes, and which could be toxic and harmful. In fact, more than 20 harmful chemicals were found in heatnot-burn products in higher amounts than in traditional cigarette smoke exposure to harmful chemicals is also higher compared to e-cigarettes. There is currently no evidence showing that these products are less harmful than traditional cigarettes. They contain nicotine, additives and are often flavoured. The tobacco is heated to a high temperature, without setting it alight and creating ‘smoke’ that the user sucks in. ‘Heat not burn’ or ‘smokeless tobacco’ products are electronic devices that, unlike e-cigarettes, contain tobacco. Between 20 in the USA, use of e-cigarettes rose from 1.5% to 20.8%. ![]() Recent surveys in the USA and some European countries have shown increases in e-cigarette use in young people. There is evidence that the use of e-cigarettes has led to children and young adults taking up smoking, as e-cigarette users are more likely to try tobacco products. Overall, there is not enough evidence to show whether e-cigarettes can be used as a successful tool to help smokers quit. There is growing evidence that using e-cigarettes and conventional cigarettes is more harmful than smoking alone. But most of them end up using both e-cigarettes and tobacco. Research suggests that most adults buy e-cigarettes to quit smoking. There are some studies that have shown that e-cigarettes can be used as a quitting aid, but there is a lack of evidence over whether these work as well as established methods. No e-cigarette brand has been approved as an aid to quit smoking. The levels of nicotine vary considerably and are not regulated by health agencies. E-cigarettes can be purchased in shops on the high street and users will not usually access any wider therapies to help them to quit. The medical quitting methods are also regulated as health products with controlled levels of nicotine and the user may also be referred to psychological services for support fighting their addiction. Traditional quitting methods, such as nicotine patches and gum, are usually offered by a pharmacy where a pharmacist can provide advice. Over 40 countries have banned the sale of e-cigarettes. A few countries are considering whether to offer e-cigarettes as part of a treatment plan to quit smoking, in a similar way to traditional quitting methods. Usually e-cigarettes are purchased as a consumer product. The cause of this illness is not yet understood, but research is ongoing to learn more about it.Īlmost all independent research has revealed some negative health effects of e-cigarettes, and existing evidence indicates that this damage will have lasting effects and lead to the development of diseases.Į-cigarettes are often used by smokers who are trying to quit. In some cases, these patients became very ill and were hospitalised and in the most extreme cases, a small number of patients died. Doctors in the USA reported cases of people with symptoms including shortness of breath, fever, cough, vomiting, diarrhoea, headache, dizziness and chest pain. Large surveys have revealed that e-cigarette users more frequently report lung symptoms than people who have never used them.Īn illness known as vaping-related lung injury began to be seen in 2019. Studies have shown that healthy e-cigarette users have irritation in the airways and signs of bronchitis. Inflammation in the lungs can cause difficulty breathing, shortness of breath and a dry cough. There is evidence that cells in the body that are exposed to vapour become damaged and stop working, and evidence showing a link between the vapour and chance of inflammation and infections in the lungs. These chemicals were mostly, but not always, found in lower amounts in e-cigarettes compared to normal cigarettes. These studies have found toxic and cancer-causing chemicals in the vapour of e-cigarettes. There are many studies that have looked into the short-term impact of e-cigarettes on health. This means that their long-term safety is not yet known. Diseases caused by smoking can take 30-50 years to develop and e-cigarettes have only been in widespread use since the early 2000s. As the products are relatively new, there are no long-term studies yet looking at the impact of e-cigarettes across someone’s lifetime. Also e-cigarettes are constantly changing with new devices emerging there are currently hundreds of brands and thousands of flavours available. Research into the safety of e-cigarettes is complicated as there are differences between devices and the way people use the devices. ![]()
