Since its invention, the e-cigarette has been used by teenagers and adults worldwide. During the last decade, the number of vapers has constantly increased. Many people used it as a substitute for cigarettes, but many others utilized it just because they like the flavour. That’s the case of teenagers. In many parts of the world, the e-cigarette market is not regulated and many young people started to vape. But what are the consequences for health? Recent studies have found that vaping can damage the brain, heart, lungs and blood vessel. Some places around the world have already banned the production and sales of e-cigarettes. In total, 28 countries have totally prohibited vape.
