We all know that smoking tobacco has a detrimental effect on our health, and this is something that entered public consciousness back in the 1950s. Smoking has links with deadly diseases such as pneumonia, emphysema and, above all else, cancer. However, in spite of the fact that we have it drilled into us from a very young age that smoking can kill you, over a billion people across the world continue to engage in this very lethal habit. That's a seventh of the population who are seemingly willing to risk an earlier death simply so they can inhale smoke into their lungs. The good thing is, many of these smokers at some point in their lives will try to give up this dangerous habit. Some do it by quitting cold turkey, some use nicotine patches and some continue to smoke using an alternative to tobacco cigarettes. In fact, e-cigarettes were invented purely as a means to help people quit smoking. Vaping from e-cigarettes is seen as a better, less harmful alternative to smoking tobacco cigarettes. And that's because studies had shown that smoke from e-cigarettes is able to deliver the nicotine through aerosols without actually burning tobacco. Plus, e-cigarettes also contain organic solvents which are not hugely harmful when inhaled through the smoke. Tobacco smoke, on the other hand, contains numerous carcinogenic chemicals that arise from the tobacco being burned.
