There are a multitude of recent studies looking into the potential adverse side effects of e-cigarettes (which we fully support!) and the jury is still out if vaping is potentially harmful. Saying that though, one thing is clear: using ecigs is a far better option than smoking conventional tobacco cigarettes. 

No one disputes the fact that smoking cigarettes kills, but it still goes on and is a major industry and source of income for governments right through to tobacco growers. It seems like the majority of people may not really realise (or don't want to realise) how lethal smoking really is. The World Health Organization  estimates that tobacco kills up to one half of  its regular users via cardiovacular disease, lung cancer and respiratory illnesses. Currently, in United States of America only, it's estimated that about 30 percent are a result of tobacco use.

This is where the e-cigarette part comes in. They were introduced in the early 2000s, and according to some experts, sales could exceed those of traditional tobacco products within a few years. In the UK only, the number of vapers tripled from 700,000 to 2.1million between 2012 and 2014, according to charity Action on Smoking and Health. A large European survey showed ecigs helped 15 million smokers to quit or cut down and there is little evidence vaping leads to smoking. 

While the vaping industry is booming, the health experts cannot 100 percent agree that vaping is completely harmless. Vapers experience more and more restrictions ( the most recent was obviously the enforcement of the Article 20 of the Tobacco Product Directive in Europe), while some countries, such as New Zealand, ban e-cigarettes that contain nicotine entirely.

Policies that restrict e-smoking are reasonable. We don't know yet what kind of health risks it carries - and yet, we should keep in mind that such vaping is almost certainly safer than conventional smoking: some experts have suggested that e-cigarettes carry only between 3 and 5 percent of the health risks of tobacco smoking. We don't want to ban vaping or make it too hard to do, because if smokers can't quit, they should switch to the less harmful habit.

As with anything, ecigs have their benefits and side effects. E-Cigarette UK pictures them perfectly:

If current assumptions about safety are correct, the risk from e-cigarettes is about on a par with the risk of living with a smoker and inhaling secondhand smoke. That is still significant, and the risk needs to be quantified more precisely: estimates aren't good enough. Unfortunately, that would be prohibitively expensive with current techniques, although emerging testing methods could speed things up over the next several years. In the meantime, however, we cannot ignore the fact that as many as one billion people could be killed by tobacco use during this century. Bringing this number down substantially is an opportunity we cannot miss.
