According to a study, the three specific reasons for vaping are: to help quit smoking, prevent smoking recurrence and reduce the number of smokers. Just as sugar substitutes can help people reduce their sugar intake, vape can help people reduce direct smoking or even quit smoking. However, it seems that governments in many countries and regions have not widely promoted vape to replace cigarettes. This phenomenon is caused by many reasons.

But it is undeniable that when a smoker chooses vape, he or she may quit smoking. Some vapers who care about their health believe that nicotine-free vape e-liquid is a better choice than smoking.

What needs to be clear are that vape have not yet been recognized by all smokers. Among these smokers, nearly half of them have tried vape but no longer use e-cigarettes. The reason is that about a quarter of them said: "I don't think they are smoking." In addition, a few people think that vaping do not have the feeling of direct smoking.

All in all, although vaping seem to be smoking, it is not as harmful as smoking. Therefore, when 8 million people worldwide die from smoking-related causes every year, the emergence of vape is very meaningful to help quit smoking.
