It is because of these varying nicotine strengths in electronic cigarettes that you can choose between using electronic cigarettes more as a smoking alternative than a smoking cessation device.
Electronic cigarettes give you the same physical sensation that smokers are used to from real cigarettes. In addition to this, it also helps in satisfy tobacco cravings as your lungs get filled with tobacco flavoured smoke when inhaling.
On exhaling, the smoke comes out just like it would do while smoking a regular cigarette but quickly disperses to ensure it does not harm anyone or the environment. With electronic cigarettes, you also keep the environment much cleaner as there are no cigarette butts to throw or drop anywhere.
It could be said that the electronic cigarette is a tobacco replacement device as it does not have any tobacco in it and in addition to all these healthier benefits when compared to a normal cigarette, an electronic cigarette is much cheaper than a traditional cigarette.
