Electronic cigarettes have been classified as a nicotine delivery device. Technically speaking, this term is not totally correct when one takes into account the fact that the e-liquids, the content of ecigs that turn into vapor, which contain no nicotine.

Still, not all e-smokers use the non-nicotine strength level. There are various nicotine strengths which range from extra strong which is 24 mg to low of 6 mg, and there is the no nicotine strength.

What makes a person get addicted to tobacco products is nicotine.

There are some people who use ecigarettes to stop smoking by gradually decreasing their nicotine strength intake to not suffer from the withdrawal symptoms. There are some ex-smokers who didn't need to do so and have quit smoking by going cold turkey.

If one uses electronic cigarettes to stop smoking and intakes a high level of nicotine, is it safe?

According to Maciej Goniewicz, an oncologist from Roswell Park Cancer Institute located in Buffalo, New York, in a news report by the BBC, after analyzing electronic cigarettes and the vapor created, "Nicotine is not very dangerous, and it's very unlikely someone will overdose on the nicotine in electronic cigarettes by inhaling the vapour."

Electronic cigarettes have entered the market a decade ago. Since then, a lot of concerns about how safe it is has been brought up and it's good to know that one of the ingredients of ecigarettes, which is nicotine, cannot be overdosed.

As of the moment, there are insufficient research studies for the other ingredients in electronic cigarettes that would make them be categorized as safe though most brand manufacturers use FDA approved ingredients in their formulation.

There are countries that have banned the use and selling of ecigarettes but in New Zealand, these are regulated and sold in pharmacies.
