The majority of studies conducted all over the world have demonstrated that vaping an electronic cigarette is less harmful than smoking the traditional cigarettes. The main ingredients found in the oils used in e-cigarettes are propylene glycol, glycerine, and nicotine, as opposed to the thousands of toxic substances identified in cigarettes, which are produced through burning. According to a journal article titled Public Health Consequences of the E-cigarettes, some liquids can contain nitrosamines, and ethylene glycol, known as carcinogenic substances “in addition to PG and glycerol, studies have also identified ethylene glycol as a solvent used in e-liquids. … Most e-cigarette liquids do not contain ethylene glycol and, where present, it is at levels that are not likely to contribute significantly to adverse health effects”.

Although the toxic substances in e-cigarettes are seldomly found, we can’t assume that these substances are completely not carcinogenic. The threshold of carcinogenesis of these substances is unknown and they are not the only factors that contribute or cause pulmonary diseases including cancer. The only thing science can agree on so far is that these substances are less harmful than those found in traditional cigarettes. The benefits of vaping are assumed as a result of witnessing the power it has in aiding adult smokers to give up the habit, and it is the leading preferred method of quitting, taking over pharmaceutical alternatives.

Vaping remains a great option for adult smokers, who struggle or can’t quit smoking, and is highly promoted in many anti-smoking campaigns that concentrate on giving people access to the best alternatives. Science and the medical community remainsceptical on certain issues, but assure smokers that vaping is significantly less harmful than smoking. To avoid vaping unknown substances they advise staying away from illegal and counterfeit products. Vaping is not intended to be seen as a preventive measure of smoking and should not be encouraged within the vulnerable groups of teenagers and young adults.
