Did you know that you could increase the percentage to which your electronic cigarette is safer than smoking tobacco cigarettes? Researchers went out to find out the proportion of potential carcinogens and other hazardous substances in electronic cigarette liquids. The findings revealed that the flavorings in those liquids created a bigger number of hazardous substances, such as formaldehyde, when the e-liquid was heated and vaporized. The concentration of the hazardous substances depended on the quantity of flavorings in the liquids. The liquids without flavorings had low levels of those toxic substances during the study. It would therefore be a smart move for you to reduce your consumption of flavored e-cig liquids so that you can lower your exposure to those potentially harmful substances.
