For instance, it has nicotine, flavoring, propylene glycol and vegetable glycerin. All these differ in ratios but the ingredients list is usually the same in all. When these substances are heated, they function just like any other liquid and evaporate to form vapor. These are inhaled by users. The harmful effects aren’t the same because unlike cigarettes, the vape e-juice doesn’t burn and doesn’t have the toxins which act as carcinogens.
