Consumers of the mod are not at risk of inhaling nicotine as the only harmful substance. It is necessary to note that mod consumers customize it to the designs and capacities they want. Most of the users of mod overheat the e-liquid. Since the consumer regulates the heating, thermal decomposition causes the dismantling of basic ingredients resulting in toxic metal substances like chromium, nickel, and lead into the e-liquid. Some of these metals such as formaldehyde are cancer-causing agents. Though overheated e-liquid tastes bitter, consumers seldom detect the difference.
