Chemicals can be inadvertently produced, particularly carbonyls similar to formaldehyde, acetaldehyde, acrolein, and E LIQUIDS glyoxal when the nichrome wire (heating component) reaches a high sufficient temperature.

Another 2015 study reported that "dripping", the place the E LIQUIDS-liquid is dripped instantly onto the atomizer, can create carbonyls. Propylene glycol-containing liquids produced the most amounts of carbonyls.
