The primary danger to pets is the nicotine they can be exposed to. There is a cartridge in the e-cigarette that contains nicotine at levels toxic to animals. Pets may be exposed when they chew up the e-cigs or the bottles containing e-juice, or even when they walk through puddles of spilled e-juice and get it on their paws. The signs of nicotine poisoning may begin within 15 to 30 minutes of exposure to the e-liquid; in contrast, signs of nicotine poisoning following eating tobacco products may take a few hours as the nicotine must be released from the tobacco.
