5. What is in the vapor that is expelled?

Tests have determined that what is expelled is what is in the cartridges, since no chemical reaction takes place, i.e. as a result of any sort of ignition or burning, there can not be any change in the ingredients of what is expelled. When nicotine cartridges are used, tests have determined that the expelled vapor contains only minimal amounts of nicotine, less than 1%, and that amount dissolves within seconds and represents no health risk to bystanders.
