Although not well-established at this time, there is evidence to suggest that e cigarettes may be introducing cancer-causing chemicals to the lungs. The high temperatures used by e cigarettes to produce vapor can also transform some chemicals in the vapor-producing liquid into more harmful substances. This can produce compounds known as carbonyls, which include cancer causing chemicals such as formaldehyde, and another suspected carcinogen called acetaldehyde.
