Dr. Campbell first explained how e-cigarettes differ from traditional cigarettes. He said e-cigarettes don't contain tobacco, but do possess the addictive nicotine. It's not certain what other substances are in the vapor produced by an e-cigarette.
As to their safety, Dr. Campbell said, although most medical communities have come out strongly against e-cigarettes, it's not clear. He said we know cigarettes are dangerous and the leading cause of death in the U.S., but added e-cigarettes may offer an effective way to help smokers quit, especially those who have failed other approaches.
Dr. Campbell noted children should be prohibited from using them, and non-smokers should not try them. He said more research overall on e-cigarettes is needed.
