Cardiovascular surgeon identifies smoking as most dangerous health habit

A heart surgeon has warned that smoking is the most destructive habit a person can have, speaking on a popular American podcast. Dr. Jeremy London, who has performed cardiovascular surgery for more than 25 years, told The Mel Robbins Podcast that tobacco damages every organ in the body. He said smokers face a risk of heart disease that is roughly one hundred times greater than non-smokers, and that smoking directly causes lung cancer.

Dr. London also cautioned against eating too much sugar, having untreated high blood pressure, poor sleep, and drinking alcohol. On nicotine pouches, he said they are probably less dangerous than cigarettes but still carry risks because nicotine narrows blood vessels. He added that good lifestyle choices alone are not enough, and that avoiding necessary medication can be seriously harmful.
