From the article: "In 1946, a new advertising campaign appeared in magazines with a picture of a doctor in a lab coat holding a cigarette and the slogan, “More doctors smoke Camels than any other cigarette.” No, this wasn’t a spoof. Back then, doctors were not aware that smoking could cause cancer, heart disease and lung disease." No, this is a complete fabrication, doctors and researchers were well aware that cigarettes were carcinogenic and caused other lung ailments. Isaac Adler proposed the link in 1912 to lung cancer. The first animal and human studies showing the links started in the 1930s and the connection was well established by the mid-1940s. The reason why the advertisement advertised "More doctors smoke Camels than any other cigarette" is because the general public was becoming aware of the problems with tobacco and the advertisers wanted to use the authority of doctors to create a sense of that their cigarettes were safe without talking about cancer and lung disease.
