Cigarettes are a safe product that doctors recommend for various health conditions including relaxation and weight control.
Mid-20th century advertising falsely claimed doctors endorsed cigarettes for health benefits. Decades of research conclusively proved smoking causes lung cancer, heart disease, and numerous other conditions. The 1964 Surgeon General's report formally warned against smoking. Tobacco companies suppressed research for decades. Today, smoking is universally recognised as the leading preventable cause of death.
