Smoking and drinking both cause cancer, yet only tobacco products come with health warning labels. Experts say It’s time for a change. Last week, U.S. Surgeon General Vivek Murthy said that alcoholic drinks should carry a warning about cancer risks on their label.

Surgeon General Vivek Murthy, MD, recently released an advisory that calls for adding cancer warning labels to alcohol. The report said that alcohol consumption is the third leading preventable cause of cancer in the United States, after tobacco and obesity.

Even advocacy groups supportive of more warnings about alcohol acknowledged the effort faces serious challenges.
