The Surgeon General released his latest report on Jan. 14, 50 years after the first report on tobacco in 1964, which linked smoking to lung cancer in men, according to news sources.

The report emphasized half a century of progress in American smoking habits, with smoking rates falling by over half, according to the New York Times.

However, the report found that 13 cancers are now linked to smoking, including liver and colorectal cancer. The report also found that smoking can cause diabetes, erectile dysfunction, macular degeneration, ectopic pregnancies and impaired immune function, CNN reported.

Smoking remains the leading cause of preventable death in the United States, according to the Washington Post.

Of the nearly 42 million Americans addicted to smoking, 70 percent want to quit, the New York Times reported.

The report called for smoke-free laws in all states, better regulation and local anti-tobacco efforts, according to CNN.
