And more: vision loss, tuberculosis, rheumatoid arthritis, impaired immune function, and, in the children of women who smoke, cleft palates.

The development comes 50 years after a landmark 1964 report first found smoking caused lung cancer; 30 more reports have followed on the topic in advance of the latest.
