Studies have shown that second hand smoke affects more people than the direct use of tobacco. Therefore, experts are suggesting that family doctors counsel more patients on the risks of exposure to second hand smoke.

Currently, it is estimated that family doctors only counsel approximately one-third of all parents who visit on the harms second hand smoke can cause on their children. Children and people with respiratory problems are especially at risk from second hand smoke.

A study conducted by three U.S. health experts suggests doctors should discuss the dangers of both using tobacco directly and second hand smoke. It is hoped that more patients would choose to have a smoke-free home to lower their health risks.
