Recently introduced laws by government, including restrictions imposed on smoking in public areas, have been claimed to have helped save lives of many.

Two different studies concluded that these laws implemented to decline smoking rates have helped bring about a significant drop in the number of hospital admissions and also declined mortality rates, which arise due to smoking.

In 2009, Institute of Medicine suggested that the bans were able to bring about a decrease in the number heart problems; however, it was not able to estimate the extent of benefit from the implementation of the laws.

A recent study has provided enough evidences to demonstrate the impact of the laws on health. It suggests that the after smoke-free laws were effective across US and other countries; there was a lowering in the rate of heart attacks.

A study published in Archives of Internal Medicine saw researchers at Minnesota's Mayo Clinic assessing the impact of the laws on health of over 144,000 residents in Olmstead County.

It was concluded that heart attacks declined by 33% after restricting smoking in restaurants and workplaces and other public areas.

Since 2000, majority of states in the US endorsed laws to even put a ban on indoor smoking. Rather, backing the smoke-free laws, even countries like Germany, Bhutan, and Vietnam have implemented them.
