(CNN)State laws that restrict access to guns could reduce the rate of firearm-related suicide, according to new research.
Researchers examined suicide rates in Connecticut and Missouri, two states that changed their permit-to-purchase handgun laws in recent decades. Connecticut passed a law in 1995 that requires people to apply for a permit with local law enforcement and take eight hours of gun safety training before they can buy a firearm. In 2007 in Missouri, the state repealed a 1921 law that required people to apply with the local police to buy a gun.
