MISSOURI (AP) — The Associated Press reports that many new laws are set to take effect today.

Most adults will be able to carry concealed weapons without needing a permit. This law would also expand the state’s “castle doctrine”, which permits homeowners to use deadly force against intruders. The revised law allows invited guests, such as babysitters, to use lethal force. It will also create a “stand-your-ground” right, meaning people no longer would need to retreat from danger before shooting in any place they are legally entitled to be present.

National Rifle Association spokeswoman Nicole Waugh said in an email that the new laws will make Missouri safer and allow law-abiding gun owners to carry firearms and protect themselves. Opponents argue the opposite.

“Now there will be people among us when we’re out with our kids who are carrying concealed firearms without any training at all. Some of them could be dangerous people,” said Becky Morgan, leader of Moms Demand Action for Gun Sense in America. “That’s just our new reality.”

A revision of the criminal code reduces possible prison sentences for some nonviolent drug crimes, and jail time will no longer be a possibility for first time offenders possessing less than 10 grams of marijuana.

The Department of Social Services will contract with a private company to check welfare recipients’ eligibility for benefits, including food stamps, child care, Medicaid and cash welfare payments. Questionable cases will be flagged for further review.
