(Sacramento, CA) — A new law aimed at making a night on the town less stressful for women in California goes into effect later this year. The law requires bars and nightclubs in the Golden State to offer “roofie” tests to bar patrons to see if their drink has been spiked.

The tests come with a strip or straw that detects common date-rape drugs like ketamine or GHB.

The goal is to protect bar patrons from potential sexual assaults. Bars and nightclubs have until July to start offering the kits. It’s up to each business to decide if they want to charge customers for the kits.
