California Gov. Gavin Newsom on Friday signed a bill that aims to reduce social media use among children, the latest state effort to regulate the medium over increasing concerns that heavy use is damaging to young people.

California is on the verge of legalizing cannabis cafes, where people can legally smoke weed and eat food inside specialty licensed lounges. Lawmakers have already approved a bill legalizing the cafes and business owners are now waiting to see if Gov. Gavin Newsom will give final approval to the plan.

Senate Bill 976 could inspire legal action by social media companies, which argued the legislation 'unconstitutionally burdens' access to content.
