My quick web search says California outlawed conversion therapy in 2012. Since then there has been attempts to side step it since the language restricts "mental health providers", which is a licensed group. But others can still try to convert people, such as at a camp. Now they can't say they are providing treatment legally, so it seems like California can and did outlaw it, but they are playing whack-a-mole, with people trying to get around the law on language technicalities. CA should definitely plug those holes, but really no one should be believing what these not licensed quacks are trying to sell either.

Me be executive order vs legislation speed issue
