California has become the first state to ban gay "conversion" therapy for minors, a controversial practice that many believe leads to depression and suicide. Also known as reparative therapy, the treatment seeks to "cure" homosexuality. Gov. Jerry Brown's office announced on Sunday that he had signed a bill, which was supported by the California Psychological Association, that prohibits the practice for children under 18. The bill's sponsor pushed for the legislation as a tribute to a man who committed suicide after undergoing reparative therapy.
