I doubt that this restriction applies to any but public employees.
The rest of your post is on point.
California BAN on conversion therapy for anyone UNDER 18.
“The law, adopted last year, was the first of its kind and an unusual effort to regulate a form of talk therapy. It bars licensed therapists from trying to change the sexual orientation of people under the age of 18.”
It applies to all licensed mental health professionals. Any such counseling could result in a loss of the professional license.
SACRAMENTO, Calif. Gov. Jerry Brown has signed legislation that makes California the first state to ban a controversial form of psychotherapy that’s aimed at making gay teenagers straight.
Effective Jan. 1, mental health practitioners are prohibited from performing sexual orientation change efforts known as reparative or conversion therapy for anyone under 18.
The therapies “have no basis in science or medicine and they will now be relegated to the dustbin of quackery,” Brown said in a statement.
Mainstream associations representing psychiatrists and psychologists have dismissed reparative therapy in recent decades. A number of mental health associations in California including the state’s Board of Behavorial Sciences, the California Association of Marriage and Family Therapists and the California Psychological Association supported the legislation.
