Cal. Penal Code § 2670

It is hereby recognized and declared that all persons, including all persons involuntarily confined, have a fundamental right against enforced interference with their thought processes, states of mind, and patterns of mentation through the use of organic therapies; that this fundamental right requires that no person with the capacity for informed consent who refuses organic therapy shall be compelled to undergo such therapy; and that in order to justify the use of organic therapy upon a person who lacks the capacity for informed consent, other than psychosurgery as referred to in subdivision (c) of Section 2670.5 which is not to be administered to such persons, the state shall establish that the organic therapy would be beneficial to the person, that there is a compelling interest in administering such therapy, and that there are no less onerous alternatives to such therapy.
