Cal. Educ. Code § 49005.2

A pupil has the right to be free from the use of seclusion and behavioral restraints of any form imposed as a means of coercion, discipline, convenience, or retaliation by staff. This right includes, but is not limited to, the right to be free from the use of a drug administered to the pupil in order to control the pupil’s behavior or to restrict the pupil’s freedom of movement, if that drug is not a standard treatment for the pupil’s medical or psychiatric condition.
