A Hollywood physician’s medical license was revoked after he recommended that a father give his 4-year-old son marijuana cookies to help with his temper tantrums, according to California’s medical board. Dr. William Eidelman, a natural medicine physician, improperly diagnosed the boy with attention deficit hyperactivity disorder (ADHD) and bipolar disorder before recommending marijuana as a treatment, the medical board said in a decision announced last month. The board clarified that it didn’t find fault with recommending marijuana to a child, but with Eidelman’s diagnosis without sufficient basis. The board found Eidelman was “grossly negligent” for not consulting a psychiatrist and not collecting adequate information from the boy’s teachers and parents. Eidelman’s license was revoked as of Jan. 4.
