The before showed the boy helmeted, hands tied behind his back, butting his head against a wall. The after showed him calmly sitting at a table, sketching. The difference: two drops of cannabis oil administered below the tongue. The video had been sent to Meiri by Abigail Dar, an Israeli champion for the use of cannabis in children with autism.
