RECOVERY POSITION
If someone has overdosed, they could choke on their own vomit. Place them in the recovery position to help save their life.
Kneel next to the person and place the arm closest to you straight out in front of their body. Position the other arm so that the back of the hand is against against the cheek closest to you
Grab and bend the person's far knee. Protect their head with one hand while you gently pull the bent knee towards you until it is touching the ground.
Tilt their head up slightly so that the airway is open. Make sure their hand is under their cheek. Place a blanket over the person (unless they have heat illness or fever) and stay close until help arrives.
