What to do in a crisis If someone overdoses or has an bad reaction while using ecstasy, it is very important that they receive professional help as soon as possible. A quick response can save their life. Call an ambulance. Dial 000. Don't delay because you think you or your friend might get into trouble. Ambulance officers are not obliged to involve the police. Stay with the person until the ambulance arrives. Ensure the person has adequate air, by keeping crowds back and opening windows. Loosen tight clothing. If the person is unconscious, don’t leave them on their back - they could choke. Turn them on their side and into the recovery position. Gently tilt their head back so their tongue does not block the airway. If breathing has stopped, give mouth-to-mouth resuscitation. If there is no pulse, apply CPR. Provide the ambulance officers with as much information as you can - what drugs were taken, how long ago, and any pre-existing medical conditions. Before using ecstasy, make sure you and your friends know what to do in a crisis.
