A drug can change the way the brain works. This effect will vary depending on the type of drug being taken, the person and the environment.

How to deal with an overdose

When someone overdoses it is important to get them help as soon as possible. Phone 999 right away. Ambulance paramedics have the tools to respond safely. Where personal protective equipment (PPE) isn’t available and you think there may be a risk of infection, the Resuscitation Council UK (RCUK) advises helpers to place a cloth or towel over the victim’s mouth and nose.

Until the ambulance or advanced care team arrives, do compression only CPR and early defibrillation.

Phone 999 or go to A&E if:

Someone else has taken drugs and has symptoms like:

• unconsciousness
• seizures or fitting
• rapid heart beat
• low/undetectable heart rate
• chest pains
• difficulty breathing (snoring or rasping)
• blue/pale tingling of knees, hands and lips
• severe nausea and vomiting
• hyperthermia (overheating)
