A range of signs and symptoms can occur when a person overdoses, and everyone responds differently. Signs and symptoms depend on a variety of factors including which drug is taken, the amount taken and the person’s state of health at the time.
If you can’t get a response from someone, do not assume they are asleep. Sometimes it can take hours for someone who has overdosed to die.
An overdose is a medical emergency that requires immediate medical attention. Always call an ambulance if you suspect someone has overdosed.
