What is an overdose?
An opioid overdose is a medical emergency that occurs when a person takes an amount of a drug or combination of drugs that is more than their body can process. Because opioids cause respiratory depression, taking more than the body can handle can cause breathing to slow, become irregular, or stop. As a consequence, the person can lose consciousness and eventually die.
Anyone can overdose – experiences users, new users, young or old.
