An overdose is a biological response to when the human body receives too much of a substance or mix of substances. An overdose can be intentional or accidental. People can overdose on illicit drugs, alcohol, prescription medications, and many other substances. In many cases, overdoses are fatal, although most individuals who have overdosed can be saved if medical treatment is provided quickly enough. Signs of overdose: Recognizing the signs of opioid overdose can save a life. Here are some things to look for:

  • Small, constricted “pinpoint pupils”
  • Falling asleep or losing consciousness
  • Slow, weak, or no breathing
  • Choking or gurgling sounds
  • Limp body
  • Cold and/or clammy skin
  • Discolored skin (especially in lips and nails)

What to do if you suspect an overdose?  It may be hard to tell whether a person is high or experiencing an overdose. If you aren’t sure, treat it like an overdose—you could save a life.

  1. Call 911 Immediately.*
  2. Administer naloxone, if available.**
  3. Try to keep the person awake and breathing.
  4. Lay the person on their side to prevent choking.
  5. Stay with the person until emergency assistance arrives.

*New Mexico’s 911 Good Samaritan Law protects people who seek help for a friend or family member who is experiencing a drug overdose and call 911.**Naloxone, popularly sold by the brand name of Narcan, is an opioid agonist that can block the effects that opioids have on the body. If someone experiences an overdose, depending on the severity, one to several doses of Narcan can actually stop it in progress, and save someone’s life. Narcan is available without prescription across the country. For more information on how to correctly use Narcan, visit

Drug Information

Fentanyl (Opioid):

Fentanyl is a synthetic opioid that is up to 50 times stronger than heroin and 100 times stronger than morphine. There are two types of fentanyl: pharmaceutical fentanyl (PF) and illicitly manufactured fentanyl (IMF). Both are considered synthetic opioids. Pharmaceutical fentanyl is prescribed by doctors to treat severe pain, especially after surgery and for advanced-stage cancer. Over 150 people die every day from overdoses related to synthetic opioids like fentanyl. Most recent cases of fentanyl-related overdose are linked to illicitly manufactured fentanyl, which is distributed through illegal drug markets for its heroin-like effect. It is often added to other drugs because of its extreme potency, which makes drugs cheaper, more powerful, more addictive, and more dangerous. Individuals can intake fentanyl by:

  • Powder, dropped onto blotter paper, put in eye droppers and nasal sprays
  • Made into pills that look like other prescription opioids such as Oxycodone (M30)
  • Pills like M30’s that are crushed and smoked to enhance the effects

Heroin (Opioid):

Heroin is an opioid drug made from morphine, a natural substance taken from the seed pod of the various opium poppy plants grown in Southeast and Southwest Asia, Mexico, and Colombia.

  • Restoring blood flow to the heart (heart attack)
  • Treating the organ problems

  • Restoring blood flow to the heart (heart attack)
  • Restoring oxygen-rich blood supply to the affected part of the brain (stroke)
  • Stopping the seizure

Benzodiazepines (Depressant):

Benzodiazepines are depressants that produce sedation and hypnosis, relieve anxiety and muscle spasms, and reduce seizures.
