When safety comes first, know where to turn.

Substance-related harm can escalate quickly. This page focuses on recognizing danger, contacting qualified help, preparing a practical emergency plan, and finding support—without providing use or access instructions.

Emergency response and support

Emergency first: If someone may be in immediate danger, call local emergency services now. If you are in the United States, call 911. For poisoning questions, contact Poison Control at poison.org or 1-800-222-1222.

Warning signs that need urgent help

Symptoms vary, and absence of a listed sign does not guarantee safety. Seek urgent medical help when a person has any of the following:

  • Difficulty breathing, blue or gray lips, or repeated choking sounds.
  • Unresponsiveness, inability to stay awake, or sudden collapse.
  • Seizure, severe chest pain, or a very abnormal heartbeat sensation.
  • Severe confusion, extreme agitation, loss of coordination, or sudden weakness.
  • Repeated vomiting, suspected poisoning, or a rapidly worsening condition.
  • A severe allergic reaction, such as swelling of the face or throat with breathing difficulty.

When in doubt, contact emergency services. Tell the dispatcher what you observed, when symptoms began, and what information is available. Do not delay because you are unsure of the substance involved.

What to do while waiting for help

  1. Stay with the person and keep the area as safe and calm as possible.
  2. Follow the dispatcher's instructions. Do not give food, drink, or another substance unless a qualified professional tells you to.
  3. If the person is unconscious but breathing, place them on their side if you can do so safely and follow local first-aid guidance.
  4. Keep containers, packaging, or a written list of known medicines available for responders when this can be done safely.
  5. Do not leave the person alone and do not assume symptoms will pass without assessment.

Build a simple emergency plan

A plan is useful before a crisis. Keep local emergency numbers, the nearest urgent-care or emergency department, a current medicine list, known allergies, and relevant health conditions in an accessible place. Share the plan with someone you trust.

Support is part of safety

People seeking help may need medical care, mental-health support, social support, or all three. Evidence-based care can include assessment by a qualified clinician, counseling, peer support, and treatment for co-occurring conditions. Availability and eligibility vary by location.

In the United States, the Substance Abuse and Mental Health Services Administration provides a national helpline and treatment locator at samhsa.gov. Elsewhere, start with a local health service, primary-care clinician, or national health authority.
