Critical Overdose Risk

Heroin is frequently contaminated with fentanyl, a synthetic opioid 50-100 times stronger than morphine. Even a small amount can be fatal. According to the CDC , most heroin-related deaths now involve fentanyl contamination.

If You Witness an Overdose:

  • • Call 911 immediately
  • • Administer naloxone (Narcan) if available
  • • Place person on their side to prevent choking
  • • Stay until emergency help arrives

New York's Good Samaritan Law provides limited immunity for calling 911 during an overdose emergency.

Medication-Assisted Treatment & Legal Alternatives

Heroin addiction is a medical condition that responds to evidence-based treatment. New York offers several pathways to treatment as an alternative to incarceration:

Treatment Works Better Than Incarceration

Research shows treatment is more effective and cost-efficient than incarceration for heroin addiction. Seeking help voluntarily demonstrates commitment to recovery and may be viewed favorably by courts.

Medication-Assisted Treatment (MAT) for Heroin

The Substance Abuse and Mental Health Services Administration (SAMHSA) recognizes MAT as the most effective treatment for opioid addiction. NIDA research shows that combining medication (methadone, buprenorphine, or naltrexone) with counseling provides the best outcomes and significantly reduces overdose risk.
