Universal Harm Reduction Principles

  • Start low, go slow. Assess potency with a small test dose before full use.
  • Never use alone. Inform someone of your location and what you are taking.
  • Test your substances. Fentanyl and other adulterants appear across many drug categories.
  • Know your interactions. Check combinations at TripSit Combo Chart.
  • Have naloxone available. Anyone near opioid use should carry naloxone and know how to use it.
Emergency: If someone is unresponsive and not breathing normally, call emergency services immediately. See the overdose response guide.
