Know the steps to take to prevent an overdose.

1. Don't use alone

  • If you use alone, tell someone before you use, leave the door unlocked and have someone come check on you.
  • When using with someone else, make a plan, don’t use at the same time, be sure your friend is willing to call for help, and check-in on what each of you know about.

2. Know your tolerance

  • Use less drug then before if: you are also taking certain prescription medications (they can impact the body’s ability to process the drugs) and/or you are using after a period of time of non-use (detox, abstinence, hospitalization, jail or new use).

3. Don't mix drugs

  • Do not mix drugs and alcohol. If you do, use the drugs first before the alcohol. Mixing opioids with downers or opioids with uppers puts you at higher risk of overdose; try to take one thing at a time.

4. Know the quality of the drugs

  • The street quality of substances is unpredictable, do testers, go slow, and try to use a consistent reliable dealer.
