What to do
- Say what was taken and how much.Responders need it, and in most US states Good Samaritan laws protect both of you from drug possession charges when you call for an overdose.
- Unresponsive: put them on their side, tilt the head back, and stay until help arrives.Never leave someone alone to “sleep it off”.
- Give naloxone (Narcan) if you have it.It is sold over the counter in every US state and does no harm if opioids turn out not to be involved.
- Never Use Alone 1-800-484-3731Stays on the line and sends help if you stop responding.
- Full steps: what to do if it is already happeningOverdose signs, the recovery position, what to say on the call, and whether you can be charged for making it.

How the ratings workThe longer explanation
7-OH is a strong opioid without kratom's ceiling, and xylazine adds heavy sedation and slowed breathing by a route naloxone cannot reverse.
