GHB/GBL, alcohol and benzodiazepines all act as depressants on the central nervous system — specifically on the respiratory center. In combination these effects potentiate each other (synergy rather than addition).
There is no antidote that cleanly reverses this mix:
- Naloxone has no effect (no opioids involved)
- Flumazenil can reverse the benzo effect, but in chronic benzo use it can trigger seizures — a task for the emergency physicians, not for laypeople
- GHB has no antidote either
The only lay intervention in an emergency:
- Call 112
- Secure the airway (recovery position)
- Resuscitation if breathing stops
Rendering assistance is a legal duty under § 323c StGB (German Criminal Code). levelll cannot rule out prosecution, but anyone who gets help is acting lawfully.
