GHB/GBL + Alcohol
GHB/GBL + Alcohol: the short answerGHB already has a razor-thin margin between 'high' and 'unconscious,' and alcohol erases it — together they are a leading cause of fatal 'G' overdoses. If someone on this mix cannot be fully woken, call emergency services and put them in the recovery position.
Why it’s dangerous
GHB (and its prodrug GBL) acts on GHB and GABA-B receptors to powerfully suppress the central nervous system, with a very steep dose-response curve — a small amount extra can mean unconsciousness. Alcohol pushes the same GABA system even harder, so the combination deepens sedation, slows breathing, and triggers vomiting in people too sedated to protect their airway. Aspiration of vomit is a common mechanism of death.
What happens
- Sudden loss of consciousness, often mid-conversation ('G-ing out')
- Vomiting while unconscious — high choking risk
- Slow, shallow, or irregular breathing
- Confusion, memory blackouts, and unsteady movements before collapse
Warning signs
- Cannot be woken, or wakes only briefly then drops again
- Vomit around the mouth or choking sounds
- Breathing pauses, snoring/gurgling, blue lips
- Seizure-like twitching or rigidity
What to do
- Call emergency services — G overdoses can stop breathing with little warning
- Place the person in the recovery position immediately and clear any vomit from the mouth
- Stay and monitor breathing continuously until help arrives
- Naloxone does nothing for GHB — do not delay the ambulance call to find it
- Never drink on GHB/GBL; if you use G anyway, never alone, and avoid any other depressant the same night
