Alcohol becomes life-threatening at blood alcohol levels from around 3 ‰ — but this varies greatly between individuals. Mixed use with other depressant substances (benzos, GHB, opioids) or with cocaine/cocaethylene lowers the threshold considerably.
Symptoms in the critical range:
- Unconsciousness, cannot be woken
- Irregular or shallow breathing (< 10/min)
- Cold, clammy skin, blue lips
- Vomiting without a swallowing reflex
- Seizures (see separate scenario)
The body breaks down alcohol at about 0.1–0.15 ‰/h — this cannot be sped up. Letting them sleep it off is only okay with stable breathing in the recovery position and with someone present.
When mixed with cocaine, cocaethylene forms, a metabolite with a longer duration of action and higher cardiac toxicity than cocaine alone (see Cocaine-Alcohol Mix).
