Not graded (4)
Not listed never means safe.
Seek help immediately if
- Severe disorientation; unable to move or speak (deep dissociation / "k-hole")
- Complete loss of coordination — cannot stand or walk safely
- Vomiting while incapacitated (choking / aspiration risk)
- Very high blood pressure; fast heart rate
- Slow or shallow breathing at high doses (especially mixed with depressants)
- Unconsciousness; rarely, seizures
What to do
- Move them somewhere safe, away from stairs, water, roads, and sharp edges — they cannot protect themselves
- Place in the recovery position if vomiting or unconscious (aspiration is a key risk)
- Stay with them and reassure calmly; keep the environment quiet
- If breathing is slow/shallow or they are unresponsive, call emergency services
- Do not let them wander; do not leave them alone
- Be ready to give rescue breaths / CPR
Effects wear off with time in a safe, monitored setting. The main dangers are physical injury and aspiration while incapacitated, and respiratory depression when combined with other depressants — not the dissociation itself.
