Emergency

Overdose signs

• Natural cannabis rarely causes a medical emergency — "greening out" is: pale/sweaty skin, dizziness, nausea or vomiting, anxiety or panic, rapid heartbeat, feeling faint — and usually passes with rest.
• Seek emergency help for these — far more likely with synthetic cannabinoids ("spice" / K2):
• Seizures
• Severe chest pain; very fast or irregular heartbeat
• Unresponsiveness or extreme drowsiness
• Severe agitation, aggression, or psychosis
• Repeated vomiting; difficulty breathing

First response

• Sit or lie them down somewhere calm, cool, and quiet
• Reassure them — cannabis panic and "greening out" pass with time
• Offer sips of water; a little sugar can help if they feel faint
• Recovery position if nauseated, drowsy, or vomiting
• Stay with them and monitor
• For seizures, chest pain, unresponsiveness, or severe agitation, call emergency services

For the medical team

Tell the dispatcher what was taken — critically, whether it was a synthetic cannabinoid ("spice", "K2", herbal smoking blends) rather than natural cannabis. Synthetics are far more potent and unpredictable, causing seizures, cardiac events, and kidney injury. Note any alcohol or other drugs taken with it.

Resolution

Natural cannabis "greening out" resolves with rest, calm, and time, with no lasting harm. Synthetic cannabinoids are unpredictable and can cause seizures, cardiac events, kidney injury, and severe agitation that needs emergency care.
