First steps
- Stop eating or drinking anything with THC.
- Move to a quiet, safe room. Dim the lights. Sit or lie down.
- Drink water in small sips. Eat a light snack if you feel shaky.
- Tell a trusted person how you feel. Ask them to stay with you.
- Set a timer for 30 minutes. Check whether symptoms are getting better, worse, or staying the same.
What helps while you wait
- Rest. Sleep if you can.
- Breathe slowly. Inhale for 4 seconds, hold for 4, exhale for 6.
- Keep the room cool and quiet.
- Use grounding: name 5 things you see, 4 you feel, 3 you hear.
