Given that you can't force a drug test, and your friend is currently potentially high, here's what you can do in the immediate moment to prioritize their safety and well-being:
1. Stay Calm and Reassuring:
Your calm demeanor is crucial. If you panic, they might also panic, which can worsen a negative high.
Reassure them: Tell them they're safe, you're there for them, and the feeling will pass. If they're experiencing paranoia or anxiety, this is especially important.
2. Create a Safe and Calm Environment:
Move to a quiet space: If you're in a noisy or overwhelming place, try to get them to a quiet, familiar, and comfortable spot. Dim the lights if possible, turn off loud music.
Remove any potential dangers: Discreetly move sharp objects, breakables, or anything they could trip over if their coordination is impaired.
