Ketamine (low dose)

What this could lead to

If it works, this could point toward a way to reduce opioid cravings and help people stay in treatment longer.

What could go wrong

This is a small, early-phase trial with only 50 participants. The very low dose group acts as a comparison, so the benefit may be small or not last. Ketamine can cause side effects like dizziness or dissociation.
