Onetime party drug hailed as miracle for treating severe depression

The Washington Post:

The clinical trial would be his last attempt at salvation. For 40 minutes, he sat in a hospital room as an IV drip delivered ketamine through his system. Several more hours passed before it occurred to him that all his thoughts of suicide had evaporated.
