The club-drug, ketamine, is essentially an animal anaesthetic. Because it gives people pleasure and in large doses can be dangerous, it's illegal for recreational use. But, as we know, the fact that a substance provides pleasure has no correlation with its other potential therapeutic properties. Pharmaceuticals are all pharmaceuticals. So it's encouraging but not surprising that ketamine turns out to have a new and surprising power against clinical depression. More research, please.
