After watching my daughter on ketamine when she was given it so they could manipulate the compound fratures into place before surgery.... I can see why this is done in a clinical setting and not at home. She stayed conscious but she was hallucinating very badly. I am sure it would have been a higher dose than they would use for depression. And she is a child so a bigger reaction likely. She was also kept on oxygen. But I understand why this is not given at home.

Ketamine does have a long standing recreational use and street value.

Also my daughter has no memory of that, she was screaming in tho during the manipulatiin so she did feel it, which seems similar to drug Versed which is also used for medical procedures for its amnesia qualities.
