They should not be lumping ketamine in with all the other psychedelics which act on the serotonin 2A receptor. I’m hesitant to say ketamine is a psychedelic at all. Regardless, I find .25 mg of Klonopin can get rid of my depression as well, they’ve known for a long time that depression has a strong linked glutamate excitation in certain parts of the brain.
Chronic benzo administration can cause depression, so that might not work for everyone. I'd argue that the term "psychedelic dissociative" accurately captures what ketamine can be.
And chronic ketamine use can cause depression as well:

All these drugs are not the answer. It is much more likely there is a fundamental immune dysfunction causing the depression. IMHO, all mood disorder patents should be seen by rheumatologists, not psychiatrists.
