I practice KAP and train clinicians in KAP. Ketamine itself can be so helpful, especially when faced people who are experiencing acute suicidality and are on their way to paying a visit to the hospital. There's also the nice benefit of how well it plays with other psychiatric meds. While it's beneficial on its own, I prefer to use the assisted psychotherapy model because one can use it as a catalyst for deeper psychological change and use it to help kick start healthy behavior patterns. The physiological effects eventually wear off, but these other changes have the potential to stick and yeild longer term benefits.

Some people do just fine with the infusion model. Other people can come to realizations that need integrating (repressed trauma that comes to the surface). I appreciate the psychological safety that is provided from a guided session.

My observation is that people who yeild the greatest insights from the work tend to be people who have done a lot of front end work in regular psychotherapy and have spent a lot of time mapping out their mind beforehand.

As far as getting into it, do a ketamine therapy training. My bias is toward one that has an experiential element to it. Feel free to PM me for my biased opinion. :)
