What it is

This entry is a classification of session styles, not a single branded therapy. The terms come from mid-20th-century LSD therapy, where "psycholytic" meant repeated lower-intensity sessions used to loosen defences inside an ongoing psychotherapy and "psychedelic" meant a few high-intensity sessions…

Format

• Both styles share one arc: assessment and screening → preparation → ketamine session(s) → post-session recovery → integration → follow-up. They differ mainly in what happens inside the session and in how sessions relate to the wider therapy.
• A later Krupitsky trial compared a single session with repeated sessions, because nearly half the high-intensity group relapsed within three months.

Who practises it, and how they are trained or regulated

• Legal and regulatory status (as of the sources' dates).
• United States: ketamine is FDA-approved only as an anaesthetic and is a controlled substance; psychiatric use of racemic ketamine is off-label. Esketamine (Spravato) is approved for treatment-resistant depression and for depressive symptoms with acute suicidal ideation or behaviour, alongside an antidepressant, under a REMS that restricts dispensing and administration to certified, medically supervised settings with…
• Russia: Krupitsky's research was interrupted by changes to Russian ketamine regulations around 2001 and later rescheduling over recreational-use concerns.

Evidence status, as the guide reports it

• United Kingdom: esketamine holds a marketing authorisation for treatment-resistant depression but NICE did not recommend it for NHS use (uncertain long-term benefit, comparator evidence and cost). Ketamine's UK controlled-drug class is.

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• : insight without behaviour change. Working when: activity and change talk increase between sessions.
• : treating high mystical scores as success in themselves. Working when: data inform the review in 4.16.
• : anchors that fade within days. Working when: the client spontaneously uses the anchor in difficult moments.
• : a client pushing for the "deepest" experience as a goal in itself. Working when: the style follows the therapeutic goals.
• : lingering derealisation; distress on returning home. Working when: the client leaves oriented and has a record of the experience.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
