The Experience
What does ketamine therapy actually feel like?
Honest, research-backed answers about the ketamine experience — what patients report, how clinical doses differ from recreational use, and why the dissociative effects matter for healing.
The honest answer
What you actually feel during an infusion
The word 'high' carries a lot of baggage. Here's what patients actually report — in their own words, from session notes and post-treatment surveys.
'Calm and present'
Most common description. Relaxed but aware of your surroundings. Background sounds fade but you're not unconscious.
'Floating or weightless'
The dissociative effect — detached from physical sensations. A welcome break from constant mental noise.
'Dreamlike but in control'
Similar to the space between sleep and waking. You can open your eyes, speak, and respond to your provider.
'Mild visual effects'
Mild color saturation or softening of edges — like a watercolor painting. Most don't experience this at lower doses.
How they differ
Clinical doses vs. recreational use
| Factor | Clinical (IV infusion) | Recreational |
|---|---|---|
| Dose | 0.5 mg/kg over 40-60 minutes | 50-200+ mg, rapidly |
| Route | IV, precisely controlled | Nasal, of unknown purity |
| Setting | Medical, supervised, monitored | Uncontrolled, often chaotic |
| Goal | Neural healing, symptom relief | Altered state for its own sake |
The therapeutic role
Why the dissociation matters
Default Mode Network reset
Ketamine temporarily reduces activity in the Default Mode Network — the brain's 'background noise' circuit for rumination.
Glutamate surge
Ketamine triggers a glutamate surge, driving the growth of new neural connections.
Reduced negative self-talk
During the dissociative window, the constant loop of negative self-talk quiets. A profound break for people with treatment-resistant depression.
Common questions
Frequently asked questions
Does ketamine therapy feel like being high?
At clinical doses, the experience is often described as calm, floating, or dreamlike. Most patients do not feel 'high' in the recreational sense.
Will I hallucinate during my infusion?
At the 0.5 mg/kg dose used for depression, true hallucinations are uncommon. Some patients report mild visual effects or a dreamlike quality.
Is ketamine therapy addictive?
Ketamine has abuse potential with unregulated recreational use. At clinical doses given under medical supervision, the risk of dependence is very low.
What if I don't like the dissociative feeling?
We can adjust the dose or shorten the duration. Some patients prefer a lower dose that produces minimal dissociation with the same antidepressant benefit.
Can I drive myself home after a session?
No. Your coordination and judgment will be impaired for several hours. You must have someone drive you home.
How does ketamine compare to 'party drug' ketamine?
Therapeutic ketamine is given at a fraction of recreational doses, via IV under medical supervision. The goal is neural healing — not intoxication.
