Combining ketamine with psychotherapy may be more effective than either treatment alone for chronic pain and mental health conditions. A pilot study from St. Michael's Hospital found that ~80% of patients receiving both treatments saw meaningful reductions in pain interference scores. Experts say the combo takes advantage of ketamine's neuroplasticity window to make psychological gains stick.
Ketamine has long been a workhorse drug — from battlefield anesthesia to emergency sedation — but a growing body of research suggests its real potential may lie in combination with psychotherapy. A new pilot study from St. Michael's Hospital in Toronto, published in Med, found that pairing ketamine infusions with weekly psychotherapy sessions was both feasible and safe for patients with chronic neuropathic pain, with the combo outperforming either treatment alone.
The science behind the synergy: ketamine triggers a state of neuroplasticity — essentially opening a window where the brain is more receptive to change. Researchers and clinicians argue that psychotherapy during this window can help patients translate ketamine's short-lived mood and pain relief into lasting behavioral shifts. This idea underpins the "Montreal Model," developed at McGill University's Jewish General Hospital, which pairs ketamine with structured psychiatric care and maintenance sessions.
By the Numbers:
Why it matters: Chronic pain and mental health conditions frequently co-occur and are notoriously hard to treat. Ketamine-assisted therapy offers a promising, versatile approach — but cost and accessibility remain barriers, as the drug isn't routinely covered by provincial health plans in Canada.
