Could Ketamine on the NHS help treat severe depression?

Ketamine, known for its recreational use, is being considered as a treatment for severe depression in Scotland. NHS Lothian is exploring the use of ketamine as an alternative to electroconvulsive therapy for hard-to-treat depression. Private clinics have already started offering ketamine-assisted therapy, but the hope is for wider availability, potentially even through the NHS. Researchers are investigating how ketamine can help with depression, though the exact mechanisms are not fully understood yet.
