Ketamine to treat depression - calling it 'horse tranquilizer' doesn't help

What do you know about ketamine? That it's a party drug, and an anaesthetic for horses? Both are true, but this is not helping it get taken seriously for other potential uses. Ketamine has huge potential as a treatment for depression, according to Dr Tiago Marques, a psychiatrist and senior clinical fellow at Imperial College London.

He talks about rising mental health problems over the lockdowns, how ketamine and other drugs could help, and the important steps to take before starting any treatment for depression. 

Tiago is also CEO of Pasithea Therapeutics, a biotech company focused on mental health.
