Ketamine (C13H16CINO), primarily used as an anaesthetic agent during medical operations and considered to be the notorious ‘K-drug’ in rave culture, was in the news in late 2021 as it was found to be effective in reducing depressive symptoms and suicidal thoughts. Known to have dissociative properties, ketamine can relieve pain, induce hallucinations or trance-like states and can be dangerous if used for recreational purposes, which is why it is used under strict legal conditions in India and in other countries. While medical researchers have been studying ketamine therapy since the 1960s and 1970s, it gained traction in the early 2000s as a treatment against depression.
