Ketamine has become the generation-defining drug for young Brits. A report from November 2020 stated one in 30 young people admitted to taking the drug in the past year – the highest number since records began and far more than other countries in Europe. The latest figures also suggest that ketamine is now the fourth drug of choice for young people behind cannabis, ecstasy and cocaine. There is a certain cognitive dissonance at the heart of Generation K: On the one hand, we see it as a silly, wonky horse tranquilliser. On the other hand, it is literally a horse tranquilliser... A horse tranquilliser that can make you piss blood. As it has grown in popularity, so have bladder injuries and addictions. In this report, Matt Shea gets deep into the UK’s Generation K, and finds out how a party drug can go too far.
