The agony of ketamine addiction: ‘I felt like I was peeing glass’

It is gen Z's recreational drug of choice in the UK and US - and with rising use come big problems, including incontinence, bladder damage, renal failure, depression and extreme pain

The first time Nick (not his real name) tried ketamine, he felt as if he'd entered another dimension. Though he smoked marijuana regularly and had experimented with other drugs, Nick had never even heard of ketamine. But when his friend pulled out a bag of white powder, I did what anybody else would do at 20 years old. I tried it," he says. And I found it really fun, to be honest." The floaty feeling, like he'd been lifted out of his own body, was euphoric", he says. Like you're in a fairy world."

Sixteen years later, reality is biting hard. Nick, now 36, has spent the past three months in recovery for ketamine addiction after more than a decade of heavy use. His bladder is a fifth of the size it should be, he says. It's more than likely" that it will have to be removed and replaced with a urostomy bag.
