Pete Doherty once took so many drugs he thought he was an air hostess.
The Babyshambles rocker began hallucinating after injecting horse tranquiliser ketamine while he was working on the band's 2007 album 'Shotter's Nation'.
Pete said: "Snorting it is bad enough but injecting it is the equivalent of... well, there is no explanation. One minute you're a perfectly sane human being working on what should be an album you're proud of and committed to - the next you're an air hostess on an airplane bound for Portugal."
Pete, 30, was dating British supermodel Kate Moss at the time, and claims the incident was one of the reasons for their split.
He explained to Britain's Elle magazine: "Imagine, there's millions of you inside a little tube which is going up a dog's ear. And your producer Stephen Street is carrying you from the toilets. And then your girlfriend turns up and starts shouting at Stephen Street, 'What's all this? What are you doing?' Stephen's like, 'Oh f***ing hell, we've got a vocal to do.' And I'm like, 'Do you want another drink?' Because I thought I was an air hostess."
