Pete Doherty has stopped injecting DRUGS.

The former Libertines rocker - who has had a well documented battle with substance abuse - will not get high from needles any more out of respect for his mystery girlfriend as he doesn't want her to dabble with drugs.

He said of his addictions: "I've stopped injecting.

"The only way I see myself in a serious relationship is if I am toning it down a bit. When you're banging up all day you can't really have someone in your life, especially if she's an English rose. I wouldn't let her touch anything. I just wouldn't."

Pete - who famously dated supermodel Kate Moss from January 2005 and July 2007 - also says he's more calmer in his life since quitting London and moving to the French capital of Paris three years ago.

Speaking to The Independent newspaper, he said: "The media circus got a bit twisted when I was in London. It became a bit of a joke, really. In Paris, they're so serious I can take myself really seriously, too. I can get really morbid without people telling me to cheer up."
