British rocker JOHNNY BORRELL has given up his quest to help Pete Doherty kick his drug addictions, claiming the troubled singer refuses to help himself. Razorlight frontman Borrell credits Doherty with helping him beat his own heroin habit several years ago and he was keen to return the favour. But Borrell says, "I did once say to him that if he fancied having a cup of tea and watching Hancock's Half Hour or something, I'd be up for it, but I wasn't into smoking crack. "I can't help him. I don't think anyone can. You can only help yourself. You can inspire people but you can only help yourself." Doherty was ordered by a judge on Tuesday (03Jul07) to undergo rehab by 7 August or face a jail sentence - after pleading guilty in a London court to drug possession charges.
