Blink 182 rocker Travis Barker said illegal drug use prevented painkillers from working following a fiery plane crash in 2008.
He required multiple life-saving surgeries and skin grafts and was forced to go through much of it without relief.
His body was unable process painkillers properly during the ordeal because of his past illicit drug use.
The Blink-182 star almost burned to death when the plane on which he was flying back to Los Angeles from a gig in South Carolina burst into flames during take-off.
Barker and bandmate Adam 'DJ AM' Goldstein survived, but the drummer's friend and bodyguard perished in the inferno.
