AceShowbiz - Ronnie Wood's stepson Jamie began collecting pre-rolled joints from The Rolling Stones star's parties when he was "nine or 10," he revealed in a new interview.

The 45-year-old, who grew up with the guitarist and his mum Jo Wood, told Britain's Daily Mail newspaper he was "damaged" by his "drug-fuelled childhood" in which drugs were normalised for him.

"Mum and Dad (by which he means Ronnie) used to party a lot and you could always smell cannabis in the house," he told the publication. "It would waft up the stairs and when I was nine or 10, I'd run downstairs and find ashtrays full of joints and help myself, then stash them behind the microphones."

"It was part and parcel of my upbringing. Drugs were normal in my family but outside they were demonised - no one would let their children come to my house after school."

Jamie, whose biological father is Peter Greene, claimed his unconventional upbringing led to his heroin and cocaine addiction, revealing, "I definitely had a few accidental slight overdoses as a kid."

"I certainly damaged myself. What do you expect? I grew up in that environment. I thought it was natural for me to take drugs," he explained. "Mum and Dad always knew about the drugs but were pretty aware that I was going to make my own decisions."

Jamie, who is now a dad to sons Charlie, 20, Leo, 14, Kobi, 11, and Bo, four, and despite previously patching up their relationship, remains estranged from Ronnie, following another fall-out when the 73-year-old turned his life around and became a dad again to twins Alice and Gracie.
