ROLLING STONE RONNIE WOOD's wife JO regrets sharing a marijuana joint with her daughter when she was 15, but wanted her to understand the lure of drugs. Jo is convinced her tactic worked, as daughter Leah Wood now leads a relatively clean life. She says, "I was smoking pot at the time, and I offered her a spliff. "I know I shouldn't have, but she was at that age where I thought she'd be starting to experiment. I wanted her to have it from me, rather than anyone else. She didn't like it. "I know she doesn't smoke much now. She's aware of the damage that can come with drugs."
