Tatum was a precocious child, wasn't she? She won an Oscar at 9 and started smoking pot at 12. "I remained [my father's] companion on the Hollywood party circuit, growing inured to sex and drugs before I was in my teens," she wrote in her autobiography, "A Paper Life." Quaaludes soon followed, as did an opium-fueled orgy with Melanie Griffith. By 18, Tatum was snorting cocaine. The actress has struggled with addiction throughout her adult life.
