Mia Tyler's actress mother fed her cannabis seeds when she was just eight years old.The plus-sized model daughter of rocker Steven Tyler and late actress Cyrinda Fox claims the incident kickstarted years of drug abuse.She says of her childhood, "It was challenging. I grew up real fast. I saw things I might not normally see."There were pot seeds around and I would pick them up. My mom thought it was funny if I ate them."But Tyler, 29, whose half-sister is actress Liv Tyler, insists her experiments with drugs and self-harming are behind her now.She adds, "I lead a hard life early on so i can lead an early life now."
