Adorable Drew may have won our hearts in E.T., but life as a child star wasn't easy for the gal. Drew struggled with a slew of addictions all at a young age: from cigarettes at age 9, to booze by 11, to marijuana at 12, and cocaine by age 13. Following a suicide attempt at 14, she successfully emancipated herself and stayed committed to sobriety. As for papa Barrymore? He dabbled in and out of jail during the 1960s for drug use, public drunkenness and spousal abuse. And to take it back one generation further? Granddaddy Barrymore suffered from major health problems due to alcohol.
