Oscar-winning actress Halle Berry regrets smoking marijuana as a teenager, because it made her so paranoid that she couldn't face the outside world. The MONSTER'S BALL star insists she has never tried anything stronger than marijuana, and blasts celebrities who take hard drugs. She says, "People in this business use cocaine and crack, but I never wanted to put that in my body. Why would I? "I tried pot when I was 18 or 19. But it just made me scared to leave the house."
