Actress Drew Barrymore has no regrets about her troublesome past - because her experience with drugs and alcohol has made her more appreciative of life.

The Charlie’s Angels star, 32, rose to Hollywood prominence in 1980 at the tender age of five, but her life soon spiralled out of control and by the time she turned 14, Barrymore had already been in rehab twice for cocaine and alcohol abuse.

But she admits her wildchild ways have made her more cautious of her current Hollywood lifestyle. She says, “(My problems) led me to where I am. I don’t take things for granted.”
