Gotta give her credit for knowing her mind and body well enough to make a decision like this.
In an interview with the British "Glamour" magazine, Drew says she's prone to ADDICTION . . . so that's why she's avoided plastic surgery, certain hard drugs, and other things that are hard to quit.
She says, "I have an extremely addictive personality. I've never done heroin, and I don't want to get plastic surgery because I feel like they're both very slippery slopes. I feel if I try either, I'm going to be dead really soon."
Drew has had addiction problems with other drugs like cocaine when she was younger, but she's glad she never got work done.
