10. Mischa Barton
Mischa Barton is one actress that you never think will use drugs. She just seem so innocent, simple and just sweet. Well, we cannot really judge the book by its cover as Mischa has been through that drug phase too but she is now recovering from it.
11. Tara Reid
Tara Reid look like such a sweetheart in 2000. However, she underwent that “drug use” phase that many celebrities have been through. Thankfully, she got over that phase but she never looked the same way again. Let’s just hope she was able to regain that youthful glow.
12. Courtney Love
Courtney actually admitted to using all types of drugs including alcohol and the prescribed ones. Now, she is sober but she is well aware that her face changed a lot during her drug use phase. She may be happy when she was using drugs but it will have consequences that will stay with you forever.
