Lindsay Lohan
Lohan once told Oprah Winfrey that she used cocaine 10 to 15 times per day. It’s no wonder that she’s been to rehab more than almost everybody else on this list. She’s received multiple court orders and also checked herself into different facilities to deal with her addiction.
However, Lohan proved that rehab isn’t a miracle cure. She rejected it several times because she thought it was a waste of time. This shows that patients, famous or not, must enter with an open mind and want to become better. Everyone knows about Lohan’s harrowing struggles with substance abuse and her attempt to make it back to stardom (via Daily Beast).
