Lindsay Lohan is coming clean about her past cocaine use, claiming her estranged father Michael, a former drug addict, first got her curious about the drug.
"I was only aware of cocaine because of my dad," she tells Britain's The Sun in a new interview. "I was terrified of it. But I tried it because I was stubborn, stupid, and wanted to see what it was like."
Police found Lohan, 23, to be in possession of cocaine in two separate DUI incidents in 2007. She went to rehab three times.
"It's not something I ever want to do again," she says of the drug. "It made me feel like s***. It became uninteresting to me. I'm hyper anyway and I have that kind of personality so I don't need something like that."
In 2007, after her father began speaking negatively about her in the press, Lohan says she hit "rock bottom" and began abusing "alcohol, cocaine and mind-altering substances" to "mask" her problems.
She still cringes when looking back on one night when she took the sleeping aid Ambien and climbed into a bathtub.
"I'd run a bath and fallen asleep on the floor and the bath had overflowed," she recalls. "When I woke up, I was so scared. I called my therapist and said, 'Can I just go somewhere for a month?'" she says. "'I'm around bad people and I need to take care of myself.' I was terrified, so I put myself in."
Adds the actress, "There was a point when I didn't know how to say 'No' and I was trying to please everyone. "I was doing pop and making films. I was young and thought I could go out, have fun, then go on set and record. I ran myself down and I lost track of who I was."
These days, she says she's "in a place where I don't need to use anything and I can feel emotions because I choose to."
Though she says she is still allowed to "drink ... I know my limits. There are certain situations where I have obligations. There's no reason to (drink) because I don't want to feel like s*** in the morning."
Says Lohan, "I've made some dreadful mistakes but learned from them - that has probably saved my life."
