In a rather candid but bizarre interview with CNN personality Piers Morgan, Lindsay Lohan (who entered rehab per the court's order this past week) talked in detail about her drug and alcohol use --but her answers aren't what you'd expect.

"Everyone thinks I've done [cocaine] so many times. But I've only done it maybe four or five times in my life," Lohan, 26, told Morgan of her cocaine use (via London Daily Mail). "I don't like it. It reminds me of my dad (Michael Lohan). I took it four times in a period from about the age of 20 to 23, and I got caught twice. ...I felt a little too buzzed -- it made me feel uncomfortable."

When asked about experimenting with other drugs like heroin, the Mean Girls star answered, "It's the truth. I've never taken heroin either, never injected myself with anything, never done LSD. Those things all scare me."

Lohan did, however, admit to trying other drugs, telling Morgan, "Pot, obviously. And ecstasy. I liked that better than the others (giggles). I didn't drink on it, so I was just chilling. It's something that a lot of people experience when they're in college. I just should have known that being in the public eye, someone was bound to say something or try to make some money off it."

When pressed to recall the last time she did a drug, Lohan claims after a long pause, "Probably a year ago ...some pot. But I'm not a stoner."

The troubled actress also claims she doesn't drink a lot, so why has she been court ordered to go to rehab six times? "This is where it gets hard for me to explain. I don't think there's anything wrong with people taking time to just be by themselves. I think people want to see me do that. They will keep saying the same things about me if I don't. I don't think it will be a bad thing for me to be away with myself for three months."

Lohan adds, "I could write the book on rehab. Constantly sending me to rehab is pointless. The first few times I was court-ordered to rehab it was like a joke, like killing time."

Despite her claims that she doesn't have a substance abuse problem, Lohan did admit to taking pills. "I have severe ADD (Attention Deficit Disorder). I can't stand still. So I take Adderall (a prescription drug) for that, it calms me. ...It works well for me," she told Morgan. "Trazodone (a tranquilliser) if I've been travelling and can't sleep from jet lag. But in small doses, I'm not a pill-popper."

As for the worst moment of her life, Lohan confided, "The day I had to turn myself in to jail, and I had to see my mom's face. I spent 12 days inside and I felt utter shock and cried for four days straight."

When asked if she thinks her latest stint in rehab will help her state of mind, the actress added, "Yes. Being in New York has helped me. Just being with my family more, and being able to walk around and have more of a life."
