Demi Lovato: 'I Couldn't Go 30 Minutes To an Hour Without Cocaine'

Demi Lovato opened up to her drug and alcohol abuse stories.

The 21-year-old singer never talked about her drug abuse but revealed that she used to sneak drugs even on airplanes.

"I couldn't go without 30 minutes to an hour without cocaine and I would bring it on airplanes," she confessed to an interview with Access Hollywood. "I would smuggle it basically and just wait until everyone in first class would go to sleep and I would do it right there. I'd sneak to the bathroom and I'd do it." 

The former Disney star withdrew from the Jonas Brothers' Live in Concert tour in 2010 in order to enter rehab at the young age of 18.

"That's how difficult it got and that was even with somebody [with me]," Lovato continued. "I had a sober companion, somebody who was watching me 24/7 and living with me [and] I was able to hide it from them as well."

"I was going to the airport and I had a Sprite bottle just filled with vodka and it was just 9 in the morning and I was throwing up in the car and this was just to get on a plane to go back to L.A. to the sober living house that I was staying at...I had all the help in the world, but I didn't want it," she revealed on Monday, Dec. 9, from the set of the X Factor. "When I hit that moment I was like, it's no longer fun when you're doing it alone. I've really never talked about this stuff before...I don't know if I should be sharing this."

However, when she was 19, she started to realize her actions. "I think at 19 years old, I had a moment where I was like, 'Oh my God...that is alcoholic behavior. [It's] no longer, I'm young and rebellious and out having fun, it was, wow, I'm one of those people...I gotta get my s--t together,'" she clarified.
