Lady Gaga has revealed details of her marijuana addiction, explaining that at one point, she was smoking 15 to 20 marijuana cigarettes a day, according to news reports. 
 
 "I have been addicted to it and it's ultimately related to anxiety coping and it's a form of self-medication," Gaga said on the Z100 Morning Show, as reported by People magazine. 
 
 Gaga broke her hip earlier this year, causing her to cancel part of her Born This Way tour. 
 
 "I was living on a totally other psychedelic plane, numbing myself completely, and looking back I do see now that some of it had to do with my hip pain," she told Z100, as reported by People. "I didn't know where the pain was coming from so I was just in a lot of pain and very depressed all the time and not really sure why." 
 
 While research has shown that the percentage of people who try marijuana and become addicted to it is small, it is possible to get hooked on the drug. According to the National Institute on Drug Abuse, about 9 percent of marijuana users become dependent on the drug, with that percentage going up for people who begin using the drug in adolescence. 
 
 Comparatively, Scientific American pointed out that in a 1994 study showing that 9 percent of people who've tried marijuana become dependent on it, the numbers are higher for other substances: alcohol is 15 percent, heroin is 23 percent and nicotine is 32 percent. 
 
 Marijuana withdrawal (officially called cannabis withdrawal in the recently released fifth edition of the Diagnostic and Statistical Manual of Mental Disorders) is also sometimes seen in people who stop using marijuana, and is characterized by anxiety, problems sleeping, irritability and aggression, the NIDA reported. And while it's impossible to die from a marijuana overdose like you would from other illicit, dangerous drugs, dependence on marijuana can cause disruptions to people's lives, TIME reported. 
 
 However, TIME pointed out that addiction to marijuana does not look exactly the same as addiction to other illicit drugs, such as heroin. TIME explains: ||||| Demi Lovato is opening up about her battle with cocaine, admitting that she needed the illicit drug so badly that she would smuggle it onto airplanes and sneak to the bathroom to use it. 
 
 During an interview with Access Hollywood, the X Factor coach revealed that she hit rock bottom at 19 — after she had checked into and completed a stint at an Illinois rehab facility in 2010 for “emotional and physical issues.” 
 
 “Something I’ve never talked about before, but with my drug use I could hide it to where I would sneak drugs. I couldn’t go without 30 minutes to an hour without cocaine and I would bring it on airplanes,” Lovato, 21, conceded. 
 
 “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. That’s how difficult it got and that was even with somebody [with me], 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.”

 Lovato says the disease of addiction made her a manipulative and sneaky person. 
 
 “I’m very, very good at manipulating people and that was something that I did in my disease, I would manipulate everyone around me,” she said. 
 
 “There were times I would just continue to lie, so that everything looked OK on the outside.” 
 
 And it wasn’t just cocaine — Lovato also admits to abusing alcohol in the past.

 “I was going to the airport and I had a Sprite bottle just filled with vodka and it was just nine in the morning and I was throwing up in the car and this was just to get on a plane to go back to LA 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 told the outlet. 
 
 “When I hit that moment I was like, it’s no longer fun when you’re doing it alone. 
 
 “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 sh*t together.” 
 
 Lovato’s mother, Dianna, also weighed in during the interview admitting, “I suspected [she was using drugs]. It’s like any other parent, when you see things, when you see signs you don’t want to believe that’s what actually going on. So when they’re telling you that’s not what is going on… you want too badly to believe them and I think for a long time I was in denial.”

 Like Lovato, her mother Dianna also had an eating disorder and once the two sought help they grew closer as a family. 
 
 “I had a terrible eating disorder that I had for many, many years and I didn’t realize it and I had to face up to the fact that I was suffering as well. And a lot of what [Demi] went through with an eating disorder had to do with what she had seen growing up and I also had severe depression and I ended up asking for help actually they did an intervention with me and said, ‘Mom, you need to get help,’” Dianna admitted. 
 
 “The issue I had was definitely a mental health issue and I also had to get help for my struggles as well as she did and then once I did, we became closer as mother and daughter, [and] we also became well as a family.” 
 
 “I’m so… proud of her it makes me so happy,” Lovato said. “I love her so much.”
– Lady Gaga is (or was) addicted to marijuana, she revealed in a radio interview recently, People reports. "It's ultimately related to anxiety coping and it's a form of self-medication," Gaga told Elvis Duran and the Z100 Morning Show. "I was smoking up to 15 to 20 marijuana cigarettes a day with no tobacco." She says she used the pot to deal with her recent hip injury, as well as other stresses related to her fame. "The truth is that I can break, and I did. I was not very good at breaking," she said. "I lost everything that I love. I was in a wheelchair for six months. I did a lot of drugs and took a lot of pills." "The truth is that it is very hard to be famous," she continued. "It's wonderful to be famous because I have amazing fans. But it is very, very hard to go out into the world when you are not feeling happy and act like you are." She added that she's struggled with addiction, to various substances, from a young age, but she's now fighting it and wants to make new music without being under the influence of anything. (If you're skeptical of her addiction claim, the Huffington Post points out that it is possible to become dependent on the drug, though few people do.) Gaga also recently told Attitude magazine she's seeing a shrink to help her deal, the New York Daily News reports.
