Lady Gaga says she's addicted to marijuana

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.
