Lady GaGa dealt with pain from her hip injury by smoking marijuana. In an interview with Attitude magazine, the Mother Monster revealed that she smoked 15 joints of marijuana a day because of the intense pain.

"I was just numbing, numbing, numbing myself then sleeping it off, then getting on stage, killing it in pain, then getting off and smoking, smoking, smoking, not knowing what pain was," she said, as quoted by Daily Mail. "F**k if I know what hurts the most, you know? I would break the habit and it would sneak back in and I would break it and sneak back in."

The singer thought that her experiences as a struggling artist back then contributed to the habit. "Yeah, it's trauma. I went through terrible experiences early in my career climbing through swine and swine of men in the music industry - just trying to get somebody to listen to my music and take me seriously as a songwriter instead of trying to get me to b*** them," she said.

The "Applause" singer suffered a labral tear of her right hip in February and underwent a surgery, resulting in the cancellation of many dates on "Born This Way Ball Tour". The 27-year-old singer was forced to use a wheelchair as she recovered. Her latest album "ARTPOP" is due out on November 11.
