Lady Gaga was addicted to marijuana.
The Applause hitmaker has made no secret of the fact that she has used the drug in the past, but now admits she became dependent on smoking weed, often consuming between 15-20 cigarettes a day.
She told The Z100 Morning Show: "I have been addicted to it and it's ultimately related to anxiety coping and it's a form of self-medication and I was smoking up to 15-20 marijuana cigarettes a day with no tobacco."
The 27-year-old singer suffered an agonising hip injury which caused her to end her Born This Way Ball world tour earlier this year and she puts her addiction down to this difficult period in her life.
She explained: "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. 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."
