Lady Gaga has come clean with her marijuana use in the past, even freely talking about it during a concert in Amsterdam, but we are now learning that smoking pot became a “need” rather than just a “want”.

Reuters reported that in an interview with gay-magazine Attitude, Gaga admits that she smoked as many as 15 joints a day to help relieve her pain from hip surgery. She also says she went “cold turkey” for weeks and weeks, and thankfully now only joins in on smoking a little bit at night, “just for fun.”

The Daily Mail also reported the singer became dependent on the drug after undergoing hip surgery last February from damage to her cartilage from extensive touring. She cancelled her remaining 25 dates from the Born This Way tour, and delved in writing her latest effort Artpop and explained “I was less drunk and more high on this record. If that makes sense.”

Lady Gaga’s third studio album Artpop will be released Monday November 11. Named the top-earning musician under 30 by Forbes, she earned an estimated $80 million in the past year.
