The Little Monster leader had long been a weed aficionado and even smoked a joint on stage during a concert in Amsterdam last year. But as her hip injury grew worse on her Born This Way Ball tour, the singer revealed that she was smoking up to 15 joints per day to help numb the 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 the pain was," she admitted last month. Gaga underwent hip surgery last February, but found herself unable to kick her weed habit. She credits performance artist Marina Abramovic with helping her to get sober last summer on a bizarre retreat, which included being sent into the woods blindfolded to help find her “way home.” Although the singer admits to now smoking “a little bit,” she said this is the “soberest” she’s been in years.
