Lady Gaga revealed on the Elvis Duran radio show in November 2013 that she’s been quietly battling an addiction to marijuana. “I had to stop (smoking pot),” the Mother Monster said. “I was addicted to it. … Although I think it’s the best drug to choose from when you’re playing around and experimenting, I just want young kids to know that you actually can become addicted to it, and it’s ultimately … a form of self-medication. I was smoking 15-20 marijuana cigarettes a day with no tobacco.”
