Pop star Miley Cyrus opened up about her decision to quit smoking marijuana on a recent episode of The Tonight Show With Jimmy Fallon. 

"I’ve always been very stoned on your shows. I don’t know if you know this, everybody," she revealed to host Jimmy Fallon. "'Member the last time I was here? I was dressed as a bunny rabbit and then like a cat. There’s a reason for that: I was high."

The "We Can't Stop" singer has been very open about her affinity for weed in the past. In 2013, Cyrus told Rolling Stone, "I think weed is the best drug on earth. One time I smoked a joint with peyote in it, and I saw a wolf howling at the moon. Hollywood is a coke town, but weed is so much better." 

Cyrus explained to Fallon that she really wanted to be sober and present to promote her new record. "I’m actually the most passionate about what I’m doing with this record than I’ve been—I say this every time, but I loved making this record so, so much. And this record at this moment is the most important album that I’ve ever made. So I wanted to make sure that I was super clear in the way I’m talking."

Cyrus said that she used to get stoned and sit at home eating and playing with her pets, but "not doing really anything." She recounted having a nightmare that she would die during her Saturday Night Live monologue because she was too high. She hit the internet to find out if someone could die from smoking too much and was relieved to find out it wasn't possible.

The singer joked, "It’s like no one’s ever died from weed, but no one’s ever smoked as much as I did."

Last month, the 24-year-old artist formerly known as Hannah Montana went on the record with Billboard about her newfound sobriety as she kicked off her promotional tour for "Malibu," her new single. “This is crazy, but I haven’t smoked weed in three weeks! I like to surround myself with people that make me want to get better, more evolved, open. And I was noticing, it’s not the people that are stoned. I want to be super clear and sharp, because I know exactly where I want to be.”
