Miley Cyrus says when she's working, like appearing on "Saturday Night Live" this weekend, she won't be toking, but she's returned to smoking marijuana at other times.

She has mom to thank for that.

The 26-year-old singer told The Sun that after having sworn off the substance last year, her mother, Tish Cyrus, reintroduced her to cannabis.

"My mom got me back on it. When I’m just working I don’t think I function at my highest, most intelligent, most being-able-to-be-as-aware-and-as-present, so I don’t smoke when I work."

Cyrus said bluntly Monday on SiriusXM’s "Radio Andy" that her "mom smokes a lot of weed."

She joked with host Andy Cohen during an appearance to promote her new single with Mark Ronson, "Nothing Breaks Like A Heart," that her mom threatened to quit as her manager and start a weed company.

"My dad’s got a farm and she’s like 'I’m just going to quit everything and grow.' She’s my manager. So if my mom quits everything, that’s quitting me to go home and, like, grow weed. Which doesn’t sound like the best idea. ... My mom could barely keep us alive. She's not going to grow pot."

An 'SNL' stoned nightmare

Cyrus said in a Billboard story in 2017 that she quit weed because she wanted to "be super clear and sharp" as she readied for the release of "Younger Now."

She told Jimmy Fallon on "The Tonight Show" that same year that she had a nightmare about hosting "Saturday Night Live" stoned.

"I had a dream that I would die during my monologue on 'SNL' for some reason; that I would just get so stoned that I just died, which I Googled and that’s never happened," she said.

Cyrus and Ronson are set to appear Saturday on "SNL." Matt Damon is hosting.

Cyrus said of Ronson, "We toke a little. Every now and then, you know."

Last month, Cyrus lost her home to the California wildfires. She shared in a tweet her gratitude that all her loved ones and her animals made it out.

"I am one of the lucky ones," she wrote. "My animals and LOVE OF MY LIFE made it out safely & that’s all that matters right now. My house no longer stands but the memories shared with family & friends stand strong ... Sending so much love and gratitude to the firefighters and LA country Sheriff’s department!"
