Miley Cyrus reveals her mum's marijuana is extremely potent

The singer confessed that while she had introduced Tish Cyrus to the drug, her mother's marijuana supply was now too strong for her to enjoy.

"I will randomly take one small puff off my mom's joint - pretty much never - because it's way too strong," Miley, 31, told David Letterman on his podcast My Next Guest Needs No Introduction. "I don't smoke my mom's weed anymore."

She explained that a recent smoking encounter with Tish, 57, had left her feeling disoriented and unable to drive.

"The last time I smoked her weed was a couple weeks ago, and I did walk in and take the smallest puff ever," Miley revealed, adding the experience left her too scared to get behind the wheel of a car for, "what felt like three days".

"I didn't know who I was," she said.

Tish's stash is so potent, Miley said, that it sent rapper Wiz Khalifa, 36, into a panic spiral.

"My mom gave Wiz Khalifa a panic attack 'cause her weed was too heavy," Miley laughed.

Ironically, Miley said, she had been the one to introduce Tish to the drug - which is legal in California, where they both live.

"She goes, 'OK, but just don't tell anybody 'cause I'm a good Christian woman'," Miley recalled, of the time she first encouraged Tish to try marijuana. "But she loved it. She had the best time and she smoked weed ever since."
