Joan Rivers Gets High With A Friend, Needs Melissa To Pick Them Up On 'Joan & Melissa: Joan Knows Best?' (VIDEO)

Chalk Joan Rivers up as another Californian using marijuana for medicinal purposes, as seen on "Joan & Melissa: Joan Knows Best?" (Tue., 9 p.m. EST on WE). While parked with a friend, Lynne, Joan smoked the medicinal pot she's prescribed to for stress. She's also admitted to using it to help with her recovery from her many plastic surgeries.

Lynne said she was getting a contact high, which must have been pretty intense as when they decided to leave, she couldn't tell if the car was moving yet or not. It was in park.

So Joan decided to call Melissa to the rescue. It must have felt strange for Melissa taking on more of the parental role here, heading off to pick up your mother, who's gotten so high they can't drive themselves home.

Back home, the two women kept up their shenanigans, laughing and giggling as Joan decided they should take a dip in the hot tub in the middle of the night ... fully dressed. When Melissa came out to see what all the commotion was this time, Joan lured her closer so she could grab her daughter and pull her into the hot tub as well.

Catch "Joan & Melissa: Joan Knows Best," Tuesday nights at 9 p.m. EST on WE.
