Kris Jenner gets high with her mother Mary Jo in the name of pain relief

Some people enjoy a nice afternoon tea with their elderly parents - not Kris Jenner, she happily shares some drug infused treats with hers.

In a sneak peak of this week's episode of Keeping Up With The Kardashians, the 58-year-old star gets high with her mother Mary Jo in the name of pain relief.

As the 70-something grandmother suffers from severe back pain she has been prescribed medical marijuana so Mary Jo suggests her daughter indulges as well.

The great grandmother says in the video: 'I think you should do it with me. It is not a bad thing, they have obviously made it medicinally for people with AIDS and cancer and it's a good thing.'

Wanting to support her mother Kris agrees to try the bears explaining: 'I'm not against anybody getting some pain relief from medical marijuana, that's the whole point here.

'So if it helps my neck and she's asking me to do it with her, I'm here to support and I'll do it this one time. I never thought in a million years I'd be doing this with MJ.'

Cheersing their gummy bears together, Kris says: 'I don't like to drink alone so I'm sure you don't like doing this alone.'

Fast forward are few minutes and the two ladies are predictably giggling and laying into whatever snacks they can get their hands on.

While they were having a ball, Kris' estranged husband Bruce was certainly not impressed.

Trying to explain through fits of laughter, the momager says: 'We thought it be a good idea for MJ to try out some MJ, you know what I'm saying? You know what marijuana is?'

The former Olympian certainly does: 'Yes, I do, and I won't have it in this house. I want that s**t out of the house.'

Explaining to the camera Bruce says: 'I hate drugs and for Kris and her mom to be treating this like a big joke really, really upsets me.'

Keeping Up With The Kardashians airs on E! on Sunday night.
