Kris Jenner was worried that Kim would become a "crazy drug addict" after she revealed that she had taken ecstasy.
Kim who admitted on Keeping Up with the Kardashians that she experimented with ecstasy has a close relationship with her mother and was always been able to tell her anything.
After her confession, she agreed to stop taking the pills because she didn't want to ruin her future.
Speaking to Busy Phillipps on 'Busy Tonight', she said: "I would tell my mom everything, we always had such a close relationship."
"So I would come home and be like, 'Oh my god, mom, I did ecstasy last night.'
"She was sitting on top of the washing machine, and she like jumped up on it, and we were sitting in the hallway by the garage... and she was like, 'You, one day, you're not going to be able to have babies, you can't do this, you're going to ruin yourself!' Like she was so upset."
"She never did drugs, so she was just so upset thinking that I was going to turn into something, you know, and just be this crazy drug addict."
"And I just was like, 'You know what? She's so right, I'm so over it. Like, this is so not me. And I just never did anything again."
Kim who is a mother to North, 5, Saint, t3, and 11-month-old Chicago shocked her half-sister Kendall Jenner and Scott Disick, when she revealed her past ecstasy use, and Kim can understand why, because they view her as someone who wouldn't.
She said: "People that were close to me, that obviously know that life of mine, they're like, 'I can't believe you said that.' And I was like, 'Well, I mean, I never really hide anything.'
"[I think] it's just weird to people that I've done ecstasy but I don't drink, I don't smoke weed, I don't do anything." So it's weird to have done that."
During the scenes on 'KUWTK', Kim admitted that she made bad choices while on ecstasy that included marrying music producer Damon Thomas in 2000, and shooting her infamous sex tape with Ray J.
She said: "I got married on ecstasy. The first time. I did ecstasy once, I got married. I did it again and I made a sex tape. Like, everything bad would happen."
