Grimes has decided to dissociate herself from drugs for the sake of her fans.
The 27-year-old Canadian singer has seen many of her close friends die from narcotic use over the years and now she's decided to make a stand by not letting substances ruin her image as an artist because she's a role model for teenagers.
Speaking to ES magazine she said: "I've had a couple of very close friends die related to complications due to drug abuse. It can't be part of my life any more.
" And I don't want it to be part of Grimes either, because whether I like it or not, people do what I do -- or think what I do is cool. If you meet kids after a show and they're like, 'Yeah, Grimes, I want to do drugs with you.' It's f***ing scary when 13 year olds are like that. You're like: 'Oh my God, I'm like ruining the world' "'
Meanwhile, Grimes - whose real name is Claire Botcher - also admitted she is "allergic" to the idea of her music and work as a producer being judged on appearance because until now she thought she was "ugly".
She explained: "I was always a very ugly person until recently. I had terrible hair and bad skin. So the whole thing is pretty odd.
"My self-identity is so strongly based on my abilities as an artist and as a producer and an engineer, I'm allergic to the idea of ever being evaluated on my physical appearance.
"When people are like, 'Marry me, Grimes' -- I'm like, AGHHHGH. Like I can't... it's every day. Marry me, marry me. It's so weird."
