Kim Kardashian West took to Twitter to immediately squash a vicious rumor accusing her of drug use.

On July 10, Kim posted several Instagram and Snapchat videos promoting her new Kids Supply clothing collection. Many people, though, could only focus on the mysterious powdery substance on a counter behind her.

The Internet was quick to assume that it was cocaine.

Kim smashed that rumor on July 11, tweeting, "I do not play with rumors like this so I'm gonna shut it down real quick. That's sugar from our candy mess from dylan's candy shop."

The reality TV star has never been involved in a drug scandal and has said on many occasions that she doesn't use drugs and rarely drinks.

"I never understand why people get so bothered by what other people choose to do with their lives. I don't do drugs, I hardly drink, I've never committed a crime -- and yet I'm a bad role model for being proud of my body?" she once wrote while defending her naked selfies.

In the past, Khloe Kardashian has also touched on her sister's disinterest in indulging in drugs and alcohol.

"Kimberly does not drink alcohol whatsoever," Khloe told Elle last year. "Pregnant or not, she's just never been into it."

Khloe also shut down rumors in 2015 after there were unsubstantiated reports of cocaine use following Kendall Jenner and Kylie Jenner's graduation party.

"You guys will make up anything," she wrote on Twitter at the time. "No! No one was doing coke at a graduation party in broad daylight with teenagers and 15 production cameras!"

She added, "We aren't as wild as you want to believe. We were taking Jell-O shots though and you have to scrap the rim of the shot glass w ur finger to loosen up the jello in order 2 take it. Just say no to drugs kids! Drugs so not our style."
