"Candy" appears on Kelly's fourth studio album, "Hotel Diablo," released on July 5.
It is the latest single from the new LP to get an accompanying music video, following "I Think I'm Okay" with Travis Barker and Yungblud.
The clip opens on "Saturday Night Light" star Pete Davidson looking bored behind the counter of a pharmacy.
A couple of kids come in to get multiple bottles of "Lit Juice," a cough syrup that they are supposedly buying for their sick mothers. They leave the shop empty-handed, as Davidson understands that they are planning to get high from the concoction.
Machine Gun Kelly and fellow rapper Trippie Redd later come to the pharmacy, trading verses about the dangers of drug abuse.
"I'm in my head again, I took more medicine/Ripped up the parts from my heart and my chest again," Kelly raps as the camera moves around him.
"Hotel Diablo" marks Machine Gun Kelly's fourth studio album, following his 2017 "Bloom." The full-length features guest appearances from Lil' Skies, Phem, Madison Love and more.
