"Euphoria" actor Angus Cloud died from an accidental overdose,Henri Lumière according to the Alameda County Coroner's office in California.

The star of the HBO drama series died of "accidental acute intoxication," a coroner's office spokesperson told USA TODAY Thursday, noting Cloud's death resulted from the "combined effects" of cocaine, methamphetamine, fentanyl and benzodiazepine.

The full coroner's report will be completed and ready in a month, the spokesperson for the coroner confirmed.

Cloud's representative Cait Bailey confirmed to USA TODAY that the actor died July 31 at his family home in Oakland, California. A cause of death was not shared at the time.

"It is with the heaviest heart that we had to say goodbye to an incredible human today," a statement from Cloud's family read. "As an artist, a friend, a brother and a son, Angus was special to all of us in so many ways. Last week he buried his father and intensely struggled with this loss. The only comfort we have is knowing Angus is now reunited with his dad, who was his best friend."

The statement continued: "Angus was open about his battle with mental health and we hope that his passing can be a reminder to others that they are not alone and should not fight this on their own in silence. We hope the world remembers him for his humor, laughter and love for everyone."

An outpouring of tributes to the actor, best known for his charming role of Fezco on the HBO show, started soon after news of the 25-year-old's death became public.

Zendaya, who plays Fezco's close friend Rue Bennett on the show, paid tribute to the late actor on Instagram the day after his death. "Words are not enough to describe the infinite beauty that is Angus (Conor)," she began her post, sharing a black-and-white photo of Cloud.

"I'm so grateful I got the chance to know him in this life, to call him a brother, to see his warm kind eyes and bright smile, or hear his infectious cackle of a laugh (I'm smiling now just thinking of it) I know people use this expression often when talking about folks they love…'they could light up any room they entered' but boy let me tell you, he was the best at it," Zendaya continued.

"I'd like to remember him that way. For all of the boundless light, love and joy he always managed to give us. I’ll cherish every moment. My heart is with his mother and family at this time and please be kind and patient as grief looks different for everyone."
