Tuesday night, while shooting the video for his song "Walk Thru," Rich Homie Quan suffered two seizures and hit his head. As a result, he was taken to the hospital for treatment.

For the first time since the incident, Quan is speaking out. In a statement on Thursday (May 8), he stressed that it was neither drugs nor lean, but rather exhaustion and heat, that contributed his medical emergency.

"I just want to thank my fans and everyone who has called concerned about me," the Atlanta rapper said in the statement. "I want to clear up two things, after being in 3 states in 3 days, up early having to shoot my video for 'Walk Thru' and even sleeping in between scenes on top of filming in this humid Atlanta heat, I fainted and hit my head. It's no secret that I do turn up, I don't deny that but I'm not addicted to anything including drugs nor was I leaning at the shoot. The media is gonna put fake stories out there but I just want to let my fans know that I'm good and recovering. The second thing is, I promised I will never stop going in and I mean that."

The rapper's own explanation contradicts a recent report by TMZ -- which he seems to subliminally reference -- which alleges that the rapper was drinking lean on the day of his seizures.

Quan isn't the only one saying it was heat and exhausation, rather than drugs, that caused his collapse. Think It's A Game Entertainment, the rapper's label, offered a similar explanation in a statement issued to MTV News on Wednesday.

"On one of the hottest days of the year in Atlanta, GA, Rapper, Rich Homie Quan experienced heat exhaustion during the filming of his upcoming video 'Walk-Thru,' causing him to initially faint," a rep for the label explained.

It's been a busy week for the 24-year-old, as he was named to XXL's 2014 Freshman class on Monday.
