Ed Sheeran has admitted to drinking too much in the past, but on The Jonathan Ross Show Saturday, the singer-songwriter reveals for the first he has also struggled with substance abuse.

“I think you need to, when you get into the industry, adjust to [fame], and I didn’t adjust because I was constantly working on tour. And all the pitfalls that people read about, I just found myself slipping into all of them. Mostly, like, substance abuse,” Sheeran said. “I never touched anything. I started slipping into it, and that’s why I took a year off and buggered off.”

Before he released his third album in March, the “Shape of You” singer went on a year-long hiatus to clear his head. During that time, Sheeran famously got rid of his cell phone and went on a self-imposed social media blackout. “I focused on work, and I can’t work under the influence. I can’t write songs under the influence. I can’t perform under the influence. So, the more I worked, the less [that happened],” Sheeran said (via People). “I’ve worked my whole life to get to where I am, and you can’t lose that over something that you do in your spare time.”
