Macklemore believes the best way to combat alcoholism is to speak openly about it.

The “Neon Cathedral” rapper spoke about his sobriety while accepting the Stevie Ray Vaughan Award at MusiCares’ 15th annual Concert for Recovery on Thursday.

“The disease doesn’t discriminate,” Macklemore, who had his first drink at 14 and struggled with alcoholism until age 26, said. “It takes the lives of some of the most beautiful people… I’m tired of watching people die from this disease… This disease wants to kill me.”

“I’m not responsible for my disease but I am responsible for what I do about it. I am as sick as my secrets. It’s imperative that we speak up now,” he exclaimed, per Billboard. “We’re in the midst of an epidemic. Today I am not ashamed of who I am. I don’t have to hide my imperfections.”

A number of Macklemore’s fellow celebrities also opened up about their struggles with alcohol. Rob Lowe, who presented the award to Macklemore, said, “When I got sober, I remember thinking that my life is over, I’ll never have fun, I’ll never be cool. I got a call from Steven Tyler. We’d never met. I didn’t know him, but because of this journey, we’re part of a brotherhood.”

Rapper Royce da 5’9″ said, “I’m Ryan Montgomery. I’m an alcoholic. September, I’ll be seven years sober.” Fitz and the Tantrums lead singer Michael Fitzpatrick revealed he was 19 years sober.

The MusiCares Mac Miller Legacy Fund — named in honour of the late “Self Care” rapper — was launched at the event.

Following a tribute to the 26-year-old artist, a number of his hip-hop colleagues remembered him. “I met Mac in 2012. He offered me sanctuary and optimism — things that he was probably missing himself,” Vince Staples shared. “He passed due to some demons and troubles he was facing that we all face. I guess that’s why we’re here today.”
