In-Studio photos of Macklemore here.

Macklemore had to have a series drug problem but he's been sober for sometime now. With his newfound celebrity, he's resisted the urge to engage in drugs in social settings but the real challenge comes when he is home alone. 

"That's not what's challenging for me. It's when I get home off the road and I'm alone. I'm on my couch and I'm thinking and I wanna stop thinking. To me, that's when I'm susceptible to relapsing."

Macklemore explains that when he gets back home from touring are the times when he has to demonstarate the most amount of will power.

"You know when it was the hardest for me [to not relapse]? When "Thrift Shop" was a hit and I was the "Thrift Shop" guy. That's when I was like the pressure is weighing on me."
