Zac Efron has remained largely quiet in the weeks since reports surfaced alleging he sought treatment for drug abuse issues this past spring.

But on Friday, he shared a photo from a recent visit to Machu Picchu on WhoSay, adding a thank-you note to his fans for their compassion during a difficult time.
"Hey guys! Just returned from an incredible trip to Peru with my dad and wanted to thank you all for your support these past few weeks ... means the world to me," he wrote. "Love you guys! - Z."
Efron has not commented explicitly on reports that he attended an outpatient rehab clinic in March following a relapse into cocaine and ecstasy use, but sources have told outlets including People and E! News that he's now sober and healthy.
Efron, 25, currently appears in "Parkland," which hits theaters next week; he wrapped shooting on Seth Rogen's "Neighbors" after the alleged relapse earlier this year.
Speaking to People, his "Parkland" co-star Marcia Gay Harden observed, "The fact that he's seeking help only says great things about him."
