Zac Efron's drug addictions were actually revealed last month, and it was also revealed that Zac has already been to rehab twice to deal with them. However, rather than shun him or abandon him, most of Zac's fans have steadfastly stick by their idol.

Zac is proving to his fans that their support doesn't go unnoticed by posting a picture of himself in Peru, with the captions saying, "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. Love you guys! - Z."
Apart from that, Zac hasn't commented at all about the controversies or his decision to go to rehab. What's important now is that he looks healthy and happy, and he doesn't look like someone who's still living with those addictions.
