Actor Zac Efron's friends are worried about him as they suspect he is taking drugs again.
The 26-year-old 'High School Musical' star recently drove miles late at night to go to downtown LA, an area of drug dealers, on the pretext of getting Sushi, a Japanese food, reported TMZ online.
"Zac's a loner. He goes out rarely and the idea of him driving for miles to go to some sushi restaurant in downtown LA after midnight is preposterous," said one of Efron's friends.
The actor's friends have said his bodyguard is actually a convicted drug dealer with whom Efron spends a lot of time despite warnings from friends.
Some of Efon's friends have deserted him in the last few months as they got frustrated to see him slipping off the rails again.
