Miley Cyrus criticised for smoking bong

London: The anti-drug campaigners are criticising singer-actress Miley Cyrus after she was caught on camera smoking bong as they feel she is setting a bad example for young fans.

A video that emerged online showed the ‘Hannah Montana’ star puffing on a bong, giggling and smoking controversial psychoactive plant Salvia, reports a website.

Former California State Assemblyman, Anthony Adams, who tried to have the substance banned back in 2007, says the young star is setting a bad example.

"You do incredibly crazy things (under the influence of Salvia). Miley is a star and young kids are going to emulate her behaviour. It`s time for state and federal governments to renew their push toward an outright ban (of this substance)," said Adams

A spokesperson for the US` Drug Enforcement Administration said: "Salvia is a drug of concern. We are taking steps to look further into it..."
