Singer Miley Cyrus believes that internet is more dangerous for mental health than drugs.

"I put some picture of me smoking weed... on my Instagram because I was brought up in the way that we never thought marijuana was bad," femalefirst.co.uk quoted her as saying.

"You know what hurts your brain? Googling yourself. You know what hurts your brain? Instagram," she added.

"You know what hurts your brain? Reading comments on Facebook."

The "Wrecking ball" hitmaker has been embroiled in a controversy for her provocative dance moves on stage.
