Miley Cyrus has defended her decision to publish pictures of her cannabis habit online, insisting she does not promote drug-taking to kids or feature it in her songs.

The Wrecking Ball singer is open about her love of marijuana and even lit up what appeared to be a joint onstage at the MTV Europe Music Awards in Amsterdam, Netherlands in November (13).

Cyrus has also come under fire from anti-drugs campaigners for posting risque snaps related to her habit on her Twitter and Instagram pages, and she was recently targeted for sharing a photo of a giant bong online.

However, the pop star is adamant she is not a bad influence on her young fans, telling Australia's Channel Seven, "I put pictures of me smoking weed, I'm not going to lie, on my Instagram because I was brought up in the way that we never thought marijuana was bad... I don't promote it in my songs... it's not like I'm sitting around telling a bunch of kids to do a bunch of drugs."

Cyrus is adamant nasty comments posted on the Internet are more harmful than her drugs pictures, adding, "You know what hurts your brain? Googling yourself. You know what hurts your brain? Instagram. You know what hurts your brain? Sitting there reading comments on Facebook. I have a 14-year-old sister and I go through her comments and people are calling her a slut and that's a 14-year-old. So I think that's hurting your brain."
