What a good role model!

Pot fiend Miley Cyrus once again showed her love of the ganja when she posted an Instagram pic of her smoking what appears to be a joint. After her concert in Pittsburgh on Monday night, the 21-year-old posted the puffed-up pic with the caption, "thankz burgggg."

Wearing a grey hoodie, Miley takes a drag of a rolled up substance while blowing smoke at the camera. The "Wrecking Ball" posted a series of post-concert pics

We get it, Miley -- you smoke pot. You are soooo cool. Do you really need to document every single joint you smoke? That's a lot of photos!

The US leg of her Bangerz tour ends in Chicago on August 14. Then Miss Miley heads to Puerto Rico, the Dominican Republic and Mexico.
