During her concert in Amsterdam- Lady Gaga decided to light up marijuana on stage. After a performance, Gaga chilled with her back up dancers at the front of the stage, welcoming gifts that were thrown on the stage by her fans. As she sorted through the gifts, she found a joint and wanted to find out if it was real and lit up! Yep- it was real! She called the drug quote, 'wonderous' and joked that he few puffs that she took wasn't enough to get her high.
