Lol are you writing a fantasy novel. When GD was in the party a Japanese man came to him and said he was his fan and gave him a cigarette while they were enjoying the party and someone took a picture of it and posted online. So, when GD was tested even tho the result came positive but amount was almost equal to 3-4 puff. which matched his story. That's why he never got trialed this is the actual story.
