i get the EXACT same pain thing u are getting.....it feels like its in my lung area.......and it only happens when i inhale......VERY sharp pain.....but very brief also.........every time i get one im scared to inhale for at least 5 seconds after for fear that it will happen again

personally i dont think its cause of the weed........cause ive had these wierd pain things way before i started smoking weed....maybe some kinda growin pains?

iono man........good to see im not tha only one with these lol
