Someone needs to help Bieber before he gets into serious legal trouble, as the incidents are piling up and some are more serious than others (see: marijuana pics). Every few days it's something else. Things are going wrong for Bieber and he needs to remember, according to studies, he is genetically predisposed to drug and alcohol problems, due to the issues his parents have trouble with regarding substance abuse.
Therefore, it's best to avoid drug use and alcohol abuse, as one is not in charge of one's faculties under said circumstances. Getting into an environment with so-called friends, who have booze flowing and drugs in heavy supply, is not a good idea or place to be. You need to cut some of those friends loose, because they are dragging you down. One of these incidents is going to result in tragedy if you do not stop yourself in time.
