Gangs in the United States include several types of groups, including national street gangs, local street gangs, prison gangs, motorcycle gangs, and ethnic and organized crime gangs. Approximately 1.4 million people were part of gangs as of 2011, and more than 33,000 gangs were active in the United States.
Many American gangs began, and still exist, in urban areas. In many cases, national street gangs originated in major cities such as Los Angeles, Chicago, Miami and New York, and they later migrated to other American cities such as Atlanta, Memphis, Orlando, Houston, and Detroit.
Law enforcement broadly refers to any system by which some members of society act in an organized manner to enforce the law by discovering, deterring, rehabilitating or punishing persons who violate the rules and norms governing that society. Although the term may encompass entities such as courts and prisons, it is most frequently applied to those who directly engage in patrols or surveillance to dissuade and discover criminal activity, and those who investigate crimes and apprehend offenders. Furthermore, although law enforcement may be most concerned with the prevention and punishment of crimes, organizations exist to discourage a wide variety of non-criminal violations of rules and norms, effected through the imposition of less severe consequences.
United Blood Nation, simply known as U.B.N is a prison gang formed in 1993 within the New York City jail system by leader Omar Portee on Rikers Island's George Mochen Detention Center. G.M.D.C was used to segregate problem inmates from the rest of the detention center. They are one of the largest gangs in New York City.
Members of this gang were known for burning three triangular shape circles on their upper right arm to show affiliation to it. Some members would tattoo a bulldog's face on their right hand, the numbers 031 and letters M.O.B to identify themselves from outsiders also.

Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
