Nobody wants to be called a person but a person who is a person can be noticed on how they behave, and often they consume alcohol and be under the influence of drugs, labelling does happen whereby a person is called an alcoholic or even drug addict by their family, friends and neighbour even before that person is diagnosed as the addict, labelling of a person is a not a right to do, but it indicate that people are aware that there is something which is called alcohol or drug addiction.
