Addiction to drugs will definitely result in identity crisis. An addict feels that others look at him strangely. When people smile at an addict, he thinks they are laughing at him. An addict may even lose his sense of being alive. He feels ‘dead inside’. Once, a rehabilitated heroin addict told the writer: “Looking out of the window, the sun is shining. The flowers are in bloom. These are signs of a good day.” But pressing his chest, he said, “I don’t feel it here.” Addicts often press their fingers deep into their arms or legs to reassure themselves of their own reality. Their sensations are lost and they look for drug induced sensations.
