Importantly, the article should solve the following applied tasks: to analyze structural elements of loneliness experience among people with chemical addiction; to describe the internal structure of loneliness experience among people with chemical addiction.

Furthermore, the obtained results suggest that the prevailing dissociated type of loneliness among people with chemical addiction is caused by one’s feeling of loneliness, alienation and, thus, anxiety.
