The psychotropic drug addiction is steadily increasing in the subpopulation of the young generation. The objective of this paper is to investigate the degree of psychoticism as a disintegrating personality phenomenon. Psychoticism comprises elements of autism, insensitiveness, aggression, asocialisation. This irregularity in cognitive processes was tested on three groups of people: politoxicomaniacs, psychotic patients and a control group. The DELTA test reported convincingly raised dimensions on the scale of psychoticism: general executive functions (GEI), schyzotypical behaviour (SHD) , paranoia (P), and depression (D), as crucial factors not only for developing addiction but also for achieving long - term and stable abstinence. Apilot study retesting of abstinent persons, has confirmed, after a year's treatment, the change in their behaviour ( by improving all the results on DELTAscale of psychoticism).
