The research was conducted on a sample of three clinical cases of individuals addicted to psychoactive substances, residing at the Wasit Center for Addiction Treatment in Ain Temouchent Province, aged between 17 and 30 years. _A set of psychological tools was used, including semi-structured interviews, observation, tests, and psychological scales. Among them were the Big Five Personality Traits Scale by Costa and McCrae, and the Thematic Apperception Test (TAT) for adults, aiming to identify shared traits and repressed internal conflicts. _The study concluded that addicts who commit crimes under the influence of psychoactive substances exhibit moderate to high levels of neurotic traits such as tension, anxiety, anger, tendency to give up, self-consciousness, lack of self-confidence, and guilt. In some cases, traits such as conscientiousness, extraversion, and agreeableness were also dominant. _The TAT results for the three cases revealed a borderline psychological structure, marked by weak identity organization and the use of primitive defense mechanisms such as projection, splitting, and denial. The cases showed impaired symbolic representation and imagination, along with blurred psychological boundaries between self and others. This reflects a clear psychological fragility that necessitates therapeutic intervention to enhance internal integration and construct a coherent inner narrativeotherCriminal personality , Neuroticism ,Psychoactive substances , Addiction , Criminal , Addicالشخصية الاجرامية؛العصابية؛المؤثرات العقلية؛الادمان؛مجرم؛مدمنThesis
