The susceptibility to drug addiction affects the formation of the students personality. One of the reasons of its appearance is the socialization defects within the family, regrettable attitude of parents to children. The purpose of this article is to identify and investigate the particularities of the parental attitude to the students of the secondary vocational and higher education institutions who have different levels of susceptibility to drug addiction. To analyze the parental attitude two criteria are used in the research: the degree of emotional bond, parents’ attachment to the child (love, acceptance, warmth or emotional rejection and coldness) and the degree of control over his behavior (high—with lots of restrictions and prohibitions; low—the minimum prohibitive tones). They represent three main factors: positive interest vs. hostility, directivity vs. autonomy and inconsistency as a sharp transition from one extreme to another. The research shows that the formation of susceptibility to addiction among the students of the secondary vocational schools is influenced by the particular attitudes of both parents, while university students are mostly affected by their mothers’ attitude. It is found that the particularities of the child-parent relationships in forming susceptibility to addiction affect more the students of the secondary vocational schools than the higher education students. The research data allow to improve the psycho-pedagogical programs aimed at reducing drug addiction susceptibility among students.
