This is a qualitative study. We interviewed 20 pregnant adolescents, who agreed to participate in this research about the relation between the characteristics of pregnant adolescents and resistance to drugs use. We observed that they had contact will legal and illegal drugs, as well as their decision to reject them, give up or decrease substance use; we also identified a lack of knowledge about reproductive health and body changes. It is important for this population to be able to count on their partner and child, as a support not using addictive toxic substances.
