Answer:
A variety of factors affect development, prenatally and postnatally. A non-biological factor, the drug use by parents before and after child´s birth, affect both.
Step-by-step explanation:
Drug use before, during and after pregnacy problem outcomes form, both individual and environmental reasons. Drug prevention and treatment, traditionally focused on changing individual behaviours have had very limited impact , as the environment hasn´t had necessary change, and the social determinants of drug use have increased, with exacerbating factors that include cognitive limitations, poor parenting and low family socio-economic status, causing the development of children, not receiving the nutrition and stimulation necessary, to be significantly impeded since the very conception, causing genetic predisposition to drug use; in neonatal and infancy, the consequence might be to get a child with difficult temperament , in preschool, children could develop early behavioural and emotional disturbances, such as oppositional defiant disorder or, depression ; in primary school, children could be unable to self-regulate emotions and behaviour ; if they get to high school, children may be exposed to drug-using social contexts.
