The risk of abusing drugs is greater – even for adopted children – if the family environment in which they are raised is dysfunctional, according to a new study conducted by a collaborative team from Virginia Commonwealth University and Lund University in Sweden.
Previous research suggests that drug abuse is strongly influenced by a mix of genetic factors and the environment, including influences of family and peers. That research is primarily based on twin studies and typically involves families that are intact. Relatives that share genes and environment make it difficult to determine if the family dysfunction is linked to the drug abuse or if it is genetics at play. There have been no large-scale adoption studies performed to verify the findings, until now.Share
