Final answer:
Substance abuse in the family can lead to intergenerational effects, such as increased risk of physical abuse and neglect in children, as well as the perpetuation of abuse in future generations.
Step-by-step explanation:
Substance abuse in the family can have intergenerational effects, impacting both the current generation and future generations. The most common effects include an increased risk of physical abuse and neglect in children raised by substance abusers. Additionally, other factors such as social isolation, depression, low parental education, and a history of being mistreated as a child contribute to the intergenerational impact. It is important to note that approximately 30 percent of abused children are likely to later abuse their own children.
