Why do the sons and daughters of addicts experience a significantly higher likelihood of struggling with addiction later on in life? One could argue that close proximity to substance abuse throughout one's childhood gives one the idea that experimenting with substances is "okay" or "normal."
Suicide attempts are another risk factor for the children of addicted parents. We have known for some time that it is harmful for children to grow up in households where one or more of the parents is using drugs and alcohol. There is a wealth of research data to back that up.
