Q. Where can I find sources on the effects of substance abuse by parents on their children?

Your best bet is our social science databases (link below). In them you'll find articles, books, eBooks and streaming media.

An effective search in most of these resources would probably be "substance abuse" AND children. Most sources retrieved will be discussing the substance abuse of the parents.
