Since at least the 1970s, researchers in Texas have been calling substance use a "family affair." A study by the Texas Research Institute's Drug Abuse Clinic compared two groups of families similar to each other in every aspect – from socio-economic status to ethnic background. The only difference was that one group had at least one family member who was an addict. The study found fathers dealing with drugs were critical and arrogant, mothers were disenfranchised and children were bitter and resentful.
That was in the '70s, but the story is not so different today.
