Can Drug Addiction Be Passed Down? Substance use disorder often runs in families. That’s because there is an inherited component, meaning it can pass from parent to child by way of genes. For this reason, your family history offers clues about how vulnerable to addiction you might be. For example, if you have a close relative that’s affected, it’s a clue to be extra careful. Researchers use family histories too. They compare DNA sequences of family members to identify genes involved in addiction. First, they divide the family into two groups: affected and unaffected. Next, the researchers look for segments of chromosomes that are more common in affected people compared to unaffected. They narrow the segments down to specific genes to study further. Because people have complex and varied lives, in-depth studies are often done using animals in a controlled lab setting.
