A family history of substance abuse/dependence has a significant impact on the functioning of individuals with substance dependence.

A) trueb) false

True

Explanation:

An individual with substance dependence would have difficulty functioning due to the fact they themselves are addicted to a harmful substance, which would definitely create various obstacles for them to be able to live a normal life. If, in addition to their circumstances, they also have family members who suffered from substance abuse, it would be even harder for them to function - even if they are in recovery, since they would still be around people with substance abuse, increasing the risk of a relapse.
