Substance abuse can have a significant impact on relationships. Individuals who struggle with substance abuse may experience strained relationships with family members, friends, and romantic partners. Substance abuse can lead to conflicts, mistrust, and broken promises, which can erode the foundation of a relationship over time. It can also cause emotional and psychological distress to the loved ones of the individual struggling with substance abuse. Family members and friends may feel helpless, frustrated, and angry, which can damage their relationship with the individual. In some cases, substance abuse can lead to domestic violence, which can further exacerbate the negative effects of substance abuse on relationships.
