5 Reasons Codependency and Addiction Often Go Hand in Hand


Codependency and addiction are often closely intertwined. This dynamic arises frequently in relationships where one partner is battling an addiction. Both parties feel needed by the other. The addict needs enabling and the codependent needs to feel helpful and responsible for the addict.

Over time, this symbiotic but dysfunctional caretaking and dependency further fuels the addiction entrenches codependent behaviors, erodes healthy boundaries in the relationship, and takes an emotional toll. Counseling approaches suggest each person work toward developing healthy self-care versus depending on the other to feel purpose and self-esteem. The following are five key reasons addiction and codependency often accompany each other.

1. Childhood Issues: Both codependency and addiction often originate from dysfunctional childhoods, especially involving either substance abuse or insecure attachment from parents. Children growing up in these environments fail to form a strong sense of self, self-worth, and coping skills. This lays the groundwork for seeking validation through pleasing and “rescuing” others or self-medicating with substances.  The addict needs to take part in residential treatment near you, while the enabler needs to seek counseling to overcome their need to please and rescue others.

2. Genetics: Genetics can play a role in a person’s susceptibility to addiction. However, environmental factors also substantially contribute. Many people with genetic predispositions toward addiction never develop substance problems if they grow up in stable, nurturing environments.

Codependency often coincides with addiction. Codependents feel an excessive emotional or psychological reliance on their partners. When the partner has an addiction, the codependent’s self-worth becomes enmeshed with the addict staying sober and they try controlling their behavior. The codependent feels if they can just “fix” their partner, everything else will follow. This enables the addiction to continue. Breaking the cycle requires addressing both the addiction and the codependency through counseling, peer support groups, and boundary setting. With a commitment to personal growth, people can overcome addiction and codependency.

3. Poor Self-Care: Codependents and addicts tend to have poor self-care habits. Their own needs are often neglected in favor of satisfying others’ demands or feeding their addiction. Without addressing their personal physical or emotional needs, they remain stuck in unhealthy patterns and at high risk for diseases, mental health issues, and relationship problems.  

4. Repeating Painful Patterns: By unconsciously recreating painful aspects of their childhood, codependents, and addicts can gain a sense of comfort, familiarity, or control even if it also involves suffering. Their dysfunctional relationship dynamics feel normal and reflect their self-perceptions based on past abandonment, criticism, or trauma. Breaking negative patterns requires great self-awareness and motivation for change.  

5. Relationships Built on Neediness: Codependency and addiction relationships involve two people with void-like needs that are temporarily filled by the other person. The codependent person needs to feel needed by the addict who needs something external whether a person or a drug to fill their inner emptiness and dysfunction. This mutual, yet unhealthy form of desperation serves to bond them in an addictive cycle that takes intentional intervention to overcome.

Overall, the most common causes for addiction and codependency overlap relate to childhood trauma, genetic tendencies, poor self-care habits, repeating painful patterns, and relationships built around neediness. Therapies like cognitive-behavioral, group counseling, or 12-step programs can help identify and change the thoughts, behaviors, and relationship skills perpetuating intertwined patterns of codependency and addiction. Understanding these root causes helps people break free of destructive bonds holding them back from health and fulfillment.
