Are you struggling with addiction while raising children? Or maybe you're an adult child wondering if your parent's substance use has affected you even as an adult? Many parents battling addiction believe their struggles remain private—but the reality is far different.
Addiction doesn't just affect the individual; it creates ripple effects that impact children of all ages, from toddlers to grown adults. If you're a parent with an addiction, or if you're the child of someone who struggles with substance use, the effects can linger long after childhood.
In this blog, we’ll explore how addiction affects children, why these impacts don’t disappear even as children grow older, and why seeking help is crucial not only for you but for your entire family's well-being and breaking the cycle.
Let’s start by understanding how addiction affects a child’s development from a scientific perspective.
The brain of a child is easily moulded, especially in the critical years of growth (0-12 years). When a child grows up in an environment affected by addiction—whether it’s due to drug use, alcoholism, or gambling — the stress from the instability can alter brain function in profound ways.
Chronic
stress raises cortisol levels in the brain, which can damage the parts of the brain responsible for memory and learning (hippocampus) and overstimulate the area responsible for emotional regulation (amygdala). Over time, this can contribute to
anxiety,
depression, cognitive decline and even increases
the likelihood of addictive pre-disposition of children later in life due to increased genetics and environmental factors.
When addiction enters a home, it turns family life upside down. Kids never know which version of their parent they'll get from day to day — distant and unavailable or suddenly overbearing. This unpredictability becomes their "normal."
Many children of addicted parents become the parents themselves, taking on responsibilities like making meals, caring for siblings, and managing household emotions when the adults can’t. This phenomenon is known as 'parentification'. It can stunt emotional and social growth, leaving children feeling isolated, guilty, and resentful. The habit of prioritising others over themselves often carries into adulthood, shaping their relationships as they struggle to set boundaries and care for their own needs.
Research also shows that children in these environments face a higher risk of anxiety, depression, and trust issues. They struggle to form healthy relationships because they've never witnessed what healthy relationships should look like.
Moreover, parental addiction often comes hand in hand with larger risk of domestic violence and conflict, which further compounds emotional and behavioural challenges. A study published in Addictive Behaviours (2019) found that children of addicted parents are more likely to develop conduct disorders that influence how they show up at school and even bigger as a member of society.
And perhaps the saddest part? Many children blame themselves for their parent's addiction, thinking they caused it or should be able to fix it. The truth is, children shouldn’t have to act as superheroes just to have a childhood.
Evolutionarily speaking, human survival is tied to strong parental bonding and care. Children are completely dependent on their caregivers for protection, food, and emotional support. When addiction interferes with a parent's ability to provide these essentials, it threatens the child's survival and development.
A child’s developing brain is wired to respond to threats—especially the threat of losing a caregiver. When a parent struggles with addiction, the child’s brain enters survival mode, constantly scanning for danger. Even if their basic needs are met, like food and shelter, the child’s brain doesn’t recognize the difference between an emotionally absent parent due to addiction and one who is physically absent. This heightened state of alertness remains even when there’s no immediate threat, rewiring their brain to stay on edge, which explains why so many children of addicted parents struggle with anxiety or depression later in life.
As addiction psychiatrist Dr. Sarah McLaren explains, “Children of parents with addiction often develop what we call an ‘adaptive survival response’—constantly scanning for danger and preparing for the worst. This protective mechanism, while helpful in their childhood environment, often causes significant problems in adult relationships where such vigilance isn't necessary.”
These early survival responses don’t just go away. The neurological changes are deep, lasting far beyond childhood and making recovery a long-term process.
Many parents mistakenly believe that once their children reach adulthood, they become immune to the effects of growing up in a home affected by addiction. Unfortunately, this is not the case.
Even when adult children have built their own independent lives, the scars from growing up with addiction don’t just fade away. They may have their own careers, families, and social lives, but the emotional burdens of their upbringing continue to affect them in deep ways.
As adults, children of addicted parents still look to their parents for guidance, support, and reassurance. They want to make sense of their past and hope for healing. However, instead of finding understanding and safety, they are often faced with fear, confusion, and frustration as patterns continue. They walk on eggshells, trying to balance caring for their parent while also living their own lives and trying to move away from triggers of the past.
Research consistently shows that adult children of addicted parents face the following lasting effects:
Persistent anxiety, depression and anger: Due to neurological pathway disruptions particularly those related to emotional regulation.
Codependency: Over-caretaking others at the expense of their own well-being.
Fear of vulnerability: They may avoid deep emotional connections, fearing betrayal or abandonment.
Hyper-independence: Since they couldn’t rely on their addicted parent, they may resist depending on others, believing it’s safer to handle everything alone.
Attracting toxic relationships: They may unconsciously seek out relationships that mirror the instability they grew up with, mistaking chaos for love.
Difficulty expressing needs: Since their childhood needs were often ignored, they may struggle to communicate their emotions and desires in relationships.
Higher risk of developing substance use disorders themselves: Genetic and environmental markers are influenced due to a parents alcohol use. While not set in stone, the pathway exists.
These
emotional burdens don’t disappear just because a child reaches adulthood. The patterns established in childhood continue to shape relationships, emotional health, and even parenting styles for years to come.
Recovery from addiction goes beyond just getting sober - it’s about healing relationships and breaking harmful cycles that affect the whole family. When you seek help, you model healthy problem-solving, showing your children that it’s okay to ask for support. Recovery also creates space to mend broken relationships, rebuild trust, and heal emotional wounds caused by addiction. Most importantly, it helps break generational patterns, reducing the risk of addiction and harmful behaviour for your children.
Acknowledging the impact of addiction is the first step. No matter their age, your children are affected, and recognising this reality allows you to move forward. The road to recovery isn’t always easy, but it’s worth it. By taking action today, you’re not just changing your own life—you’re giving your family the chance for healing, stronger relationships, and a healthier future.
