Rohan is 29. He hasn’t touched alcohol in three years, and he still remembers the exact moment he decided to stop; standing in his kitchen at 11 pm, glass in hand, realising he was pouring himself the same drink, at the same hour, with the same silence around him, that his father used to pour every night of Rohan’s childhood.
He wasn’t trying to become his father. He just woke up one day and found he already had.
This is one of the quieters, less-discussed truths about addiction in India: it rarely starts in a vacuum. It moves through families, sometimes through genes, sometimes through what a child learns to consider normal, and often through both at once. Talking about this openly isn’t about blaming parents or grandparents. It’s about understanding the pattern well enough to interrupt it, because interrupting it is possible.
Addiction has a genetic component, and the research on this is now fairly settled. Global studies estimate that genetics account for roughly 40 to 60% of a person’s overall risk of developing addiction, with the rest shaped by environment; home life, peer influence, stress exposure and access to substances. This doesn’t mean a child of an alcoholic is destined to become one. It means their starting risk is meaningfully higher before anything else in their life has happened.
That elevated risk shows up clearly in the data. Research on children of alcoholics has found they are around four times more likely to develop alcohol dependence themselves compared to the general population. A study from St. John’s Medical College in Bangalore, looking specifically at Indian men being treated for alcohol dependence, found that family history density essentially, how many close relatives also struggled with alcohol was directly linked to how severe a person’s own alcoholism became. The more addiction in the family tree, the harder the pattern tends to hit.
None of this is destiny. Genetics load the gun; environment and opportunity for support decide a great deal of what happens next.
Children raised in homes where a parent drinks heavily or uses substances absorb far more than genes. They absorb a template for what a family under stress looks like unpredictability, walking on eggshells, learning to manage a parent’s mood before managing their own feelings, sometimes stepping into a caretaking role well before they’re old enough for it.
This is where the idea of intergenerational trauma and addiction becomes important to understand. A landmark study by the US Centers for Disease Control and Kaiser Permanente known as the Adverse Childhood Experiences (ACE) study, found that people who experienced four or more categories of childhood adversity, including growing up with a substance-using parent, faced a four to twelvefold increase in risk for alcohol or drug problems in adulthood. Growing up specifically in a household affected by substance abuse was linked to being over three times more likely to misuse substances as an adult, independent of other risk factors.
In an Indian context, this often takes a particular shape. A child grows up learning that conflict is handled through silence or shouting, that feelings aren’t discussed, that a parent’s drinking is something the whole family quietly organises itself around. Nobody sits the child down and teaches them this. They learn it the way children learn everything that matters by watching, every single day, what the adults around them treat as normal.
At Veda Rehabilitation and Wellness, family history comes up constantly in early conversations with clients and their relatives, and a few patterns repeat often enough to be worth naming.
Adult children of parents with alcohol use disorder frequently describe a strange, delayed recognition, not that they’re repeating their parent’s exact behaviour, but that they’re repeating the emotional logic behind it. Using alcohol to avoid conflict. Using it to sleep. Using it because feeling nothing seems safer than feeling something specific.
Siblings in the same family often don’t respond identically. One child may become the addicted parent’s mirror; another may swing hard in the opposite direction, avoiding alcohol entirely out of a kind of learned fear, sometimes at the cost of never really processing what happened at home. Both responses come from the same root.
And the pattern isn’t limited to alcohol. Families with a history of anxiety, depression or unaddressed trauma often see the next generation reach for something else entirely prescription sedatives, compulsive gaming, digital dependency, because the underlying wound was never about the specific substance. It was about not having safe, healthy ways to handle difficult emotions.
This is the part that matters most, and it’s the part that gets lost when generational addiction is discussed only in terms of risk. Having a family history of addiction increases vulnerability. It does not guarantee an outcome.
Several things reliably interrupt the pattern, and none of them require a person to be a mental health expert.
Naming what happened, honestly, is usually the first real step. Many adults from these families spend years minimising their childhood, “it wasn’t that bad,” “lots of people had it worse”, because naming it feels disloyal. But you can’t interrupt a pattern you haven’t allowed yourself to see clearly.
Building emotional vocabulary matters more than it sounds like it should. Children who grow up in addicted households often reach adulthood without ever having learned how to say “I’m anxious” or “I’m overwhelmed” out loud. Therapy, family counselling or even structured conversations within the family can rebuild that muscle from scratch.
Early support changes outcomes dramatically. A young adult who recognises the family pattern in their twenties and seeks help then is in a fundamentally different position than someone who waits until their forties, after a decade of consequences has already piled up.
And treating the whole family not just the person who is struggling tends to be more effective than treating addiction in isolation. Integrated care that addresses mental health and addiction together, rather than one after the other, reflects how these conditions often occur together in real families, generation after generation.
If there is one honest thing to say to a family currently living inside this pattern, it’s this, the goal isn’t to become a family with no history. Every family that has faced addiction has that history now, permanently. The goal is to become a family where the history stops repeating itself in the next generation.
That takes more than willpower from one person. It takes older family members being willing to talk honestly about what happened, younger family members being given permission to seek help without shame, and where addiction and mental health conditions are already present, professional care that treats both together, with enough structure and follow-up to actually hold.
At Veda Rehabilitation and Wellness, families dealing with exactly this pattern are one of the more common reasons people reach out, not always for the person currently struggling, but sometimes for an adult child trying to make sense of what they grew up with, or a parent trying to give their own children a different childhood than the one they had. Veda’s approach treats addiction and any co-occurring mental health condition together from the first assessment, because in families like these, the two are rarely separate stories.
Both play a role. Research suggests genetics account for roughly 40 to 60% of a person’s addiction risk, with environment, upbringing and life stress shaping the rest. A family history of addiction raises vulnerability; it doesn’t make addiction certain.
Studies indicate children of alcoholics are around four times more likely to develop alcohol dependence than people without that family history. An Indian study on alcohol-dependent men also found that a stronger family history was linked to more severe alcoholism.
Intergenerational trauma refers to emotional and psychological patterns; unprocessed stress, unhealthy coping habits, unresolved pain that get passed from one generation to the next, often without anyone intending it. In families affected by addiction, this frequently shows up as children learning unhealthy ways to manage difficult emotions, which raises their own risk later in life.
Yes. A family history increases risk, but it doesn’t determine outcome. Early recognition, honest conversations within the family, learning healthier ways to process emotion, and professional treatment when needed all meaningfully lower the risk for the next generation.
Involving the family generally leads to better outcomes. Addiction rarely develops or heals in isolation, and family involvement helps address the patterns and dynamics that contributed to it in the first place.
There’s no fixed age, but earlier awareness is better. Young adults who recognise a family pattern and seek support in their twenties are generally in a stronger position than those who wait until years of consequences have accumulated.
