Substance use rarely appears out of nowhere in a child’s life. It can grow inside homes actually, shaped by daily routines, stress, silence, and example. A large study published in Addictive Behaviour takes a deeper dive at this link. It asks a hard but hopeful question: can the way adult parents soften, or even stop, the passing down of substance use from one generation to the next? The answer is not simple, but it might be reassuring for families trying to do better, even when the odds feel stacked against them.
How substance use passes from parent to child
Children learn long before anyone explains things to them. They notice how adults relax, cope, celebrate, or escape. The study followed over 4,000 adolescents and their parents in Brazil and found a strong alignment between parent and child substance use patterns, especially when parents did not use substances at all. This shows how powerful everyday modeling can be.But the study also makes one thing clear: similarity does not mean destiny. Even in homes where parents used substances, children did not automatically follow the same path. Something else mattered, and it mattered a lot.
The emotional climate at home matters more than rules alone
Parenting is not just about setting limits. It is also about warmth, listening, and consistency. The research looked closely at 4 parenting styles: authoritative, authoritarian, permissive, and neglectful.Homes with a clear structure and emotional connection stood out. In these families, children were less likely to drift into risky patterns like using multiple substances. This suggests that how boundaries are delivered can be just as important as the boundaries themselves.
Why authoritative parenting stood out in the study
The strongest protective impact was demonstrated by authoritative parenting. This approach aims to strike a balance between empathy, explanation, and strict regulations.According to the study, even if their parents were high-risk substance users, teenagers raised in this manner were less likely to use substances. It shows that children react not only to how adults interact with them but also to what adults do.
The mixed message of authoritarian parenting
Authoritarian parenting, which relies heavily on strict control and obedience, did reduce the risk of adolescents using multiple substances. On the surface, this may seem positive.However, the same style was linked to a higher chance of alcohol use being passed from parent to child. This points to a hidden cost. Fear-based control may stop some behaviors, but it does not always help children build healthy decision-making skills. Alcohol, being socially visible and often normalised, may slip through these rigid systems more easily.
When absence speaks louder than advice
Permissive and neglectful parenting styles showed no protective effect in the study. In these homes, rules were either unclear or emotional involvement was low.Children growing up in such environments may feel free, but they are also unanchored. Without guidance or attention, they may turn to peers or substances to fill emotional gaps.Supporting parents in developing healthier parenting approaches may have long-term benefits that extend well beyond the present generation.Read also: Could humans ever live underwater?Disclaimer: This article is for informational purposes only and is based on findings from a specific research study.
