According to Professor Dr. Zila Sanchez, Head of the Preventive Medicine Department at the Federal University of São Paulo, the transmission of risk regarding substance use is not predetermined by fate but rather exists along a measurable gradient. Dr.
Sanchez noted that parental upbringing plays a significant role in disrupting this potential transmission. The findings stem from a larger research initiative named PREV.ACTION, which is a randomized study conducted at the community level across four municipalities in São Paulo. The study yielded several notable results, with the greatest influence identified as parental abstinence.
The most striking discovery reported was that when parents abstain entirely from substances—including alcohol, tobacco, and cannabis—a substantial 89% of their children also reported no substance use. “This evidence demonstrates that parental behavior is no less critical than parental communication,” stated Dr. Sanchez.
The research suggests that the observable actions of caregivers are a powerful predictor of health outcomes in the next generation. The study underscores the need for interventions that focus not only on counseling but also on modeling healthy habits within the household unit. These results highlight that the most effective preventative measures involve establishing environments where substance use is absent at the parental level.

It’s reassuring to learn that these risk factors are measurable and influenced by upbringing, rather than being purely predetermined fate.
