Paternal snus use in puberty and increased risk for asthma and allergies in offspring: a RHINE/RHINESSA two-generation study

Paternal snus use starting in puberty was associated with a higher risk of asthma and other respiratory and allergic symptoms in offspring. These findings support the hypothesis that exposures in puberty may impact future generations' respiratory health, possibly through epigenetic changes. This highlights the need for research on exposures during this period and actions to prevent habits that could negatively impact future offspring's health.
