However, women who breastfed exclusively had lower postpartum vitamin D levels, which may be related to the duration of breastfeeding rather than a causal link.
A recent study by Indiana University found that the state spends significantly more on health care-related consequences of substance abuse compared to its prevention initiatives. This means that for every dollar invested in treatment and intervention programs, only a small fraction is dedicated to preventing substance abuse.
