Prenatal cigarette, cannabis exposure may have associations with childhood obesity

Childhood obesity rates continue to rise in the United States, putting kids at risk for asthma, sleep apnea, type 2 diabetes, and other health conditions. Children prenatally exposed to both tobacco and cannabis had a 12 times higher risk for obesity by middle childhood (9–12 years of age) compared to non-exposed children, according to recent research, although more research is needed to determine if other factors account for these findings.
