Common chemicals in electronics and baby products harm brain development

A recent study published in Environmental Health Perspectives found that exposure to low levels of organophosphate esters can harm brain development in children, affecting IQ, attention, and memory. The chemicals, used as flame retardants and plasticizers in electronics and baby products, have been widely misassumed to be safe.

COVID-19 risk in fully vaccinated individuals with substance use disorders

A recent study found that fully vaccinated individuals with substance use disorders have a significantly higher risk of breakthrough COVID-19 infection compared to the general population. The study, published in World Psychiatry, revealed that patients with cocaine and cannabis use disorder had the highest risks.
