In rats, intrauterine exposure to cannabinoid affected cardiorespiratory function and sleep quality in adulthood

Researchers found that prenatal exposure to synthetic cannabinoid led to cardiovascular problems in female rats and increased respiratory sensitivity to carbon dioxide in male rats. Sleep quality also deteriorated in both sexes, with males experiencing sleep fragmentation due to frequent wakefulness episodes.
