The study titled, “Effect of Electronic cigarette aerosol Exposure During Gestation and Lactation on Learning and Memory of Adult Male Offspring Rats” is to be published in Physiology & Behavior. The researchers exposed rats to either fresh air or e-cig vapour, for one hour daily during their gestational period as well as days 4-21 of lactation. [...] The results indicated that relative to fresh air exposure, aerosol exposure during the gestation and lactation perios impaired long-term memory in adult offspring (P<0.05). To this effect, the researchers concluded that vaping during pregnancy should be discouraged.
