Latency to consume 1.5g/kg of ethanol for two animals during the 60 days before and after pregnancy. BEC values, measured 90 minutes after the initiation of the drinking session are shown as insets. Pre-pregnancy BECs and latencies are shown in red, post-pregnancy shown in yellow. The subject represented in A drank the daily requirement faster when pregnant compared to the subject represented in B. Inset: The BEC values for the monkey 10309 consistently reflects consumption of the full 1.5 g/kg of ethanol, whereas for monkey 10307, drinking took place over an interval longer than 90 minutes, and as a consequence the 90-minute BEC was lower.
