What is the LD50 of alcohol for humans?

Posted April 9, 2021


Answer

Several studies that have been done show that the LD50 of alcohol for humans is variable but higher than 2g/kg. This is assuming blood ethanol concentrations greater than 300mg/dL. LD50 of alcohol for humans is greatly influenced by gender. Women are more sensitive to alcohol and show higher toxicity at lower consumption levels compared to men.
