Alcohol or Caffeine; What Would Kill You First? A Study into Common Alcoholic Beverages Consumed by University Students.

Matthew Johnson, George Watson, Devpreet Surae


Jägerbombs and VKs contain very high levels of alcohol and caffeine. By using the manufacturer’s figures for the levels of these two substances, the volume that would need to be drunk to reach a lethal dose was modelled. This was calculated by using LD50 figures for alcohol and caffeine. In both Jägerbombs and VKs it was calculated that the alcohol would be at a lethal level prior to the caffeine. 67 Jägerbombs or 53 bottles of VK are required to reach the lethal dose of alcohol in a median human of 65 kg.
