Finnish corporal Aimo Koivunen swallowed 90 mg of methamphetamine to stay awake during a 1944 ski patrol in Soviet Lapland. Psychosis followed. He skied 100 km on autopilot, stumbled through a Soviet camp, burned down a cabin, and spent two and a half weeks surviving on pine buds and landmine wounds before rescue. He weighed 43 kg with a 200 bpm heart rate—his toes never recovered. A case study in how war drives armies to chemical desperation.
