Ukrainian soldiers have speculated that Russian troops are fighting while high on amphetamines.
Nazi troops were given methamphetamines during World War II to decrease fear and increase aggression.
Germany even organized a rehab program for "overflown" pilots, or those who were addicted to the drug, Ohler said.
The Russian military gave its soldiers vodka rations to get through World War II; France opted for red wine; and alcohol remained the "number one" drug for Germans during the war, Ohler said.
"I would be surprised if drugs were not being used in the Ukrainian-Russian war," Ohler said.
