Your memories may be false if you try to remember events you witnessed while you were high on marijuana, a new study suggests.
He discovered that taking just one stroke of the drug doubled the number of false memories of a virtual reality scenario, CNN reported.
A false memory is one that didn't really happen or that differs from the way an event happened, often influenced by other people's suggestions.
"We are all prone to the formation of false memories, regardless of cannabis use," said study author Johannes Ramaekers, professor of psychopharmacology at the University of Maastricht, The Netherlands, CNN reported.
"However, susceptibility to false memory increases with cannabis. Under cannabis, users can easily accept false truths for true memory," Ramaekers said.
With the increase in the legalization of marijuana in the United States, the increase resulting from false memories could affect people's family, work and social life, as well as criminal investigations, CNN reported.
