Hiroshima Effect Refers to the sudden rush or onset of a state of intoxication that occurs after the user enters a warm climate after consuming Marijuana out in the cold. Usually associated with the consumption of Marijuana or Marijuana derivative. Unknown origin, but assumed to be coined in Ontario, Canada around 1988. It draws on the idea that a sudden rush or onset of extreme intoxication (really high) is like being hit by an atomic bomb.
