Cannabis Used to Grow Wild in Europe but Went Extinct Before First Farmers Arrived, Research Finds


Scientists now believe plant was commonplace on continent in prehistoric period.

The growth of wild cannabis was rife in Europe during the Stone Age, but the plant disappeared from the continent before the first farmers had a chance to cultivate it, according to new research.

Scientists have previously struggled to determine where the plant grew, as its similarity to the related common hop meant usual methods of studying pollen fossils had proved difficult.

However, a group of researchers from the University of Vermont led by John McPartland now believe they may have solved the mystery, by examining what else was growing in the area.
