Discovery of two gold bongs is evidence that Aryan kings used to smoke cannabis at ceremonies. These artifacts are 2,400-year-old.
The historic drug paraphernalia was found alongside 7lbs of other gold items when an area of land was dug up in Russia to make way for power lines.
These items had been buried in a stone chamber before being concealed by a thick layer of clay.
Criminologists have since carried out tests which indicate that the thick, black residue found inside the vessels comes from the cannabis and opium which the tribal royal smoked.
Experts believe the items belonged to the Scythians, a nomadic warrior race who ruled large swathes of Europe and Asia between the 9th century BC and the 4th century AD.
It means the so-called bongs could be some of the oldest in existence.
Several historians say the Scythians smoked, and sometimes brewed, a strong concoction of cannabis and opium in order to alter their state of mind before heading into battle.
Famed Greek historian Herodotus, who died in 425BC, wrote: ‘Scythians used a plant to produce smoke that no Grecian vapour-bath can surpass which made them shout aloud.’
The dig also led to the discovery of golden cups, rings, and neck rings. All the items have since been cleaned and put on display in a Russian museum.
Antonn Gass, from the Prussian Cultural Heritage Foundation, in Berlin said: ‘These are among the finest objects we know from the region.’
