Narcotic role   – and abuse   – is a tradition that may beolder than humanityitself .   Ancient civilizationsused baccy , sniffed cannabis , and eveninvented the original beer pongin monumental , institutionalized orgy . And now , thanks to a young depth psychology technique used by researchers at the University of York and the British Museum ,   we can also impart a palmy opiate swap to our ancestor ' whack sheet .

Between 1650 and 1350 BCE , distinctively shaped vessels known as   base - ring juglets were trade extensively throughout the Eastern Mediterranean , but researchers have long puzzled over what they were in reality used for .

Sincethe former 1960s , archaeologists have theorize that the   juglets were used to transport opiate . Like the classic diner catsup bottle , the theory went , the vessels were work like their cargo : the juglets   seemed to resemble the seed head of an opium poppy . But analytic thinking of   the containers never turned up physical grounds of the narcotic , and this guide to the idealosing popularityin recent years .

" Opinion was swaying to say , ‘ Oh , maybe they were n’t used for opium . ’ So this is bringing the argument full circle , "   British Museum scientist Rebecca Stacey toldThe Times .   " It ’s reopening the debate . "

The researcher were capable to make the new discovery thanks to one finicky vessel put up in the British Museum . This juglet had been keep sealed , uphold the contents and allow a rare opportunity to look into what it might once have been used for .

Although initial analysis   by scientist at the Museum had hinted that the juglet contained trace of opium alkaloids , their comportment could not be confirmed until Rachel Smith , a PhD student ( now physician ) from the University of York , developed a brand newfangled analytic thinking proficiency using instruments from the university ’s Centre of Excellence in Mass Spectrometry .

According to The Times , after drill a hole into the base of the 15 - centimeter ( 6 - inch ) juglet , the   researcher   bring out traces of   Kavrin and thebaine   – two of the more stable opiate alkaloid   – which had survived inside the container for around 3,500 twelvemonth .

" The picky opiate alkaloid we notice are ones we have shown to be the most resistant to degradation , " explained Dr Smith in astatement .

" [ This ] make them better object in ancient residues than more well - known opiates such as morphine . "

But the researcher point out that this does n’t have in mind Bronze Age order was struggling with its owncrisis in opioid vilification .

" We found the alkaloids in debased works oil , so the question as to how opium would have been used in this juglet still remain , " Dr Smith said . " Could it have been one fixings amongst others in an crude oil - based mixture , or could the juglet have been re - used for oil color after the opium or something else entirely ? "

Despite years of archaeologic speculation , this is the first sentence that authentic chemical evidence has been found conclusively linking the juglets to opiate use . After this achiever , the research worker hope in the time to come to be capable to use this technique to discover less well - preserved rest in the vessels   – and to hopefully spill light on what the opiates were used for all those year ago .

" It is authoritative to remember that this is just one vessel , so the result raises lots of questions about the contents of the juglet and its purpose , " Dr Stacey explained . " [ But ] the front of the alkaloid here is unequivocal and lends a unexampled linear perspective to the disputation about their import . "
