The tonic wine Buckfast has been mentioned in 5,000 crime reports by Scotland's biggest police force in the last three years, an investigation revealed today.
Almost one in ten of those crimes in the Strathclyde Police area was violent, according to figures obtained by the BBC under Freedom of Information legislation.
Buckfast bottles were used as a weapon 114 times during that period.
Police said the figures suggested there is an association between Buckfast and violence.
The findings are revealed in the programme BBC Scotland Investigates: The Buckfast Code to be broadcast tonight.
During the programme Superintendent Bob Hamilton of Strathclyde Police was asked whether the figures mean that Buckfast can be said to be associated with violence.
He replied: 'I think it's clear from the figures that there is an association there.'
Buckfast is produced by monks in a Devon monastery.
The investigation looks at the ingredients of the drink and how they may affect the behaviour of consumers, potentially making them anxious and aggressive if drunk in large quantities.
Neuroscientist Dr Steven Alexander tells the programme there is 281mg of caffeine in a bottle of Buckfast, which is as much caffeine as in eight cans of coke.
Asked about the effects of consuming more caffeine than there is in 16 cans of coke, Dr Alexander said: 'It's going to have [them]bouncing around all over the place because the anxiety levels, the adrenalin will be running around.
'[They] will certainly be feeling very anxious, very aggressive.'
The programme reports that around the world there is increasing concern about the effect of caffeine when mixed with alcohol, with the US Food and Drug Administration considering banning pre-mixed caffeinated alcohol drinks altogether.
The BBC said a request for an interview with the monks of Buckfast Abbey to respond to the issues raised was turned down.
Scottish Justice Secretary Kenny MacAskill said Buckfast was not the only problem affecting the country.
He told BBC Radio's Good Morning Scotland programme: 'We're concerned at the effect all drinks are having in Scotland because it's costing us a fortune, it's overburdening our health service and it's undermining our economy and society.'
