James Wightman, 67, of Den Walk in Methil, Fife, was stopped on the M74 northbound near Moffat in July last year.
The Ford Transit van he was driving was found to contain a large amount of the class A drug, with an estimated street value of nearly £99,000.
He had previously pled guilty at Dumfries Sheriff Court to being concerned in the supply of drugs. On Tuesday, he was sentenced to 21 months imprisonment, reduced to 14 months for an early plea.
Wightman was caught as part of an investigation led by the Organised Crime Partnership (Scotland), made up of officers from Police Scotland and the National Crime Agency.Intelligence about Wightman's activities had been obtained during Operation Venetic – a UK-wide operation aimed at targeting organised and serious crime. It culminated in the taking down of an encrypted communications service used by criminals.Detective Inspector Tom Gillan, of the Organised Crime Partnership (Scotland) said: “This conviction and sentencing serves as yet another example of our ongoing commitment to target the supply and distribution of controlled drugs across Scotland, which remains an absolute priority for the Organised Crime Partnership and its partners.“I would like to take this opportunity to remind the public that information from our local communities is an essential part of our investigation process, as we work to disrupt the drugs trade and bring those responsible to justice.”Rob Miles, National Crime Agency Operations Manager, said: “Preventing organised crime groups from profiting from the supply of class A drugs into Scotland is a major priority for the OCP and the NCA.“Working with our partners at Police Scotland we are determined to do all we can to disrupt and dismantle those supply networks.”
