|A cannabis drought in Ulster has forced dealers and users to make trips to Scotland for their drugs.|
A spokesman for Strathclyde Police said it had received information more people from the province were travelling to Glasgow to buy supplies.
It's understood a number of police raids in recent weeks and a clampdown by loyalist paramilitaries has hit cannabis supplies.
With prices rising as a consequence, the 'drug runners' are risking prison by making the regular trips.
Said the spokesman: "We have had reports that more people from Northern Ireland have been travelling to Scotland to purchase drugs.
"If these people are caught purchasing any type of illegal drugs off dealers in Glasgow, then they will face the full rigours of the law."
The spokesman said Glasgow had a "serious drug problem" and links between criminal gangs in the city and Belfast were well-documented.
"We will continue to work closely with the PSNI if they require our help on the illegal drugs trade between the two regions," he added.
Belfast councillor Jim Rodgers welcomed the fact there seemed to be a cannabis drought.
He said: "The police have been very successful in recent weeks against drug dealers and I hope this trend continues.
"I also know that loyalist paramilitaries are trying to clean up their act and maybe this is why it has been a lot harder for people to buy this drug."
Said a PSNI spokeswoman: "We work closely with various police forces in the UK in the war against drugs. Our efforts to reduce drugs will continue and these efforts will focus on those responsible for importation and distribution."
