Nine out of 10 people want to see prisoners tested for drugs while they are in jail, Scottish Tories have said.
An opinion poll for the Conservatives, carried out by YouGov, found 91% of people questioned agreed that inmates should be subject to mandatory drug testing.
The Tories have repeatedly called for action to tackle the drugs problem inside Scotland's jails, including mandatory drug tests. Recent figures showed that drugs were found in prisons 1,705 times between January 1 and November 23.
