Would-be traders will be dealt with
Prisoners who try and use e-cigarettes as currency risk being segregated, as a trial into their use continues.
Isle of Man Prison's governor, Bob McColm, says staff are taking a strict approach to those breaking the rules.
A test period for e-cigs is currently well underway at the Jurby site.
Each of the devices has a unique index number, so those behind bars can't trade the vape devices.
Bob McColm insists anyone caught breaching the rules is being punished:
