Abigail Kavanagh delivered the synthetic cannabis to jails across Wales while working as a "pivotal" member of an organised crime group.
Detective Constable Rhys Richards, of Tarian, said: “Abigail Kavanagh was a pivotal member of an organised crime group.
The court previously heard how Kavanagh disguised MDMA as bath salts in a bid to smuggle the Class A drug into Britain.
A WOMAN who raked in £88,000 helping flood UK jails with zombie drug spice has been ordered to pay back just £1 after blowing the lot.
Kavanagh was arrested under Operation Gemstone, which is run by the Regional Organised Crime Unit for South Wales.
