It represents a substantial increase on 2018.
Over €2.2m of drugs was seized in Portlaoise Mail Centre in 2019, by far the largest figure in Ireland.
According to freedom of information files, nearly four times as many drugs were seized in Ireland's mail centres last year as in 2018.
Including €91,000 of drugs discovered at the mail centre in Athlone.
In 2018, 2.6 million euro of seizures were made by Revenue - but this rose to over 9.7 million last year.
Mullingar Security analyst Declan Power believes there's a number of reasons for the sharp rise in the amount of drugs being posted:
