Dagnis Karklins admitted counts of importing the class A substance and possessing it at his home.
The court heard how the defendant had arrived in Guernsey on a flight from Exeter in November last year.
He told Customs officers that he was travelling alone and had been to Devon to visit friends. He was carrying a bag that contained £800 in cash, a bottle of spirits and a bag of tobacco.
He said he had won the money at a casino. Cash in his wallet took the total amount he was carrying to £1,351.
Karklins said he was not carrying any drugs and when told that an ion scan test of his belongings would be carried out to test for the presence of drugs, he then said that he was prescribed cannabis.
When the test proved positive for cocaine, he admitted using that drug and said he had been ‘a naughty boy’.
He was reluctant to allow customs officers to perform a strip search effectively and was transferred to hospital where an internally-concealed package was discovered via a CT scan.
The drug concealed internally weighed 55.32g and had a local street value of up to £8,298.
A further 3.47g was found, along with a further £700 in cash, when a drug search warrant was executed at his home.
His mobile phone was seized and a small number of messages recovered were relevant to controlled drugs.
A Latvian national, Karklins was not registered locally with Population & Immigration. He had worked in Guernsey for five years, most recently as a stonemason.
Defending, Advocate Sam Maindonald said her client was a hard worker who had been contributing to the local economy by paying tax and insurance. The drugs were intended for his personal use.
A letter submitted set out his addiction and history of drug-taking along with his apology and remorse.
He had been working to support a sick parent at home and these offences had been to his shame.
Judge Catherine Fooks said the defendant had imported a significant quantity of cocaine.
Under the court’s sentencing guidelines, the quantity involved precluded any suggestion that personal use of the drugs was a mitigating factor.
The method of importation was the most unpleasant and resource intensive that Customs officers had to deal with. Karklins’ best mitigation was that he had no previous convictions.
Karklins was jailed for six years for the importation with one month, concurrent, for the possession offence. Forfeiture and destruction of the drug and its packing was ordered.
The court acceded to the prosecution application and will recommend to the Lt-Governor that the defendant should be deported when he has served his sentenced.
A drug trafficking investigation will also take place.
