Gino Antonio Pallisco, 35, admitted importing 222.38g of cocaine and 100.2g of ketamine.
He was sentenced nine years and eight months for the cocaine offence and three years for the ketamine offence, which will be served concurrently.
‘You are of moderate risk of reoffending, and this cannot be tolerated,’ said Judge Catherine Fooks.
‘You admitted that you were only thinking about yourself and you could have caused an unspeakable impact on the community.’
Pallisco had previous convictions in Wales, but none were drug-related and none since 2017.
He had been remanded in custody locally since November.
Pallisco came back to Guernsey, where he was living and working, after visiting family in Wales.
He came off of a ferry in a white Mercedes and went through Customs checks, when he confirmed he understood what he was not allowed to bring into the island. He denied having controlled drugs.
He said that it was his own vehicle which he had packed himself and he was not carrying anything for anyone else.
His phone, hat and backpack were swabbed and tested positive for traces of cocaine.
He then admitted he was a recreational user and had done so the weekend before.
In a search of the car, officers found a packet of Bold washing detergent tablets.
An X-ray showed inconsistencies, and a clear ziplock bag was found inside containing a white powder, which was later identified as ketamine.
Officers also found a Tesco carrier bag, which had boxes of Capri Sun drink pouches. The boxes were sealed and unopened.
There were four individual pouches in each box, but one did not feel the same as the others containing liquid.
It was opened and white powder was found inside, which was later discovered to be cocaine.
Two further drinks pouches also contained cocaine, totalling 222.38g.
A receipt found in the carrier bag confirmed the purchases of the drinks, along with super glue.
Pallisco’s home address was searched and rubber bands consistent with the ones used in packaging the drugs were discovered.
Defending, Advocate Samuel Steel said that his client had longstanding drug debts in the UK and was fearful for the safety of his family.
He had a long history of drug misuse, abstinence and relapses.
He admitted that he had only been thinking of himself.
Pallisco’s phone had been searched and there was nothing to suggest that he was involved in drug trafficking.
Advocate Steel said his client had been held on remand in custody since November, and was desperate to be sentenced and transferred back to the UK to be closer to his family.
His phone and the drugs seized will be forfeited.
