As well as detailing the service’s activities during the year, it also reveals the top ten drugs seized by its officers.

1. CANNABIS

The class B drug cannabis was the most-seized drug in 2016, with Customs confiscating £2.7 million worth of the substance.

2. ECSTASY

A total of £856,075 worth of the pills was seized last year. The drug hit the headlines recently when a Jersey teenager died after taking tablets from a particularly strong batch.

3. SUBUTEX

The heroin substitute Subutex was the third most seized drug, with £59,420 worth of the substance confiscated.

4. NEW PSYCHO-ACTIVE SUBSTANCES

NPS – or legal highs as they were once known – exploded onto the drugs scene in 2008. Their use seemingly peaked a few years ago, but Customs are still catching people with the illegal substances. A total of £55,093 worth of the drugs were seized in 2016.

5. HEROIN

The use of the class A drug heroin dropped a few years ago after an opium crop failure in Afghanistan led to a huge rise in prices. Users also began turning to NPS, which were arriving in Jersey in greater numbers. But £50,620 worth of the drug was still seized last year.

6. STEROIDS

A total of £9,980 worth of the body-building drug was seized by Customs in 2016.

7. DIAZEPAM

Customs confiscated £7,725 of the drug last year.

8. OTHERS

A number of less familiar controlled drugs were seized in much smaller quantities during the year. A total of £7,585 was seized.

9. COCAINE

Party drug cocaine accounted for £2,183 worth of the total amount of drugs seized by Customs officers.

10. AMPHETAMINE

The least-seized drug was amphetamine, with £1,500 worth being confiscated.
