New drugs are coming on the market every week in Northern Ireland - and experts charged with analysing them are struggling to cope with the influx.
The warning comes from a senior official at Forensic Science NI, the organisation at the front line of investigating the deadly trade.
In the last year 81 new types of drugs appeared across Europe, with most of them finding their way to Northern Ireland – that's an average of one new drug emerging every five days.
The dangers of these substances have been highlighted in a series of recent inquests. One stimulant, Para-methyl-4-methylaminorex – known more commonly as 4,4-DMAR – has been linked to 21 deaths across Northern Ireland.
According to Peter Barker, director of reporting services at Forensic Science NI, experts are struggling to keep up with the rapidly changing drugs scene.
