More than 250 deaths linked to drugs were recorded in Northern Ireland during 2024.
Authorities and groups operating drug testing sites state they do not support or promote the use of illegal substances.
Instead, these facilities are described as a method designed to reduce harm among attendees.
Some individuals have suggested that providing such services could create an environment where taking drugs appears more acceptable.
In other parts of the United Kingdom and the Republic of Ireland, dedicated centres exist for rapid analysis of harmful substances found at events.
Belfast City Council has previously requested that testing services be introduced within the region.
However, concerns regarding legal frameworks and available funding have recently emerged again.
Samples collected from searches or amnesty bins are analysed to determine their chemical composition and potency.
When dangerous materials are identified, alerts are issued to festival visitors and medical staff present at the venue.
The process involves sending samples away for laboratory examination before results are returned to the public.
Differences remain in how information regarding these findings is communicated to attendees compared to other jurisdictions.
