The Pozuelo de Alarcón City Council will distribute more than a hundred drug detection cubes during the Friday and Saturday of the Our Lady of Carmen festivities as a pilot test against chemical submission.

Attendees at the Our Lady of Carmen festivities in Pozuelo de Alarcón will be able to collect the so-called drug detection cubes this Friday and Saturday, a system that detects drugs in beverages and turns them into gelatine. The initiative, promoted by the City Council, aims to prevent cases of chemical submission, especially among young people.

A polymer that detects up to five drugs

The cube, developed by the company Narxcup, contains a superabsorbent polymer that reacts to substances such as GHB, liquid ecstasy, burundanga, MDMA, or barbiturates. In a matter of seconds, the liquid transforms into a dense blue gelatine with a bitter taste, making it impossible to ingest. Additionally, the drink changes colour, serving as a visual alert for the victim.

The distribution will take place at the tent set up in the Prados de Torrejón Park, where games and educational activities on alcohol and drug prevention will also be organised. The City Council has acquired more than a hundred of these devices for the two nights of highest attendance.

Pozuelo, "the safest city"

The third deputy mayor and councillor for festivities, Almudena Ruiz, has emphasised that the municipality "is already the safest city in the entire region" and that with this test, they want to continue being so during the festivities. "We are going to test this method, which is as simple as it is effective, to avoid situations that, although very infrequent in Pozuelo, compel us to do everything possible to ensure the maximum safety of our residents," she stated.

That is why we are going to test this method, which is as simple as it is effective, to avoid situations that, although very infrequent in Pozuelo, compel us to do everything possible to ensure the maximum safety of our residents."

The partner and business development director of Narxcup, Santiago Marquina, a resident of Pozuelo, has confirmed that numerous city councils and music festivals have already shown interest in the product. The pilot test will serve to evaluate its effectiveness in a real festive environment.

The initiative is part of a package of security measures that includes violet points for information and assistance, as well as an increase in police presence during the festive days. The City Council encourages young people to approach the tent and participate in the activities, which will take place between 20:00 and 02:00 hours.

For those who cannot attend, Narxcup sells these cubes through its website at a price of about 10 euros each, although distribution at the festivities will be free. The company hopes that if the trial is successful, other municipalities in the Community of Madrid will join the initiative.
