Two men have been arrested after the National Police uncovered a large quantity of nitrous oxide, commonly known as "laughing gas", at a popular bar in the Veronicas nightlife area of Playa Las Americas in south Tenerife.

The operation, carried out with the support of the Arona Local Police, resulted in the seizure of more than 90 large cylinders of nitrous oxide, almost 9,600 balloons, hundreds of gas cartridges and dispensing equipment allegedly used to sell the substance for recreational use.

The bar's manager and an employee have both been arrested on suspicion of offences against public health.

Off-duty officer initiated the investigation

According to police, the operation began during the early hours of 7th June, when an off-duty National Police officer noticed an employee leaving the premises carrying a nitrous oxide cylinder together with equipment used to fill balloons.

The observation prompted officers to inspect the venue, where they discovered a locked storeroom accessible only to staff.

Inside, they found what police described as a distribution centre containing:

• 91 large nitrous oxide cylinders (670 grams each)
• 384 metal gas cartridges
• Two dispensing siphons
• Around 9,600 balloons ready to be filled and sold

Officers also found cylinders, dispensers and used balloons on the pub's terrace, in the toilets and on tables inside the dance area, indicating the substance was allegedly being sold and consumed throughout the venue.

Cash seized during raid

During the search, officers seized €975 in cash from the venue’s manager, consisting mainly of small denomination banknotes that investigators believe may have been linked to the night's sales.

Police said the manager already has previous police records for similar alleged offences.

Meanwhile, Arona Local Police issued administrative reports relating to breaches of regulations governing licensed premises.

Police warn of health risks

Following the operation, the National Police renewed their warning about the increasing recreational use of nitrous oxide among young people, particularly in tourist areas.

Although often viewed as a harmless party drug, police stressed that inhaling nitrous oxide can cause serious health problems, including:

• Oxygen deprivation that can lead to suffocation and permanent neurological damage.
• Sudden dizziness, loss of balance and falls that may result in serious injuries.

The National Police also reminded the public that suspected drug-related offences can be reported anonymously through its dedicated anti-drugs reporting channels.
