In September, a record seizure of around 30 tonnes of gas had been carried out during the inspection of a truck at a toll booth in Montauban, followed by a search in the Gers. This new interception on the A89 is part of a series of roadside checks targeting nitrous oxide cargoes.
Used notably in cooking or in medicine, nitrous oxide has seen its use diverted in recent years because of its short psychoactive effects after inhalation, despite serious health risks.
The Tulle prosecutor's office has not provided further details on the origin of the merchandise or on any possible recipients.
Health authorities recall the dangers associated with the diverted inhalation of this gas, particularly for the youngest.
The investigations opened after the inspection of the heavy goods vehicle are continuing in order to establish the circuit of this cargo.
The driver, aged 28, whose nationality has not been specified, was placed in police custody then released. The investigations are continuing, the prosecutor's office said.
Under the Ripost law, the sale of this gas will be banned and its inhalation punishable by one year in prison from February 1, 2027.
According to Santé publique France, 10% of the 800 reports linked to nitrous oxide consumption in 2023 concerned minors.
