Scientists have warned about the risk of drug contamination in used cars.

When purchasing a used car, buyers often struggle to uncover its complete history. Research conducted by Australian scientists has revealed that if a vehicle has previously been used to consume or transport methamphetamine, it may lead to potentially hazardous residual contamination of surfaces and air within the cabin.

Traces of methamphetamine, the circulation and use of which is prohibited in Russia, can easily spread within a vehicle. Subsequently, tertiary exposure to the drug can lead to headaches, breathing problems, and changes in cognitive functions and behavior.

However, there is insufficient scientific data regarding such contamination in passenger vehicles. Environmental hygiene specialists from Flinders University have taken on this issue. Their article was recently published in the journal Forensic Chemistry.

Through a series of tests, the researchers assessed the level of methamphetamine contamination on various surfaces and in the air of two vehicles—a Holden Cruze sedan and a Subaru XV crossover. Details of their findings are not provided in the article, but it is noted that evidence of involvement in illegal drug trafficking and methamphetamine use had previously been discovered in the vehicles: smoking pipes, over two hundred syringes, and other items.

Swabs were taken from the dashboards, air vents, and door surfaces on both the driver and passenger sides. Additionally, air samples were collected: in one vehicle—from the trunk and the area near the front passenger seat, and in the other—from the back seat. In the vehicle that was later planned for disposal, material samples were taken from the seats, headrests, and floor coverings.

As a result, methamphetamine was found in 85% of swabs taken from both non-porous and porous surfaces, and in 93% of the material samples collected from the cabin. Traces of the substance were even detected in the third and fourth swabs from the plastic surfaces of the vehicles. It was also identified in all air samples taken from the vehicles.

According to the researchers, the findings highlight the issue of potential hidden drug contamination in used cars. Unaware of this, new owners may jeopardize their health and that of their passengers.

Australian specialists continue to investigate this area. In a new series of tests conducted under controlled laboratory conditions, they aim to more precisely determine the level of residual contamination caused by smoking methamphetamine in a car's interior. The researchers believe that the results should prompt stricter regulations on the sale of used vehicles and more thorough inspections of their condition.
