27.01.2026 – Study on driving and THC

studiefahren26.jpgZero tolerance for THC in road traffic has been in force for 20 years. As soon as THC is detected in the blood, a person is considered unfit to drive, even if no impairment is apparent. It hardly seems possible to establish a meaningful effect limit for THC in the blood. This new study now aims to find out whether the actual, real impairment can be measured or how it can be determined that the ability to drive is given. You can find more information in this flyer.
