German law stated that a driver’s licence could be revoked if they could not drive due to the consumption of alcohol or other drugs, and those caught with one nanogram per millimetre of THC in their bloodstream faced the instant loss of their licence.
A group of experts proposed in 2015 to increase the limit to three nanograms per millimetre because THC can remain in the bloodstream days after a person consumes cannabis.
But on Tuesday the Leipzig Federal Administrative Court ruled the limit should stay the same.
Last year, a police officers’ organisation in Germany called for the decriminalisation of the consumption of cannabis.
Andre Schulz, head of the BDK organisation (the Association of German Criminal Officers), said the group favours a “complete decriminalisation of cannabis consumers”.
He said the current system prohibiting marijuana use stigmatises people and “allows criminal careers to start”, and argued “the prohibition of cannabis was, viewed historically, arbitrary” and is “neither intelligent nor expedient”.
“In the history of mankind there has never been a society without the use of drugs,” he said. “This is something that has to be accepted. My prediction is cannabis will not be banned for long in Germany.”
However, he insisted the drug should remain off-limits for drivers.
