Cannabis legalization in Germany: Changed liability in cannabis law and turning points for drivers

Discussion about cannabis and cannabis use: legalization in Germany and effects on car control regarding THC levels

The legalization of cannabis in Germany is a controversial topic with far-reaching consequences. The focus here is on the issue of road safety, particularly with regard to THC controls in road traffic. Uncertainties about the permitted amount of cannabis consumption and the associated THC amount also play a decisive role.

Background to cannabis legalization in Germany

The legalization of cannabis could bring economic and social benefits in Germany. From increased tax revenues to medical applications, there are many potential effects. But the question remains as to how the state would handle the amount of cannabis use and THC car control.

The role of THC in road safety

THC control in road traffic is one of the biggest challenges in the legalization of cannabis. Drivers who are under the influence of cannabis could endanger road safety. Therefore, precise guidelines for THC testing and appropriate penalties for violations must be developed. The Federal Cabinet has decided that from July 2025, adults will be allowed to possess 25 grams of cannabis and grow up to 3 cannabis plants. The yield of the plants is not commercial and is intended for personal use.

The debate about THC limits on THC car control

The discussion about THC limits is a key issue. The current limit is 1.0 nanogram (ng) of tetrahydrocannabinol (THC) per milliliter of blood serum. The current limit value is so low that it can only prove whether cannabis consumption is present, but not whether it is relevant to road safety. In addition, according to § 24a StVG, a fine of at least 500 euros, a driving ban, points in Flensburg and, in the worst case, revocation of the driver’s license can be expected if this value is exceeded.

A step towards changing THC car control

An increase in the THC limit value to 3.5 nanograms per milliliter of blood serum is being called for by the chairman of the limit value commission, Prof. Stefan Tönnes. This is to ensure that people who are fit to drive again after consuming cannabis are not wrongly punished. In order to find a suitable limit value that better reflects actual driving ability, there are plans to set up a team of experts comprising doctors, lawyers and traffic experts at the Ministry of Transport.

Outlook on the future of cannabis legalization in Germany

The Ministry of Transport does not want to make a forecast: “In the context of § 24a para. 2 StVG, the only thing that matters according to previous case law is whether there was a possibility of impaired fitness to drive,” says the ministry.

Questions and answers about the Postbank hacker attack:

  • How would the legalization of cannabis in Germany affect THC car control?

    The legalization of cannabis in Germany would require an adjustment of the THC car control. Drivers can be impaired by cannabis use, which places new demands on road safety. Germany would therefore have to draw up precise guidelines for the amount of THC to be tolerated and penalties.

  • What impact does the current THC limit of 1.0 nanogram per milliliter of blood serum have on road users in Germany?

    The current THC limit of 1.0 nanogram per milliliter of blood serum has a significant impact on road users in Germany. If this limit is exceeded, there is a risk of fines, driving bans, points in Flensburg and, in the worst case, revocation of the driver’s license, even if there is no acute impairment of driving ability.

  • What measures are being taken to develop an appropriate regulation of THC limits in the context of the legalization of cannabis use in Germany and road safety?

    In order to develop an appropriate regulation of the THC limit values, a team of experts consisting of doctors, lawyers and traffic experts will be formed within the Ministry of Transport. This team should ensure that the limits better reflect actual driving ability and that people who are fit to drive again after using cannabis are not unfairly penalized. This is a step towards fairer regulation of THC limits in Germany.
