New cannabis law and cycling: A new cannabis law came into force in Germany from April 1st. Possession and consumption are permitted under certain conditions. But compared to alcohol, cannabis is different and can be detected for longer, which also fuels the discussion about the limits for a traffic stop. We asked ourselves what this means for the topic of cycling and cannabis.
Cannabis is the most commonly consumed substance worldwide. It is also very popular in Germany, although it is controversial. The debate about possible legalization has lasted for years. The traffic light government has already agreed on this in the coalition agreement, and the consumption of cannabis has been partially legalized since April 1, 2024. Possession and cultivation are now permitted under certain conditions, but driving under the influence of cannabis remains prohibited. There are currently no exceptions for cyclists due to the new cannabis law.
Cannabis law: Can I ride a bike while stoned?
In a recent press release, the German Traffic Watch warns against underestimating the effects of cannabis on the ability to drive. People who have consumed cannabis are temporarily unable to drive. The effects of cannabis on the ability to drive are varied and complex, including fatigue, impaired perception and concentration, and impairment of the ability to react and think.
The traffic watchdog therefore advocates comprehensive information about the effects of the legal drug. Professor Kurt Bodewig, President of the German Traffic Watch, emphasizes the need for a clear separation between drug use and active participation in road traffic in order to reduce the risk of accidents. He states: “Anyone who is under the influence of cannabis should not be behind the wheel.” Regarding the limit values, the traffic watchdog recommends maintaining the current limit of 1 nanogram of THC per milliliter of blood serum for novice drivers.
Discussion about limit values not yet concluded
The discussion about the limits for novice drivers and other road users is not yet complete. A working group made up of experts from various fields has suggested setting the limit at 3,5 nanograms of THC per milliliter of blood serum. This value is considered conservative and is said to be comparable to a blood alcohol level of 0,2 per mille. However, the final decision on this limit is still pending.
Until the Road Traffic Act is changed, the absolute ban on driving a bicycle or car under the influence of cannabis continues to apply. Driving under the influence of cannabis is not only a misdemeanor, but can also be punished under criminal law, especially if it leads to a specific dangerous situation. An exception to the sanctions applies to people who have been prescribed cannabis as a medication, for example to treat chronic pain.
The discussion about the limit value for THC content in the blood is still ongoing. Previously, the limit was 1,0 nanograms of THC per milliliter of blood. However, the German Traffic Court had already recommended increasing this limit in 2022 because it was considered too low. The topic is complex because, unlike alcohol, THC does not break down linearly and can still be detectable after weeks, even though the effect has long since worn off. So exactly what happens next with the issue of the new cannabis law and cycling remains to be seen.
