    Wake me up when they also update the traffic laws. Positive drug test because you smoked a week ago? There goes your drivers licence.

      German traffic laws are not my area of expertise, but can you also lose your license if you drank alcohol a week ago?

      It’s not entirely a 1-to-1 comparison, but weed doesn’t have That long an impact on reaction times.

        The alcohol test is carried out using a breathalyser and, if positive, is confirmed by a blood sample. This works well because it measures the concentration of alcohol still in your blood. A positive test means that the driver is (still) drunk and not fit to drive.

        The test method for THC is not as accurate. A urine sample can still be positive 3(!) days after smoking a joint. This is even worse with hair samples or if the person smokes occasionally.

        Limiting testing to THC alone would be a sensible decision. At the moment they also test for THC-COOH, which is a metabolic by-product and lasts much longer in the body.

        Without a change in testing methodology, you could lose your driving licence on Monday because you smoked a single joint on Friday. A bottle of vodka on Saturday? No problemo.

          Interesting, thanks for the explanation. I’d been looking forward to it being legal here but not if it means I risk this. I guess it will be a few times a year treat if I’m spending a week off work at home just chilling out.
