Now you have to decide to stop your alcohol and / or drug use in order to prove your abstinence.

For medically prescribed drugs, the active ingredients or metabolites of which are subject to the regulations of the CTU3 criteria, a doctor's certificate must be submitted before the urine sample is examined, which proves the mandatory prescription of these drugs. Otherwise, an arbitrary intake of this substance (s) can be assumed. The program must then canceled become.

Alcohol abstinence:

In addition to abstaining from alcoholic beverages, foods containing alcohol such as B. Tiramisu, wine sauce, confectionery (pralines, etc.) should be avoided. Mouthwash containing alcohol and over-the-counter herbal medicinal products based on alcohol (e.g. Iberogast®, Echinacin drops) must not be taken, as they always lead to the detection of ETG in the urine. Please note that so-called "non-alcoholic beer (including sparkling wine / wine)" and naturally cloudy juices (e.g. apple juice) can contain small amounts of alcohol.

Drug screening:

Food containing poppy seeds (poppy seed cakes, poppy seed rolls, poppy seed yoghurt) must be avoided as they always give a positive opiate test result. Consuming hemp products and staying in rooms with cannabis smoke in the ambient air can produce a positive cannabis test result in the urine. Unknowingly ingesting narcotics cannot be taken into account.

As of May 1st, 2014, positive analytical results below the limits of quantification required in the chemical-toxicological examination must be reported on the analytical report and assessed as proof of consumption (assessment criteria for fitness to drive, 3rd edition). Therefore, adapt your behavior accordingly as a precaution!

Urine dilution:

The degree of dilution of the urine is determined by the creatinine concentration. We would like to point out that if the urine is diluted, i.e. creatinine concentration below 0.2 g / l (e.g. due to excessive fluid intake), the result of the toxicological urine screening by your MPU or driver's license office Not is recognized. In your own interest, we therefore recommend that you do this before giving urine never large amounts of liquid (e.g. coffee or tea) to drink. If a urine sample is submitted that has a creatinine value below 0.2 g / l twice in a row, the program must be terminated, as the findings will then no longer be recognized by the MPU office. Conditions and illnesses that are medically certified as an acceptable medical explanation are an exception.
