The DIZ Zurich offers cannabis drug checking every Wednesday, where cannabis products can be tested for purity and impurities. The service is free and anonymous.
Drug Checking is located at Wasserwerkstrasse 17 in 8006 Zurich (next to the Jugendkulturhaus Dynamo). There are no parking spaces available on site.
Wednesday from 16.30 to 18:30
An appointment must be made in advance in order to hand in the substance. Appointments can be booked online from 16:00 the day before at the earliest. Click on Make an appointment above.

The following substances can be analyzed quantitatively (to determine how much is present):
List of Substances: Wasserwerkstrasse, Cannabis
Whatcan be analyzed?
Flower, hash, pollinate, extracts (such as oils, dab, dick extracts, e-liquids) and pure substances (such as pure CBD). Samples intended for medical use (e.g. oils containing CBD) are also accepted.
Cosmetics and "regular" food (tea, sweets, hemp beer, etc.) from the specialized trade are excluded. Exceptional cases, such as space cookies, where synthetic cannabinoids are suspected, can be analyzed qualitatively.
Cannabis flowers:
If synthetic cannabinoids are suspected, a qualitative analysis for cutting agents can be performed even with small sample sizes.
To quantify the THC/CBD content, grind 2–3 grams of the flower and submit 0.25 grams of it for analysis. The sample should also contain stems (to ensure a realistic determination of the content and to detect any synthetic cannabinoids). The samples must be dry; otherwise, an accurate determination of the content is not possible, and there is a risk that the sample will develop mold.
Hash:
If synthetic cannabinoids are suspected, a qualitative analysis for cutting agents is possible even with small sample sizes.
To quantify the THC/CBD content, grind 0.25 grams (if the consistency allows). Optimal analysis is difficult with smaller sample sizes.
Oil/Dab/Liquid:
Different, smaller quantities are generally required for highly concentrated samples.
The test results will be available online on Friday of the same week starting at 2:00 p.m. online, in person at our office, or by phone at +41 44 415 76 40 (between 2:00 p.m. and 5:00 p.m.). You’ll need the sample reference number and the password you agreed upon when you dropped off the sample. If you no longer have this information, please call the number listed above.
