We test psychoactive substances, free of charge and anonymously! All information about the offer and registration can be found here.

The Zurich Drug Information Center (DIZ) offers regular drug checkings on site and at parties and festivals.

Drug checking includes a chemical substance analysis for psychoactive, pharmacologically relevant ingredients and a personal consultation. The service is acceptance-oriented, low-threshold, free of charge and is aimed at users of psychoactive substances.

Please note: an appointment must be made in advance for the outpatient drug checking service on our premises. Further information on registration and the procedure can be found in the offer descriptions.

Counseling sessions without substance analyses are also possible by telephone, e-mail or at our premises outside of drug checking opening hours. Further information on our counseling services can be found here.

The DIZ is located at Wasserwerkstrasse 17 in 8006 Zurich (next to the Jugendkulturhaus Dynamo). Since there are no parking spaces in front of the DIZ, we ask visitors to park at the main train station/Sihlquai or at the Marriott Hotel.

Minors are also allowed to submit a substance for analysis and to make use of the counseling service. However, the DIZ is not a place for small children. If there is no supervision during the DIZ appointment, no substance can be delivered. In addition, as this is a medical facility, dogs cannot be brought into the DIZ. There is also no possibility to tether dogs in front of the facility.

When and how will I receive my result?

The result can be viewed on Friday of the following week between 14:00 and 17:00. online or by calling +41 44 415 76 46 can be queried.

What can be analysed?

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.

How it works

Cannabis flowers:
If small amounts are still present (at least 0.2 grams) and synthetic cannabinoids are suspected, qualitative analysis for extenders is possible, but no quantification of THC/CBD.

For quantification of THC/CBD content, grind/grind 2-3 grams of the flower and submit 1 gram for analysis. Stems should also be included (for a realistic content determination as well as for the detection of possible synthetic cannabinoids). The samples must be dry, otherwise a realistic content determination is not possible and there is a risk of the sample becoming moldy.

Hash:
If small amounts are still present (at least 0.2 grams) and synthetic cannabinoids are suspected, a qualitative analysis for extenders is possible, but no quantification of THC/CBD.

For a quantification of the THC/CBD content, grind/grind 0.5 grams (if this is possible from the consistency). With smaller sample quantities, optimal analysis becomes difficult.

Oil/Dab/Liquid:
Varies, smaller quantities are generally required for highly concentrated samples.

What do we offer?

Chemsex Drug Checking provides information about the effects and dangers of psychoactive substances consumed before or during sex and about the risks of one's own consumption behaviour. The counselling enables precise information about dosage and ingredients as well as about the effects that these ingredients can have on the user. With us, sex on drugs can be discussed in a moral and value-free way.

The service is anonymous and free of charge. The chemsex counsellors know the queer sex world and the topic of sexualised substance use. There is a mandatory counselling interview with every person who hands in a substance for analysis. There are no preconditions for a visit to Chemsex Drug Checking and the staff are bound by professional secrecy.

You are also welcome to ask us for information and advice

  • Do you have questions about chemsex substances, their mechanisms of action, consumption experiences, trends or the effects on your health?
  • Are you interested in safer use of typical chemsex substances?
  • Do you want to stabilise your consumption, reduce it or give it up completely?
  • Questions about the offer, further advice etc. can be sent to us at any time by e-mail (chemsex@zuerich.ch) or telephone: 044 455 59 10.
