Drug Checking
Filter
The DIZ is located at Wasserwerkstrasse 17, 8006 Zurich (next to Jugendkulturhaus Dynamo).
Every substance delivery is associated with an obligatory counselling interview. Anonymised data on age, gender and consumption patterns are collected.
As this is a medical facility, dogs cannot be taken into the DIZ. There is also no possibility to tether dogs in front of the facility.
We ask that you arrive punctually at the agreed time. Otherwise, the sample can no longer be accepted for analysis.
The following substances can be analysed quantitatively and qualitatively:
For the analysis, a whole tablet, a whole felt, two knife tips (30-50mg) of a powder or 1 g of plant material are required. Those wishing to have amphetamine pastes tested should dry them beforehand. LSD on sugar cannot be accepted. The sample material provided will be used entirely for laboratory analysis and will not be returned.
The results are usually given quantitatively as hydrochloride (HCL, salt form of the substance), for LSD in tartrate and for DMT as base. The values vary to the same substances as base or sulfate. At drogenkult.net under "Dosage" hints for the conversion of the individual substances are available. A small summary on the subject of conversion can be found here on our site.
A large number of other substances can be analyzed at least qualitatively. For questions just send an email to info@saferparty.ch contact
Counselling sessions are also possible outside opening hours by appointment by phone or email.
For legal reasons we are not allowed to accept samples sent by post!

When I use cannabis products as self-medication to treat pain, to promote sleep, etc.
If I am fundamentally suspicious about what exactly the acquired cannabis product is
When and how will I receive my result?
The result can be requested on Friday of the following week (after 8 days). You have to call the following number between 3 p.m. and 6 p.m.: 044 415 76 46.
The following cannabis products (matrices) are basically accepted:
Flower, hash, pollinate, extracts (such as oils, thick extracts, e-liquids) and pure substances (such as pure CBD).
Samples intended for medicinal use (e.g. CBD-containing oils) are also accepted.
Cosmetics and "regular" food (tea, sweets, hemp beer etc.) from specialised shops are excluded. Exceptional cases, such as space cookies, where synthetic cannabinoids are suspected, can be analysed qualitatively.
Sample quantity/ sample preparation:
Cannabis flowers:
Grind 2-3 grams and submit at least 1 gram for analysis. It should also contain stems (for a realistic content determination and for the detection of possible synthetic cannabinoids).
In the case of smaller amounts still present (at least 0.2 grams) and a suspicion of synthetic cannabinoids, a qualitative analysis is possible, but no quantification (determination of the content) of THC/CBD.
The samples must be dry (as they are smoked). Otherwise, a realistic determination of the content is not possible and there is a risk that the sample will become mouldy.
Hash:
Grind 0.5 to 1.0 gram (if this is possible in terms of consistency). With smaller sample quantities, optimal analysis becomes difficult.
Oil:
1.0 gram. With smaller sample quantities, optimal analysis becomes difficult.

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
