Chemsex Drug Checking

On the first Monday of every month, you can have your chemsex substances tested free of charge and anonymously at Checkpoint. A cooperation offer by Saferparty of the City of Zurich and us.

Chemsex Drug Testing in June has been postponed to 13 June.

How’s it going?


Book by phone

You register anonymously by phone (see below).


On site

Please check in at the reception desk on the first floor at the agreed time. You will then receive a waiting number and will also be called with this number. Your anonymity is guaranteed, no one in the waiting room will be able to tell that you are coming for chemsex drug testing.



You have a counselling session with a professional who specialises in chemsex. The interview is documented by means of an anonymous questionnaire.



Your samples are tested qualitatively and quantitatively in a certified laboratory. For the analysis, a whole tablet, a whole felt or two knife tips (30-50mg) of a powder are needed. If you want to have amphetamine paste tested, we would like to ask you to dry it first. Only one substance per person can be submitted for analysis.



You will be informed of the results of the analysis by telephone. If you have something tested on Monday, you will have the result the following Friday shortly before the weekend. Results can be requested by telephone from Friday, 16.00.

What do we offer?

At Chemsex Drug Checking at Checkpoint Zurich, you will be informed about the effects and dangers of psychoactive substances that you consume before or during sex and about the risks of your own consumption behaviour. Counselling allows for accurate information about dosage and ingredients, as well as the effects these ingredients can have on you as a consumer. You can talk to us about sex on drugs in a moral and value-free way.

These substances can be analysed quantitatively and qualitatively (PDF)

The offer is anonymous and free of charge. The chemsex counsellors know the queer sex world and the topic of sexualised substance use. A mandatory counselling interview is conducted with each person who submits a substance for analysis. The visit to Chemsex Drug Checking is not subject to any preconditions and the staff are bound by professional secrecy.

Contact or questions?

Do you have any questions? We are also happy to advise you without analysis. Do you have questions about chemsex, its mechanisms of action, consumption experiences, trends or the effects on your health? Do you want to stabilise, reduce or give up your sex consumption?

We will be happy to help you at
