Drug checking for sexualised substance use

On the first Monday of every month, you can have your psychoactive substances that you want to use at sex parties, during chemsex or for a sex adventure tested free of charge and anonymously at Checkpoint. A cooperation offer by saferparty.ch and the Checkpoint.

How’s it going?



You can register anonymously by phone or directly online (see below). The offer is exclusively aimed at people who use or would like to use psychoactive substances for sex. If you would like to use substances for recreational drug use without sex, please use the services of the Drug Information Centre of the City of Zurich.


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 be called with this number. Your anonymity is guaranteed, no one in the waiting room will be able to tell that you are there for drug checking.



You have a counselling interview with a professional who specialises in psychoactive substances. The interview is documented at the first visit to Drug Checking for Sexualised Substance Use 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. One substance per person can be handed in for analysis.



You can ask for the results of the analysis by phone (044 415 76 46). If you have something tested on Monday, you will have the result on Friday of the same week. Results can be requested by telephone on Friday, 3 p.m. to 6 p.m.

What do we offer?

You can talk to us about sex on drugs in a moral and value-free way. We will inform you about the effects and risks of psychoactive substances that you consume before or during sex or at parties and sensitise you to the possible consequences 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.

These substances can be analysed quantitatively and qualitatively (PDF)

The offer is anonymous and free of charge. A counselling interview is conducted with each person who submits a substance for analysis. A counselling interview is conducted with each person who submits a substance for analysis. The staff members 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 sexualised substance use, chemsex, their mechanisms of action, experiences of use, trends or the effects on your health? Or would you like to know more about the substances you use? Would you like to stabilise, reduce or completely stop your consumption during sex or in everyday life?

We will be happy to help you at chemsex@zuerich.ch
