Only a limited number of substances can be analyzed at Drug Checking on Langstrasse. The following substances (and their usual extenders) can be analyzed qualitatively (what is contained) and quantitatively (how much is contained):
A whole pill, a whole felt or two knife tips (30-50mg) of a powder are required for the analysis. For liquids, take the container (dripper, spray, etc.) from which you intend to consume the substance. If you want to have amphetamine pastes tested, you should dry them beforehand. Cannabis, other herbal samples and edibles are explicitly excluded. For these samples, please use the Drug Checking at Wasserwerkstrasse. LSD on sugar cannot be accepted in any of our offers. The sample material provided will be used entirely for laboratory analysis and will not be returned.
The analysis result can usually be obtained within 60 minutes either online or by telephone on +41 44 415 76 40 (Saturday night until 00:30). This requires the sample sequence number and the password agreed when the sample was submitted. If you no longer have this information, please call the above number.
