Sources & methodology

Official source and limits

This is an information guide. It does not claim a CannabisLabor.ch location, partnership or private sample acceptance. Official food control and a private cannabis test are different activities.

• Zurich: Kantonales Labor Zürich

  Zurich's cantonal laboratory combines business inspections with food and consumer-product examinations; its remit also includes tobacco products. Establish the product category before asking about responsibility. This official role does not establish a private cannabis-testing offer.

• Bern: Kantonales Laboratorium Bern

  Bern's laboratory lists inspections, market surveillance and laboratory examinations among its tools. Its remit includes food, consumer products and environmental safety. An official assessment must be distinguished from a privately commissioned batch analysis.

• Lucerne: Dienststelle Lebensmittelkontrolle und Verbraucherschutz Luzern

  Lucerne has its own Food Control and Consumer Protection service. It treats food, consumer products, chemicals and tobacco products as separate topics. Being in Central Switzerland does not place Lucerne under the Laboratory of the Original Cantons.

• Uri: Laboratorium der Urkantone

  Uri refers to the Laboratory of the Original Cantons as its joint institution. It serves Uri, Schwyz, Obwalden and Nidwalden. A shared official laboratory is neither a CannabisLabor.ch sample collection point nor a confirmed cannabis service.

• Schwyz: Laboratorium der Urkantone

  Schwyz describes the Laboratory of the Original Cantons as a public-law body shared by four cantons. Its listed tasks include food, water and environmental analysis. This describes official responsibilities, not acceptance of private cannabis samples.

• Obwalden: Laboratorium der Urkantone

  Obwalden shares the Laboratory of the Original Cantons with Uri, Schwyz and Nidwalden. Official analytical responsibilities therefore extend across cantonal boundaries. Private testing still requires separate confirmation of acceptance conditions and suitable methods.

• Nidwalden: Laboratorium der Urkantone

  Nidwalden's concordat distinguishes the laboratory's core duties from possible related commercial services. Such services must not impair its main responsibilities. This general possibility does not establish currently available cannabis testing.

• Glarus: Amt für Lebensmittelsicherheit und Tiergesundheit Graubünden/Glarus

  A Glarus notice dated 20 January 2026 documents joint ALT controls for Glarus and Graubünden. It provides a concrete source for current collaboration. Its catering samples establish nothing about cannabis batches or private sample acceptance.

• Zug: Amt für Verbraucherschutz / Labor AVS Zug

  Zug's AVS laboratory offers examinations for third parties only where technical, time and staffing capacity permit. Its examples include food, consumer products and water samples. This does not establish general acceptance of private cannabis products.

• Fribourg: Service de la sécurité alimentaire et des affaires vétérinaires (SAAV)

  Fribourg's SAAV distinguishes chemistry, food-biology and veterinary-biology laboratories. Apart from drinking-water analyses, it generally does not test for individuals or businesses. Its official laboratory description must therefore not be read as acceptance of private cannabis testing.

• Solothurn: Kantonale Lebensmittelkontrolle Solothurn

  Solothurn describes site inspections and examinations in two laboratories as parts of its food-control work. Its page also provides a document on conformity assessment considering measurement uncertainty. This helps distinguish an official decision from a measurement alone.

• Basel-Stadt: Kantonales Laboratorium Basel-Stadt

  Basel-Stadt lists two analytical laboratory divisions and separate food and chemical/biosafety inspection units. Its remit concerns Basel-Stadt canton. A Basel research project or official laboratory does not replace method checks or confirmation of private sample acceptance.

• Basel-Landschaft: Amt für Lebensmittelsicherheit und Veterinärwesen Basel-Landschaft

  Basel-Landschaft has its own Food Safety and Veterinary Office and cantonal laboratory. The laboratory supports food and environmental enforcement analytically. Liestal and Allschwil must therefore be distinguished administratively from Basel-Stadt; neither authority is presented as a CannabisLabor.ch partner.

• Schaffhausen: Interkantonales Labor AR/AI/SH

  The Intercantonal Laboratory is based in Schaffhausen and handles food and chemicals duties for three partner cantons. It additionally lists environmental duties for Schaffhausen. Its location alone does not mean private cannabis samples are accepted.

• Appenzell Ausserrhoden: Interkantonales Labor AR/AI/SH – Lebensmittelinspektorat beider Appenzell

  Appenzell Ausserrhoden names the food inspectorate for both Appenzell cantons in Herisau as the first local enforcement contact. More complex examinations can use the shared laboratory in Schaffhausen. The local inspectorate and analytical laboratory are therefore different locations.

• Appenzell Innerrhoden: Interkantonales Labor AR/AI/SH

  Appenzell Innerrhoden is one of the Intercantonal Laboratory's three partner cantons alongside Appenzell Ausserrhoden and Schaffhausen. Its food-law remit also includes consumer products. The joint authority is not a confirmed private testing provider for every cannabis product.

• St. Gallen: Amt für Verbraucherschutz und Veterinärwesen St.Gallen

  St.Gallen's AVSV examines drinking water, food and consumer products for microbiological, chemical or sensory quality. Cantonal responsibility differs from the individual municipalities covered by a cannabis pilot trial. A study name does not establish a region-wide laboratory service.

• Graubünden: Amt für Lebensmittelsicherheit und Tiergesundheit Graubünden

  Graubünden's ALT describes risk-based inspections and consumer-product analyses as official controls. Its scope includes items such as cosmetics. Hemp products should therefore first be described by their intended use, rather than only their plant origin.

• Aargau: Amt für Verbraucherschutz Aargau

  Aargau describes risk-based samples from sales and production and chemical and microbiological examinations. Product labelling is also checked. Selecting an official sample therefore serves a different purpose from a privately planned batch comparison.

• Thurgau: Kantonales Laboratorium Thurgau

  Thurgau identifies official food examinations as its central task. Its page allows company or individual requests only exceptionally and after consultation. Sampling and the analytical question therefore need prior clarification; cannabis testing is not promised.

• Ticino: Laboratorio cantonale Ticino

  Ticino's Laboratorio cantonale identifies health protection and prevention of deception in food and consumer products as its main tasks. Its remit also includes bathing-water hygiene. These official duties do not establish private cannabis sample acceptance in Lugano or Bellinzona.

• Vaud: Office de la consommation (OFCO) Vaud

  Vaud's OFCO brings together food inspection, cantonal weights and measures and the cantonal chemist's laboratories. Its listed food and water services are in Epalinges. Cantonal responsibility must be distinguished from a research project limited to Lausanne.

• Valais: Service de la consommation et affaires vétérinaires (SCAV) Valais

  Valais's SCAV states in its FAQ that it does not handle private testing requests outside drinking and shower water. For other analyses it refers to private laboratory directories. The cantonal laboratory's existence is therefore not a cannabis sample-shipping recommendation.

• Neuchâtel: Service de la consommation et des affaires vétérinaires (SCAV) Neuchâtel

  Neuchâtel's SCAV describes samples originating mainly from cantonal, intercantonal or national official controls. Its page requests prior contact for other analytical questions. An appointment or desired parameter is not yet a confirmed cannabis examination.

• Geneva: Service de la consommation et des affaires vétérinaires (SCAV) Genève

  Geneva's SCAV is the cantonal control authority for food, consumer products and veterinary matters. Its topics also include cosmetics and tobacco products. This cantonal role differs from cannabis research documented in Vernier and from privately commissioned testing.

• Jura: Service de la consommation et des affaires vétérinaires (SCAV) Jura

  Jura's SCAV separates consumption and veterinary sections. Consumer protection covers food and consumer products, with its published office in Delémont. A cantonal control responsibility does not establish a commercial cannabis-testing service.

• Zurich

  UZH describes Züri Can as scientific research and, in its 8 October 2026 update, reports an approved extension to October 2028. This is research context, not evidence of a publicly accessible testing laboratory or open recruitment.

• Winterthur

  Winterthur is expressly listed as a municipality in the FOPH's Cannabis Research Zürich record. This project differs from Zurich city's Züri Can study. Listing does not establish unrestricted participation or a private testing service in Winterthur.

• Basel

  According to the FOPH, WeedCare studies regulated sales in selected Basel-Stadt pharmacies. Research into consumption and counselling differs from analysing a privately submitted product sample. It does not establish a CannabisLabor.ch testing offer in Basel.

• Bern

  The FOPH's SCRIPT dossier lists Bern as a study municipality and home of several participating university institutes. Its published planned period ends in April 2026. The record provides research context, not confirmation of ongoing recruitment or private sample acceptance.

• Biel/Bienne

  SCRIPT explicitly names Biel alongside Bern and Lucerne; this does not cover all Bernese municipalities. The published planned study period ends in April 2026. A documented study connection is not a current analytical service for Biel/Bienne.

• Lucerne

  Lucerne is SCRIPT's listed municipality in Lucerne canton, and the University of Lucerne is involved. The FOPH record gives April 2026 as the planned study end. These research details do not promise testing or sample acceptance in the city.

• Lausanne

  The FOPH describes Cann-L as research into a non-profit sales model in Lausanne, conducted by the city and Addiction Switzerland. This is a city-based research context. It establishes neither canton-wide testing nor a laboratory partnership with this platform.

• Vernier

  The FOPH explicitly locates La Cannabinothèque in Vernier and describes an association model involving ChanGE. Geneva canton must therefore not be confused with Geneva city. This study connection is not an open laboratory service or acceptance of personal products.

• Liestal

  Liestal is named with Allschwil in the FOPH's Grashaus Projects dossier. It describes research involving structured sales in specialised shops, not a generally accessible testing laboratory. Private testing still requires separate acceptance and agreement on analytical scope.

• Allschwil

  Allschwil belongs to the Basel-Landschaft municipalities described in the Grashaus Projects record. Its specialised-shop model differs from WeedCare's pharmacy model in Basel-Stadt. Both research approaches must be distinguished from privately commissioned product analysis.

• Wil

  Wil is explicitly named in the FOPH's CanLeg record. Its research design addresses willingness to pay, product quality and different distribution channels. These questions must not be confused with an already available cannabis laboratory service in Wil.

• Rapperswil-Jona

  Rapperswil-Jona is among CanLeg's listed municipalities; the canton name alone does not sufficiently describe its study area. The FOPH calls it a randomised controlled trial. Neither unrestricted participation nor acceptance of personal samples by CannabisLabor.ch follows.
