If I am fundamentally suspicious about what exactly the acquired cannabis product is

Analysis of the relationship between THC and CBD

When a constant dosage is important to me

When and how will I receive my result?

The analysis result can usually be viewed on Friday of the following week from 14:00 onlinein person on site or by telephone on +41 44 415 76 40 (between 14:00 and 17:00). The sample run number and the password agreed at the time of submission are required for this. If you no longer have this information, please call the above number.

What can be analysed?

Flower, hash, pollinate, extracts (such as oils, dab, dick extracts, e-liquids) and pure substances (such as pure CBD). Samples intended for medical use (e.g. oils containing CBD) are also accepted.

Cosmetics and "regular" food (tea, sweets, hemp beer, etc.) from the specialized trade are excluded. Exceptional cases, such as space cookies, where synthetic cannabinoids are suspected, can be analyzed qualitatively.

How it works

Cannabis flowers:
If small amounts are still present (at least 0.2 grams) and synthetic cannabinoids are suspected, qualitative analysis for extenders is possible, but no quantification of THC/CBD.

For quantification of THC/CBD content, grind/grind 2-3 grams of the flower and submit 1 gram for analysis. Stems should also be included (for a realistic content determination as well as for the detection of possible synthetic cannabinoids). The samples must be dry, otherwise a realistic content determination is not possible and there is a risk of the sample becoming moldy.

Hash:
If small quantities are still present (at least 0.2 grams) and synthetic cannabinoids are suspected, a qualitative analysis for extenders is possible, but no quantification of THC/CBD.

For a quantification of the THC/CBD content, grind/grind 0.5 grams (if this is possible from the consistency). With smaller sample quantities, optimal analysis becomes difficult.

Oil/Dab/Liquid:
Varies, smaller quantities are generally required for highly concentrated samples.

- For the ampoules, we need at least 2ml; if possible in closed ampoules (if the ampoules have already been opened, there is a risk that germs will form or have formed, which can lead to abscesses if consumed intramuscularly. Germs and other bacteria cannot be analyzed by our laboratory)

- For AAS in tablet form, we need 5 tablets; due to the often imprecise production in the laboratory, the active ingredients, quality and content of each tablet can vary massively.

- We can analyze the sympathomimetic clebuterol. We need one tablet.

The sample material provided is used in its entirety for laboratory analysis and is not returned.
