What qualifications do you need to be a drug testing agent?

As an intermediary for drug testing, you need to obtain the qualification of intermediary. In many countries, it is not allowed to engage in intermediary work in a private capacity without intermediary qualification. At the same time, before organizing personnel to test drugs, it is necessary to obtain a power of attorney from the drug testing company. If someone organizes others to test drugs in a private capacity and profit from it, this behavior is usually regarded as illegal.

Please note that this is only a general answer, and the specific qualification requirements and legal provisions may vary from region to country. If you plan to work in a drug testing institution, I suggest you consult a local legal professional to get accurate and detailed information.
