We had an interesting response from a reader, regarding last the previous newsletter email (shared with permission, edited for clarity):
Thank you for your email, and very interesting case. Please note below my thoughts:
- The Commissioner in this case, in my opinion, has erred in the decision and the decision should be set aside.
- No empirical evidence was presented to suggest the donor had indeed consumed Cannabis, other than his admission. He may have purchased “oregano”.
- The onsite test is indicative only. Several other drugs can trigger a “not negative” result for the THC screen.
- Let’s assume the donor did indeed consume cannabis. There is no empirical evidence it had exceeded the cut-off (both onsite and confirmatory).
- Onsite at best works at +25% / -30% cut-off, more like +/- 50% cut off. This means the sample can be either not negative or negative between the range of 25 – 75 μg/L.
In my opinion, and if I was on the other side… this would have been a totally different decision.
