Salutations,
In Québec/Canada the right to home cultivation has been confiscated, while landlords were granted a retro-active one to eviction by the PLQ as an electoral gift. The subsequent government only worsened the situation worse by restricting the number of state-monopoly outlets. In short our politicians nailed it, though there may be potential exceptions for individuals willing to register as "medical" clients at the federal level - a $i¢k 'n $ad capitulation that ain't no acceptable alternative to me.
So my personal experience with this hobby was very brief, although it left wonderful memories because the satisfaction alone is worth it. Then, « $anitory Addditive$ » made the news with the myclobutanil scandal revealed during the 2015 Christmas season. This made me highly critical of 3rd parties due to a glaring regulatory blind spot: a massive catalog of monitored ("non-detection") items and zero combinatorial C(n, r) restrictions. This implies that the numbers can become astronomical very quickly, for instance in here that's 96 + 10 or so items, the resulting range is around C(106, 12) = 2.200787712 x 10E15 or 2 200'787'712'000'000... More clearly, that's a health risk nobody can prove nor disprove: all savvy synergistic toxicities just can't get tested while the "traces" accumulate.
Here's a measure of how truly concerned our elites seem to be, pay special attention to the date of this document:
As of December 20, 2024, users of pest control products must strictly adhere to the clarifications provided regarding pesticides label instructions for tank mixes.

Health Canada guidance for tank mixes (2025-Dec-20)
A 10 years anniversary after our myclobutanil collective commotion, do you see the irony?
Or if you prefer it came 7 years after Justin Trudeau's (2018-Oct-17) « légaleezation » and only affects a much shorter list, quite likely because it finally addresses "Cocktail Effects" (a savvy mix is banned unless explicitly mentioned on one of the labels). It remains a "non-detection" concept, this one tagged as "MRL" (Maximum Residue Limits).
Sorted alphabetically it includes:
Bacillus thuringiensis (Bioprotec CAF or Plus)
Beauveria bassiana (Bio-Ceres G WP, BotaniGard)
Canola oil (Vegol)
Citric acid (Cyclone)
Gliocladium catenulatum (Prestop WP or WG)
Hydrogen peroxide + Peracetic acid (OxiDate 2.0)
Lactic acid (Lacto-San)
Metarhizium brunneum F52 (Met52/LalGuard M52 GR or OD)
Mineral oil (SuffOil-X)
Potassium bicarbonate (MilStop)
Potassium salts of fatty acids (Kopa, Opal)
Pyrethrins + Canola oil (Doktor Doom Formula 420)
Reynoutria sachalinensis (Regalia Maxx)
Streptomyces griseoviridis (Mycostop)
Streptomyces lydicus (Actinovate SP)
Sulphur (Agrotek Ascend, Microthiol Disperss, Kumulus DF)
Trichoderma harzianum KRL-AG2 (Rootshield HC or WP)
Trichoderma harzianum T-22 (Trianum)
Keep in mind that cannabis happens to be a bio-accumulator of which we inhale the noble molecules on a regular basis. Furthermore, these types of restrictions fail to address the potentialization occurring when "trace" amounts of banned substances interact with those approved additives; never mind mentioning the secondary/tertiary bi-products from thermal reactions!
To top it all off, destructive liquid & gas chromatography-tandem mass spectrometry screening would cost around a thousand dollars per batch, effectively rendering in vivo toxicity studies of potential synergies physically/financially impossible to conduct on a global scale.
It's just a leap of faith to me. This is essentially an administrative risk management strategy designed to maintain any potential synergistic "noise" theoretically below the biological radar. Our legal market’s propaganda focuses on stories of street weed getting sprayed, but it won't say a thing about the catalog size, trace levels and combinatorial figures.
My conclusion is that total control depends on proper soil management, PFAS-free water, etc., and that's exactly what's being denied in my $a¢rifi¢ed cannu¢k province. Given all this, how "safe" do you expect me to feel?
Good day, have fun!!
