OR issues health alert for 3 cannabis strains with pesticides

Oregon has issued its second health alert for cannabis contaminated with pesticides, flagging marijuana flower being sold at three dispensaries around the state.

Oregon has maintained a strict policy about pesticide use on marijuana. And, according to the Oregonian, the Oregon Health Authority has now found three strains of flower were contaminated.

 Some 30 customers bought “Dutch Treat” from Oct. 15-26 at the Flowr of Lyfe recreational store in Eugene. It was found to contain the insecticide spinosad. The two other strains, Pleeze and Dryzl, were both sold in North Bend and Salem in October. The strains were found to contain piperonyl butoxide, an ingredient commonly occurring in pesticides, according to the Oregonian.

The state is recommending customers destroy or return the marijuana to the store.

    spinosad is a natural substance made by a soil bacterium that can be toxic to insects. Cannabis sold in Washington State is labeled as containing spinosad. Can the industry agree what is a safe level?

      Any level agreed upon right now would be guesswork, as the requisite research has not yet been performed to determine what safe levels of any pesticide are on cannabis. That type of research typically takes years, from what I’ve been told by individuals who have performed such studies themselves with other crops. Furthermore, typical use patterns for cannabis remain largely unstudied and are changing every day due to new products; this creates an issue when considering things such as the accumulated toxicity of substances, which is related to how much, how often, and how in general (smoking, vaping, eating, topical application, etc) people consume the product. For example, if one were to say 2 ppm of spinosad is safe – just as a hypothetical scenario, mind you – is that for an individual consuming 1 oz of cannabis a month via smoking? What about someone who smokes more? Will the compounds generated by combustion accumulate in the body to a greater degree and become more harmful? What if a different consumption method is being employed altogether? Lots of questions that will take years of impartial study need to be addressed before the seemingly simple question you posed can be answered.

    please research chitosan extract products.
    super organic and healthy for humans and plant roots soil health.
    yes thats right ……. shrimp shells are the hiding inert ingredient on the labels. please see enzymes, polymers, magnesium and other sneaky words

    shrimp shells folks….shrimp shells will make oil production in the plants

    examples…. flying skull nukem, budfactor x, big time enzyme, procidic2
    and many others

    a great tank mix in your IPM program is:
    serenede = brewers yeast
    azomax = neem oil
    procidic 2 and flying skull nukem bud factor x, ed rosenthols, nature cide all = chitosan based products

    pyrithrin = mum oil but will need masks and a pesticide applicators certificate

    all organic and please no spray policy on flowers in bloom

    I would assume with all the years of tobacco cultivation behind us, things like what pesticides are acceptable for smokable products would have already been figured out. I don’t understand how this is some sort of new issue.
