A Vaping Illness That’s ‘Becoming an Epidemic’

If they are extracting from trim and other low-value parts of the plant, yeah that is a possibility. Myclobutanil has a boiling point around 200 C, THC around 155 C. They have similar hydrophobic nature. So any extraction process favoring THC will also likely partition myclo. If you are making concentrate from buds, this isn't an issue, as your ratio of active components to pesticide is going to be similar. However if you are extracting low-density plant matter, your ratio of myclo to actives will be higher.

However, the highest number I've seen reported was just shy of 1 ppm myclobutanil. Not great, but that's still pretty low.

I've seen 700ppm total pesticides and typically between 50-300ppm in the CA medical market of 2015-2017. Myclo up to 150ppm was pretty common in the crude I was testing. I tested at SClabs, Anresco, Steep Hill, CW Analytical, etc. depending on client preferences.

Is this specific to vaping supplies, or would it also impact CBD oil tinctures?

Got it. Thanks for the extra reference. Definitely seems like it’s a moot point and something else is at play, giving more credence to the OPs speculation.
