Do you think that pesticide use could be a contributing factor as well? I ask because my hemp mentor will never touch concentrates. He argues that even the tiniest bit of pesticides or inorganic fertilizers will also be more concentrated and he’s not willing to gamble on it. There’s just too many unknowns when it comes to that.

So you’re a hemp protégé?

  I guess you could say that. I’m in my first year as a farmer growing hemp. It’s pretty fun and interesting stuff!

    You should write something up and submit it here. I'd read it for sure.

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. https://www.thestranger.com/slog/2018/12/20/37272899/no-one-will-take-responsibility-for-this-pesticide-ridden-vape-cartridge https://www.thestranger.com/slog/2018/12/20/37272899/no-one-...

  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.

  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?

No, I don't. There's some talk about neem oil(azadirachtin) being the cause of cannabis hyperemesis syndrome. People have been consuming large quantities of cannabis oil that were saturated in pesticides for over a decade without this kind of crisis. I run a cannabis copacking company and one of my clients was the first to go pesticide free back in 2016. It was near impossible to source material for them. Prior to 2018 about 95% of material was sprayed with pesticides. Because black market distillate is typically made from mixed batches of oil there was higher contamination rates than that. I think it's questionable to consume cannabis in general and especially concentrates. The safest method is likely oral consumption. I have seen contaminants in concentrates, such as fire retardant, that pass all screening tests. Neem oil, for example, is an approved pesticide for CA but is really nasty stuff to be smoking.

  > People have been consuming large quantities of cannabis oil that were saturated in pesticides for over a decade without this kind of crisis. This. People have been vaping THC e-cig cartridges for years. Same for using other concentrated products like wax. Yet it seems only very recently that this has become some kind of 'epidemic'. I'm not saying that it's safe, but it seems very sudden that all these cases show up. Or maybe they were happening before, but because it seemed so hard to diagnose, people weren't connecting the cases?

My worst episodes of CHS I've had from smoking synthetic cannabinoids, I'm not aware of neem oil having any relevance in the production of those. Imho a large factor could simply be an overabundance of product leading to people overconsuming because "Cannabis has no negative effects", so nobody cares about basics like tolerance breaks anymore [0], instead people just keep upping their THC doses to get past their tolerance threshold.
