EVALI was a 2019 case cluster of acute lung injuries, largely confined to the US. It was (reluctantly and belatedly) verified to be caused by contraband THC vaporizer cartridges, diluted with vitamin E oil (tocopheryl acetate). The CDCs opportunistic misattribution to nicotine e-cigarettes started the anti-vaping hysteria. But necessitated auxiliary lies for early e-cigarette bans in the US.

Notably the origin cause was long documented by independent journalists, researchers, the FDA, vaping and cannabis industry. But the CDC purposefully rescoped the acronym, misdirected investigations, while guising themselves as being "data-driven". The intentional smear campaign required leaving THC users in the dark, thus raising the death toll to 68. Until a real pandemic forced the CDC to resume public health activities.

Misnomer king

The redeclaration from "VAPI" to "EVALI" was largely driven/promulgated by Dr. Brian A. King of the CDC OSH. (He also misconstrued summary reports to validate the flavour-fallacy). Notably his job would normally entail making scientific details more understandable to the general public. Looks like he took ergo-harmful to a whole new level:

KING: this is brian king. We do know that e-cigarettes do not emit a harmless aerosol. they can include a variety of potential harmful ingredients, including ingredients that are harmful in terms of pulmonary illness. That said it’s possible that the reported cases could have been occurring before this investigation was even initiated in an event that we weren’t necessarily capturing them, but now there’s increased diligence in terms of the current investigation that we’re better able to capture those. That being said, the available science does suggest that the constituents in the aerosol could be problematic. We know there’s a variety of intended and unintended constituents in these products so as we continue with the investigation it’s important to keep all options open and identify a variety of ingredients. At present we haven’t isolated a specific source but we know there’s a variety of constituents in e-cigarette aerosol that could be problematic in terms of illness. RW: 2019-08-23 telebriefing on severe pulmonary disease associated with use of e-cigarettes

Later continued with a diatriabe on ultrafine particulates, heavy metals, diacetyl; shortly acknowledging THC use, before resuming the long-held disdain for e-cigarettes. Which is how the "association" of e-cigarettes in the rescoped acronym is explainable from public information.

Argumentation patterns

  • Rescoping to "EVALI" (E-cigarette and Vaping Associated) allowed the FUD campaign on e-cigs.
    • It's only "associated" on technical grounds. Wilful misassociation.🟥
    • Claims resting on acronym regurgitation are often intent on misleading.
  • Conflating "vaping"
    • "Vaping-associated" is a weasel phrase to confound e-cigarettes (commonly called "vaping") with THC vaporizers (which absolutely no-one refered to as "e-cigarettes" or just "vaping")
    • It's clearly a false equivocation🟥 built right into the rescoped acronym.
    • A bit symptomatic of American linguistic decay and redefinitions.
  • More importantly, neither "e-cigarettes" nor "vaping" were terms that would elicit the warranted attention from Cannabis users. Only the FDA seemed genuinely concerned with the rising hospitalization and death toll caused by ambiguous PH messaging.
  • Data-driven was an euphemism to disregard prior research/findings.
    • Origin cause was long documented by leafly magazine.
    • But CDC rather insisted on starting from zero.
    • In conjunction, delayed investigation results were also explained with outmodded IT systems.
  • Not ruling out anything was a common phrase to keep the broadened scope, implicate e-liquids and prolong the investigation for the long-desired opportunity to uncover something scary.🟧
  • Patient self-reports weren't questioned. Albeit it would have been apt to point out the social, criminal and insurance ramnificatitons on THC use in some states.
    • Schuchat reluctantly alluded to that once/partly (IIRC).
    • Which has been amply utilized by CtFK/PAVe to continue the talking point of "But Xy% reported only using nicotine/e-cigarattes". "So they could be responsible for the deaths anyway!"
  • Delayed guidelines for testing on THC.🟥
    • (Was there a specific talking point on this?)
  • "The CDC recommends that e-cigarette, or vaping, …" was core to public messaging.
    • Still not disambiguated, btw.
  • Mixing was a conflation excuse later on.
    • CDC prolonged the research of probable contaminants, but then presumed(?) mixability (oil in water-soluble VG/PG nicotine e-liquds).
    • Kitchen expertise: nil-pwa. 🟨
    • Probably also scattered by WHO, and parroted ever since (e.g. SPD).
  • Notably "ENDS" (oft used as derogatory terminology) was largely absent from most publications.

Reckless media reporting (CNN et al.)

Sementically the implication of e-cigs in lung injuries wasn't far off from "vaccines cause autism". A couple of months later, the same media organizations are feigning confusion on where anti-masketeers/anti-vaxxers might have drawn their legitimization from, or where the distrust in public health orgs/messaging was furthered.

Utilized as core rationale for anti-vaping legislation

Different device types, btw

This also seems somewhat lost on some. But THC vaporizers aren't even technically e-cigarettes. They look similar (oftentimes older eGo-class pen devices), but require different atomizers for THC liquid (MCT oil base). For its higher viscosity, ceramic coils are necessary. The cotton+heating wire setup in e-cig atomizers are only reliable with PG/VG mixes (water-soluble). It's fairly rare to have PG/PEG400 liquids that would even work in common e-cigarette atomizers, because THC doesn't stay diluted for long therein.

[maybe needs a picture]

Wikipedia kept it alive

This is fairly interesting, from a technical standpoint. Albeit mostly resolved now, some activist slant found its way into WP articles on e-cigarettes and EVALI.
