> You have all sorts of metals, liquids, flavoring compounds, wicks, etc
Metal content is negligible unless you dry hit. No one likes that so it's pretty much a self-limiting problem.
Flavoring compounds, though... there are liquids out there that contain diacetyl (a "buttery" flavoring). It's relatively common in foods, but is known specifically to cause issues when heated and inhaled.
ETA: I just saw that this is mentioned in the article.
> Any one of those components could be harmful.
Yep. The best harm reduction strategy at the moment seems to be to stick to well-known and establish manufacturers of eliquid.
