The article doesn't mention that the situation is tied to THC vaping (rather than nicotine vaping) until 5 paragraphs in, which strikes me as a dishonest way of playing in to the vaping hysteria. Similarly disappointing is the use of "e-cigarette market" to refer to black-market THC vaping cartridges; using "vaping" to refer to both is confusing enough as it is, without needing to deliberately misuse a term. I expect this kind of thing from clickbait Buzzfeed articles, not from Nature.
