distillation

Batches of an alcohol-based hand sanitizer were recently recalled due to contamination by methanol, which is too toxic to be used for this purpose. How did the methanol get into batches of alcohol? A look at moonshining can answer this question.
Perhaps we finally have an answer to what's causing serious lung damage and death to vapers. The CDC says the culprit is THC and/or an additive, something we explained last month. Here's why we think those officials are correct.
Although no official cause of serious, vaping-related lung injuries has been established, chemistry can enable us to make a reasonable guess. And it all goes back to a simple procedure that you may have done in high school chem lab: distillation.
