A surgeon claimed that an alcohol-based hand wash had been responsible for a failed evidential breath alcohol test (EBA). He had been operating all day, went home, had two glasses of wine went out again, and failed an EBA. He argued that "the moderate amount he had drunk was not enough to have put him over the limit." He claimed that an alcohol-based hand wash had been absorbed by his skin. What was he doing? Drinking it?

One of the fictions of the "naive-greens" and other "irrationalists" is that "chemicals" are bad while natural products (non-chemicals?) are good. When asked if water is a chemical, and hence evil, and whether cyanide, nicotine or the botulism toxin, are natural and hence benign they change the subject. You might think that our classrooms are immune to such nonsense; in the November issue of Chemistry in New Zealand, Ian Millar of Carina Chemical Laboratories Ltd tells us we are wrong.
