  I can't disagree. Scientists clearly use the word, but I would say there is a great deal of specificity to their usage and a very general malleable unspecific usage in typical science journalism, but that is a lot to write out, sort of an 80/20 rule for using the word Toxins. Often enough you will be write, so don't treat it as an inviolate law, but a good rule of thumb perhaps?

  In biology, toxins are compounds that cause injury. The wording in the article implies that all waste products removed by sleep are toxic, which is unlikely. Many chemicals removed by sleep probably are not toxins, at least perhaps, not until they accumulate and form obstructions, like Alzheimer plaques.
