Plant defense against herbivory which differ from one another in both functional groups, and in basic carbon skeletons. Monoterpenoids, continuing 2 isoprene units, are volatile essential oils such as citronella, limonene, menthol, camphor, and pinene. Diterpenoids, 4 isoprene units, are widely distributed in latex and resins, and can be quite toxic. Diterpenes are responsible for making "Rhododendron" leaves poisonous. Plant steroids and sterols are also produced from terpenoid precursors, including vitamin D, glycosides (such as digitalis) and saponins (which lyse red blood cells of herbivores). Phenolics, sometimes called "phenols", consist of an aromatic 6-carbon ring bonded to a hydroxy group. Some phenols have antiseptic
Bath salts (drug) Bath salts (drug) "Bath salts" (also "psychoactive bath salts", "PABS", or in the United Kingdom monkey dust) is a term used to describe several recreational designer drugs.

The drug's packaging often states "not for human consumption" in an attempt to circumvent drug prohibition laws. Recreational drugs have also been disguised as plant food, hookah cleaner and other products. Synthetic cathinones such as mephedrone, which are chemically similar to cathinone,
