"The term “tear gas” is a misnomer. For one thing, “tear gas” seems to imply something innocuous— you would think it’s just a chemical that makes you tear up. In fact, tear gas is a dangerous, potentially lethal chemical agent which is outlawed under the Chemical Weapons Convention for use during wartime. As the Omega Research Foundation argues: “Less-lethal weapons are presented as more acceptable alternatives to guns. But these weapons augment rather than replace the more lethal weapons. Euphemistic labels are used to create the impression that these weapons represent soft and gentle forms of control. CS is never referred to by the authorities as vomit gas, in spite of its capacity to cause violent retching.” NGO Physicians for Human Rights believes that “ ‘tear gas’ is a misnomer for a group of poisonous gases which, far from being innocuous, have serious acute and longer-term adverse effects on the health of significant numbers of those exposed.”"
