Since its entry into force in 1997, the Chemical Weapons Convention (CWC) and its associated implementing body, the Organisation for the Prohibition of Chemical Weapons (OPCW),1 have become an important mechanism for global action combating the use of chemical weapons against armed forces and civilian populations under any circumstances, as demonstrated in Syria.
Riot Control Agents
Riot control agents, commonly known as tear gases, are defined by the CWC as “any chemical not listed” in one of three schedules of restricted chemicals that can produce “rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.”4 Their use as a “method of warfare” is specifically prohibited under the CWC.5 The convention, however, permits the use of such chemicals for “law enforcement including domestic riot control purposes,”6 provided they are used in “types and quantities” consistent with such purposes.7
If the OPCW does not take appropriate action, the situation could dramatically worsen as a result of ongoing development, marketing, and subsequent deployment of a range of systems capable of delivering far greater amounts of riot control agent over wider areas or more extended distances than currently possible with standard law enforcement RCA dispersal mechanisms, such as hand-held sprays, grenades, and single-projectile launchers.
In recent years, the OPCW, notably its Scientific Advisory Board, finally has begun to examine these issues. In 2012 the board raised its concerns regarding “reports of the commercial availability of munitions apparently designed to deliver large amounts of riot control agents over long distances.”23 To date, however, few states-parties have clarified their national positions in this area.
Although the use of appropriate types and quantities of riot control agents for law enforcement purposes is permitted under the CWC, certain countries have developed additional weapons employing other distinct toxic chemicals, notably so-called incapacitating chemical agents (ICAs). These weapons, which ostensibly are for law enforcement, skirt or breach the convention’s prohibitions.

15. After surrounding all exits, police fired tear gas into the stadium, causing fear and confusion among the tens of thousands of peaceful pro-democracy supporters within. The combined forces then entered the stadium, shooting directly at the packed and terrified crowds. According to an International Commission of Inquiry, “[D]ozens of people attempting to escape through the stadium gates either suffocated or were trampled to death in stampedes, which were compounded by the use of tear gas.” Human Rights Watch estimated that 150 to 200 were killed and dozens of women and girls were raped in this attack.
