Bromobenzyl cyanide (BBC), also known in the military idiom as camite, is an obsolete lachrymatory agent introduced in World War I by the Allied Powers, being a standard agent, along with chloroacetophenone, adopted by the Chemical Warfare Service. It was thought to have been phased out in the 1930s, but has allegedly seen use in 2024, when authorities in the Republic of Georgia are said to have used it to quell anti-government protests.
