[CS tear gas spray as an injurious agent. Clinical aspects].

Eight cases are described, in which illegally imported CS-tear gas spray ("self-defence spray") were used in connection with malice or robbery. Analysis of the content of the sprays revealed small amounts of CS (0.2 per cent), but large amounts of solvents and propellants. The latter are presumed to have contributed to the symptoms. Exposure to CS-tear gas spray is usually harmless, but skin manifestations such as ulcerations, Quincke-like oedema in the face and allergic dermatitis have been reported by other authors. Theoretically, CS-particles may adhere to the cornea. Examination of the eye is therefore recommended.
