Pepper Spray and Mace

Pepper spray (which is also known as mace, OC spray, OC gas, capsicum spray, or oleoresin capsicum) is a chemical agent that, when sprayed, irritates the eyes and causes such painful physical symptoms as tears, pain, difficult breathing, runny nose, coughing and even temporary blindness. These deterrents are used by law enforcement in many situations including riot control, crowd control, suspect apprehension and personal self-defense. The physical effects of the spray on the individual cause temporary debilitation, which helps police officers gain control of unruly situations. Police also use TASERs for similar purposes, but usually only in more extreme circumstances. The chemical is also used by private citizens as a self defense and personal protection tool. The chemical spray is most often carried by women. The active ingredient in pepper spray is capsaicin, which is a chemical derived from the fruit of plants in the Capsicum genus, including chilies. In some cases, the spray can be lethal, especially when the dosage is excessive and in cases where the sprayed individual has heart problems, a respiratory illness, etc. The duration of the effects of pepper spray depend on the strength and amount of the chemical sprayed, but the average full effect lasts around thirty to forty-five minutes, with diminished effects lasting up to several hours. The long-term effects of the spray have not been adequately researched.
