Pepper spray is a type of inflammatory agent and Mace is classified as an irritant. Mace is similar in classification to tear gas, which causes irritation of the eyes and face without causing another reaction. Pepper spray causes inflammation, which can immediately incapacitate anyone with whom it makes contact.
Mace can cause six different physiological effects to the skin, nose, mouth, eyes, chest and central nervous system. It can cause stinging and burning to the face, irritation, tearing and discharge from the eyes and nose. It can cause a tight feeling in the chest and coughing and the acceleration of saliva secretion in the mouth. It can also cause dizziness, headache and a general period of extreme discomfort.
Pepper spray can cause four different physiological effects to the eyes, respiratory system, skin and muscle coordination. The capillaries in the eyes dilate, the eyes tear up and close involuntarily and the eyes appear red or bloodshot for up to 60 minutes. The respiratory system becomes inflamed, the throat lining swells, the airway is reduced, the larynx is temporarily paralyzed and gasping, gagging, retching and coughing may result. Exposed skin becomes inflamed and experiences a burning sensation. Pepper spray can also affect muscle coordination, causing loss of balance.
Assailants under the influence of drugs and alcohol are not affected by Mace or tear gas. Pepper spray does affect individuals under the influence because of the physical response that pepper spray creates, rather than simply irritation. For this reason, Mace is safer, but less effective in self-defense situations when compared to pepper spray.
Use Mace and pepper spray with care, as both can pose harm if used improperly. Seek self-defense training to learn how to properly operate a Mace or pepper spray canister. Check with local laws and regulations to find out what self-defense sprays are legal in your area. Some laws prohibit the use of these products or require that you undergo training before using them.
