Mace Pepper Spray is an inflammatory agent...not an irritant and because of this people that normally would not feel pain because they are psychotics or under the influence of alcohol and/or drugs DO FEEL the effects of Mace Pepper Spray! Mace Pepper Sprays have a powerful Oleoresin Capsicum (OC) pepper formula that creates an intense burning sensation and causes an attacker's eyes to slam shut upon direct contact. OC pepper is a naturally occurring substance derived from cayenne peppers. The effects will last anywhere from 15-60 minutes and can result in temporary blindness, shortness of breath and coughing! Protect yourself with Mace Pepper Sprays!
