The effect of "Mace" or "Pepper Spray" varies on humans. Most common is a burning sensation on the area affected with the spray (described by some as "having your face drenched in gasoline and lit on fire"). If in contact with eyes it causes automatic closing of the eyes due to intense pain if open. This along with a feeling of suffocating if inhaled it causes the person to be very vulnerable and dependent, resulting in easy overpowering (for example, law enforcement officials over a criminal). Effects can be minimal on those under the influence of alcohol or drugs. The duration of the effects vary from 30 minutes up to 2 hours, depending on the person and treatment.
