Signs That a Person Is Using Cocaine: Signs of a Person Using Cocaine

Cocaine is a strong stimulant that affects the central nervous system. It is the opposite of a depressant in that it speeds up the body by escalating heart and respiratory rates and raising the blood pressure. This results in a feeling of high alertness, intense energy and insomnia.

Cocaine, crack cocaine or in any other form, are illegal.

Like depressants, stimulants are often abused and cause as many problems as illicit drugs. Cocaine (called “crack” in another form) is the most popular stimulant used by 1 percent of Americans. It is one of the fastest-acting and most powerfully addictive drugs. Cocaine is generally available in white, crystalline powder form, while crack, called a rock, is in a white to tan solid form. Cocaine is normally snorted but may be dissolved in water and injected. Crack is usually smoked, with the fumes being inhaled.

Cocaine and crack stimulate the brain and nervous system. They increase the heartbeat and constrict the blood vessels. Use of cocaine or crack may cause seizures, cardiac arrest, respiratory arrest or a stroke. Death by heart attack may result with any use, even first time use, for people of any age.

Cocaine gives the user a heady rush. The user generally becomes unusually energetic and alert, loses interest in food, and has no need for sleep. The immediate symptoms are mixed; the user might become unusually talkative, self-confident and in control. Or the user could experience anxiety, become quickly irritable and unhappy. Physical symptoms are a sudden increase in heart rate and blood pressure, an increase in breathing rate and body temperature, a dry mouth, dilated pupils, exaggerated movements and a stuffy or runny nose.
