Cocaine is a crystalline alkaloid obtained from leaves of the coca plant. It acts by stimulating the central nervous system. The National Survey on Drug Use and Health indicates that, as of 2008, over 5.3 Americans age 12 and older had abused cocaine. According to the National Institutes of Drug Abuse, cocaine's addictive properties are due to its ability to increase levels of chemicals that arouse pleasure. Cocaine use leads to feelings of euphoria and high energy. Individuals addicted to cocaine often try to hide their addiction, but there are warning signs that provide clues to the person's dependence.
Physical Signs
Physical signs of cocaine use are the most difficult to detect because they may not be noticeable to casual acquaintances. The stimulant effects of cocaine cause an increased heart rate and blood pressure, for example. Abuse of the drug can lead to noticeable signs like insomnia and irritability resulting from increased nervous system stimulation. Extreme weight loss is also a common indication of cocaine abuse because cocaine acts as an appetite suppressant. Bloodshot eyes with dilated pupils often arouse suspicion of use of the drug.
Psychological Signs
A cocaine abuser is likely to exhibit mood swings as drug levels fluctuate in the body. Anxiety is commonly seen because the user often does not know when he will be able to obtain more drug to achieve the desired high. With continued use, many cocaine users find that they are unable to complete day-to-day tasks without being under the influence. Also, a cocaine abuser may portray signs of desperation to get the drug, unable to fulfill work or home obligations.
Relationship Signs
When cocaine is abused, obtaining the drug is likely to become the sole focus of the user. Relationships suffer as a result. The individual may also resort to stealing or manipulating loved ones to obtain drugs. This leads to strained relationships with all involved. Withdrawing from or losing interest in loved ones is a painful sign of cocaine abuse.
