Drug testing for cocaine

Cocaine is a powerfully addictive drug made from the leaves of the coca plant native to South America. Under federal law, it is classified as a Schedule II drug, a category for substances or chemicals with a high potential for abuse and with use potentially leading to severe psychological or physical dependence. Cocaine is one of the substances in the federally-mandated drug test panel. 
Cocaine is inhaled through the nose in powder form or smoked in crystal form (crack). Users may experience short-lived euphoria and excitability changing to depression, irritability, nervousness and tightness of muscles. Physical symptoms of cocaine use can include shallow breathing, fever, anxiety, tremors and possible death from convulsions or respiratory arrest. Dilated pupils, increased heart rate and elevated blood pressure are key indicators of use. According to research from National Institute on Drug Abuse, adults aged 18 to 25 years have a higher rate of current cocaine use than any other age group.
Employers can screen applicants and employees to help to deter drug use and keep their workplaces drug-free.
