Cocaine is highly addictive drug of abuse. A recent NIDA survey stated that, approximately one in six Americans (15% in 2007), by the age of 30 tried cocaine. Cocaine directly affects brain and causes many health problems like heart attack, respiratory failure, strokes, and seizures. In some rare cases, sudden death can occur on the first use of cocaine.
Cocaine drug tests help people to examine their friends or family members and help them to stay away from abuse. The abuse can be detected by using urine, hair, or saliva drug testing methods. Cocaine can be detected for 3 days in urine, 90 days through hair and up to 2 to 3 days in saliva.
Urine drug testing:
The most common test to detect cocaine is urine test. Urine tests that detect cocaine are inexpensive and affordable. These tests can be done at home and they are intrusive in nature. Cocaine content can be detected for up to 3 days using urine tests and the recommended cut off level by SAMHSA is 150 ng/mL for initial test and 100 ng/mL for confirmation test.
Hair drug testing:
Hair drug tests to trace cocaine are highly reliable. Cocaine is usually traceable via hair drug screening for up to 90 days. Hair tests will work with any hair on the body, including facial hair and body hair. The SAMHSA recommended cut-off values for hair testing are, 500 pg/mg for initial test and 500 pg/mg for confirmation test along with at least 10 times benzoylecgonine concentration. The concentrations of cocaethylene or norcocaine should be greater than or equal to 50 pg/mg.
Saliva drug testing:
Detecting cocaine content using saliva is very quick and easy. This method is highly secured and difficult to adulterate. Sample of saliva is collected using a scrub and sent to testing. Results of saliva drug testing are almost instant. The recommended cut off values for saliva tests are 20 ng/mL for initial test and 8 ng/mL for confirmatory test.
Drug tests help to monitor people from cocaine abuse effectively. Now a days tamper proof kits are available, and labs usually do two tests of the sample, one is screening test and the other is confirmation test. These methods are quick, efficient, confidential, and reliable.
