As an employer, an employee, or otherwise curious citizen, it may interest you what kind of drugs and how long after the drug has been used a drug screening is able to detect. The drug testing industry has come a long way from its obscure days of its infancy and has now become an accepted practice amount large companies and small businesses alike. Since the time of having drug testing a more accepted means of the hiring process, companies have a seen a decline of work related accidents and a decline in health care costs.
Used primarily as a means of detection and screening for employment, the main types of drug tests used are urine analysis and hair follicle testing. Each form of testing can detect different substances for a different length of time. This has to do with how the body breaks down certain metabolites that drugs leave behind after use.
We have listed below the most commonly abused drugs and how long they are detectable by conventional drug tests:
- Alcohol: Urine- 6-24 hours | Hair- up to 2 days
- Amphetamines: Urine- 1-4 days | Hair- up to 90 days
- Methamphetamine: Urine- 3 to 5 days | Hair- up to 90 days
- MDMA: Urine- 72-96 hours | Hair- up to 90 days
- THC: Urine- up to 30 days or more | Hair- up to 90 days
- Cocaine: Urine- 2 to 5 days | Hair- up to 90 days
As mentioned earlier, these are the numbers in regard to the most commonly used drug tests. Blood testing, another form of drug testing, is designed to indicate whether a person is under the influence of drugs as the test is being taken and can elicit an immediate result.
