Drug testing can provide concrete evidence against an employee for several reasons. There are several different types of drug testing and their results can vary depending on what the substance being tested is, how the substance is tested, and the quality of the sample. Drug testing experts are generally required by federal and state law to be licensed by the National Institute of Forensic Science. In order to obtain a license, the applicant must demonstrate scientific expertise in the particular area in which he/she desires to work as well as pass written proficiency examinations. Along with passing the licensing examination, applicants will also need to undergo drug testing under local anesthesia for accuracy.
Why Important Drug Testing?
When it comes to drug testing, most employers and law enforcement officials require that drug testing be conducted before an individual is hired or during an employment application. In some instances, such as with drug testing following the termination of an employee, employers may also request drug testing be conducted before a potential hire is hired. In these cases, the employee usually has the opportunity to agree to drug testing or may simply decline. In cases in which consent is not initially obtained, tests may be administered by a drug testing expert prior to or after consent is obtained from the individual.
When testing is performed during the hiring process, drug testing may be part of a background check as well as a pre-employment drug screening. Most employers conduct a drug screening when they pre-screen job candidates based on their personal information. Applicants who are denied employment based on drug screening results may have their application considered again by the same employers if they can show that they have passed or are likely passing the new drug screening. In many states, including California, drug testing is also an option for those who have been convicted of crimes involving the use or possession of illegal substances. Substance abuse by employees not only compromises safety on the job, but it also costs employers millions of dollars in legal and healthcare expenses.
