Drug Abbreviations Used in Drug Testing

Employee drug testing is a measure that aims to prevent the use of illicit drugs in the workplace, to keep this environment safe and healthy for all. It also discourages workers from drugs and alcohol abuse and allows quick actions to combat with such problems when part of an ongoing drug and alcohol policy coupled with actions such as random drug tests. In some circumstances of pre-employment, drug testing could help the employer to know the fit-for-work of a potential employee. Finally, drug testing is an important measure to take by the company to comply with regulation and potentially have discounts on the employees’ insurance premiums.

Because of small space on drug testing kit packages, drug tests usually mention only drug abbreviations. Knowing the abbreviations, slang names, and details (such as the dangerous effects they cause) of the drugs they represent can help you, as an employer, better understand the risks and reasons for testing for these specific substances. Whether you use 5-panel, 7-panel, or other testing, knowing the risks and exactly what you are testing for is vital to safe workplace.
