About drug testing
Most drug tests do not look for the drugs themselves but for the chemicals that remain in the body after the drug breaks down. These are called metabolites, and can be found in blood, urine, hair, sweat or saliva.
The most common test is urine analysis, which can detect traces of drugs for up to three or four days after they have been taken – or, in the case of cannabis, for several weeks after it has been used, especially in heavy users.
Drug testing will not tell you whether a person is currently under the influence of a drug, but it will tell you that they have taken it. Anyone who carries out drug testing must be accredited by the UK Accreditation Service and comply with the International Standard for laboratories (ISO 17025).

Why is workplace drug testing important?
Drug and alcohol testing highlights any potential substance misuse in the workplace. This can be harmful to your staff, especially in industries where substances may impair:
-
Operating machinery
-
Working with the general public
-
Health and safety decision-making
-
Driving vehicles
Investing in workplace substance testing looks out for your employees. This reduces the risk of injuries and accidents and contributes to productivity. Certain industries, such as health care and transportation, may also legally need to comply with drug testing regulations.
