Drugs & Alcohol In The Workplace

The prevalence of drugs and alcohol in the workplace can have a major impact on your reputation and productivity as a company. Over a 1 year period, more than 20% of employees in the United Kingdom turned up to work coming down from the effects of drugs, and over 45% came to work either with a hangover or from the effects of alcohol (Global Drug Survey, 2014).

Not only can this affect employee performance within the workplace, but absences become commonplace and the probability of accidents increases. It’s important to implement the proper policy on drugs and alcohol to reduce these risks. Our team are experts at creating drug and alcohol policies fit for your business – get in touch to see how we can help!

Drug & Alcohol Test Procedure

There are 2 main forms of drug and alcohol testing used in the industry – instant testing and lab testing. We currently use both types of tests at David Barber Occupational Health, to ensure that our results are accurate and tailored to your requirements.

  1. Instant drug and alcohol tests are carried out in the workplace using a police-standard breathalyser and an instant urine drug test kit to test for 13 different illicit drugs (different industries may differ using different amounts of drugs to be tested). The breathalyser gives a standalone result, whilst the urine test gives a negative or non-negative result. In the event of a non-negative result, the sample is decanted into a lab sample tube and sent to our United Kingdom Accredited Service (UKAS) lab for further analysis.
  2. Standalone lab analysis is used for either confirmation of drug and alcohol results but can be used if the client specifies this. Lab tests will come at an additional cost.

Additionally, we are able to undertake with-cause testing for both drug and alcohol in the workplace, if there is legitimate suspicion for the test or if there has already been an accident that requires investigation we are on hand to get you the results you need as fast as possible, just contact our expert team today.

David is trained to UKAS-standard for drug and alcohol testing, and all our technicians have had training in-house to carry out testing with expertise. Our clients include Nikko Denko, Hinckley Point Power Station and Dacrylate Paints, to name but a few.

We are closely situated to the new East Midland Gateway on the Nottinghamshire, Derbyshire and Leicestershire borders, and we’re always on-hand to travel, capable of performing tests at our office or on-site.

Drug & Alcohol Testing Laws

There are a range of laws around drug and alcohol testing in the workplace, and we make sure that both our team and the companies we work with adhere to legislation every time. In order to carry out a drug test on employees, you first need their consent. Provided you included a policy on drug testing in the initial contract of employment, they will have agreed to this when they signed the contract.

If an employee refuses a drug test even after they have given consent, disciplinary action may be taken if there are good grounds for testing. The test is usually counted as a positive if they refuse consent.

Furthermore, employers must limit drug testing only to the employees that need to be tested and ensure the tests are completely random. You cannot single out particular employees for testing unless the nature of their jobs justifies doing so.

The initial results are either negative or non-negative. The samples are then sent to the lab for further analysis to see if the levels are above the minimum levels under EU legislation.

This depends on the type of drug test you opt for. Our instant tests are carried out in the workplace so that we can provide you with results that same day. Standalone lab analysis, on the other hand, can take around 24 – 48 hours depending on when the testing is carried out. For example, if carried out on a Friday, the results will be Tuesday. If carried out on a Monday, the first samples will be available Tuesday with levels on Wednesday or Thursday.

Yes, our drug and alcohol tests are extremely extensive. Each drug has its own unique chemical structure so that when we analyze results there is no way to confuse one drug with another. Therefore a prescription drug will never give a positive result for an illegal substance.

The amount of time a drug will remain in your system depends on the type of drug consumed, the dose as well as the individual’s characteristics such as their sex, age and their weight. Many drugs will remain in your system for up to 4 days, but this can be longer.

In a similar way to a pregnancy test. The sample sticks identify traces of the drug being tested for and provide a line in the window of the test kit.

We have an example drug and alcohol policy on our resources page you can view and download. Alternatively, get in touch with our team and we can talk through your needs and requirements to write you a bespoke drug and alcohol policy that is suited to your business.

If one of your employees fails their instant drug & alcohol test in the workplace, we may use a standalone lab analysis for confirmation of results. However, what happens to the employee is really down to what is stated in your drug and alcohol policy. Make sure your employees are fully aware of your policy towards drug and alcohol abuse and ensure they know the consequences if they fail to pass.
