Drug testing new hires – how to build the procedure correctly
Drug testing new hires as part of the recruitment process: when it is OK to require it, consent in the employment contract, GDPR aspects and the right sample type.
Drug testing new hires is one of the least controversial elements in the entire testing field – if it is done correctly. It is preventive, transparent and helps you ensure that the person starting is drug-free from day one. Here is how to set up the procedure. For broader background, see our guide on the employer's right to drug test.
Is it permitted?
Yes, if it is communicated in the policy and in the job advertisement, if it is objectively justified (safety role, industry standard, client requirements) and if the process is legally sound. For new hires, the question of consent is simpler than in ongoing employment – the candidate can choose not to apply for the position if they do not accept the condition.
When should the test be carried out?
Two common models:
- Before the employment contract: the hiring decision is conditional on a passed test. Most common in safety-sensitive roles.
- After the employment contract but before the start date: the employment contract is signed but starting work is conditional on a passed test. Most common when recruitment is under time pressure.
Where in the process should the test appear?
- In the job advertisement: a short statement that the position includes a drug test before starting
- In the first interview: mentioned verbally
- In the employment contract: a written clause
- At the test: informed consent before sample collection
Transparency at every stage is central – and should be grounded in your alcohol and drug policy.
Which sample type?
Urine samples are the most common for new hires, as this is established practice and gives a wide detection window. Saliva tests are a common alternative when you want quicker and more privacy-friendly sample collection.
Panel – which substances?
A standard 5-panel usually covers amphetamine, cocaine, opiates, benzodiazepines and THC. For broader coverage, Provsvaret also offers laboratory-based panels analysing up to around 60 substances, tailored to the organisation's risk profile, the position and the need for legally sound verification.
Confirmation and MRO
As with all serious drug testing: positive rapid results must be confirmed in the lab and pass MRO review before being reported to HR. This is especially important for new hires because the consequence (a withdrawn job offer) is severe. See the full chain of custody for details.
In the event of a positive result
In the event of a confirmed positive with no medical explanation: the offer of employment can be withdrawn. This is not a dismissal, as the employment was never completed. The candidate should be informed factually and without details that risk leaking to other parties. The right to appeal and the right to have their personal data handled in accordance with the GDPR remain.
Confidentiality and GDPR
Results are stored in line with the recruitment procedure's normal deletion schedule – often 6 months after the recruitment has been completed, or in line with a defined purpose. Results are shared only with the hiring manager + HR.
Cost
A rapid test + laboratory verification usually costs around SEK 600–1,200 per candidate depending on the panel. Count it as part of the recruitment cost – cheaper than hiring someone who does not measure up.
