Yes, you can work while being treated with medical cannabis. What matters is that you can do your job safely. There is no general duty to tell your employer about your diagnosis or medicines. In safety-critical jobs, however, special duties of care apply.
This article explains the situation in general terms. For specific employment law questions, a specialist employment lawyer (Fachanwalt für Arbeitsrecht) can help.
What does occupational safety require?
Under the German accident prevention regulation DGUV Regulation 1 (DGUV Vorschrift 1), employees must not put themselves into a state through alcohol, drugs or other intoxicating substances in which they could endanger themselves or others. This explicitly also applies to medicines. Employers must not deploy employees who are visibly unable to work safely.
For patients this means: the problem is not the prescription, but possible impairment. If you are tired, drowsy or unable to concentrate, you should not carry out dangerous work.
Do I have to tell my employer about medical cannabis?
In principle, no. Health data are specially protected, and employers may not ask about diagnoses. It can be different if your job is safety-critical and your performance could be impaired, for example when driving, operating machines, where there is a risk of falling or in passenger transport.
A good route then is the company doctor (Betriebsarzt or Betriebsärztin): they are bound by medical confidentiality and only tell the employer whether there are health concerns about a particular job, not the diagnosis.
Can my employer ban cannabis at work?
Employers may ban the use of recreational cannabis at work, by instruction or by a works agreement (Betriebsvereinbarung), on which a works council has a say. An employer cannot impose a blanket ban on taking a medicine prescribed by a doctor. Restrictions must follow from occupational safety and be proportionate; with chronic illnesses, protection against discrimination under the General Equal Treatment Act (AGG) can also play a role. If you would need to inhale during working hours, clarify in advance where and when that is possible, ideally through the company doctor.
Drug tests at work
As a rule, testing is not allowed without consent. For particularly dangerous jobs, tests can be regulated in employment contracts or works agreements. Important: THC often remains detectable in urine for days to weeks, so a positive result says nothing about current impairment. More in How long does THC stay in your system?.
If you have a prescription, you can use your documents to show the reason for a positive result, see Cannabis patient ID.
Practical tips
During the titration phase and after dose changes, do not carry out safety-critical work until you know how the medicine affects you. Plan the times you take it with your doctor so that they fit your working day. On the way to work, the rules for road traffic apply, see Driving with a cannabis prescription.
Frequently asked questions
Can my employer ask whether I take cannabis?
In principle, an employer may not ask about diagnoses. In safety-critical jobs, however, you may be obliged to report circumstances that affect safe working, and an examination by the company doctor may be necessary.
Can I be dismissed because of medical cannabis?
The prescription alone is not a reason for dismissal. What matters is occupational safety and performance in the individual case. If there are specific problems, a specialist employment lawyer can help.
Can I inhale at work?
That depends on the rules at your workplace and on your job. Clarify it in advance and never work impaired in dangerous areas.
Do I have to agree to a drug test?
As a rule, no. For dangerous jobs, tests can be regulated by contract or works agreement, and refusing there can mean you are not deployed for that job.
