In the UK, medical cannabis has been legally available since 2018, yet many patients still face stigma and discrimination in the workplace. Employers may dismiss or penalise employees simply for using legally prescribed medication, even when it does not affect job performance.
This comprehensive guide explores the legal rights of employees with medical cannabis prescriptions, employer responsibilities under UK employment law, and what can be done to create a fair and inclusive workplace.
Medical cannabis was legalised in the UK in 2018, but access remains limited. Despite being legal since 2018, medical cannabis remains misunderstood by many employers and HR departments across the UK.
Medical cannabis is available on prescription, typically for chronic conditions including:
However, NHS prescriptions for medical cannabis are rare, and most patients obtain their medication privately through specialist clinics like Lyphe.
One major issue is that many employers still do not differentiate between medical cannabis and recreational use. This leads to stigma, misunderstandings, and even wrongful dismissals.
Key fact: Medical cannabis does not automatically impair an employee’s ability to work safely. Just like other prescribed medications, it depends on dosage, type, and individual response. Yet, some employers use drug testing policies that fail to distinguish between legal medical use and illegal use, which can result in unfair disciplinary actions.
In the UK, the Equality Act 2010 protects employees from discrimination due to a disability. Many medical cannabis patients qualify for protection under this law if their condition substantially impacts daily life.
Important: Employers cannot legally dismiss someone solely for having a medical cannabis prescription. Instead, they must make reasonable adjustments, such as:
However, some companies still treat medical cannabis use as misconduct, even without evidence of impairment. This creates significant problems because workplace drug tests detect THC metabolites, which remain in the system long after impairment has worn off.
This means an employee could test positive for cannabis days or weeks after using their prescribed medication, despite being completely unimpaired at work.
If you’re considering medical cannabis treatment, it’s important to understand your workplace rights before starting your prescription. Many patients find it helpful to check their eligibility for treatment early in the process.
There have been several legal cases in the UK where employees successfully challenged unfair treatment for medical cannabis use:
Case Study 1: A warehouse worker was dismissed after failing a random drug test, despite disclosing his medical cannabis prescription. He later won a tribunal case arguing unfair dismissal under the Equality Act 2010.
Case Study 2: A progressive employer updated their policies after an employee disclosed medical cannabis use, ensuring testing focused on impairment rather than past consumption.
These cases highlight that employers need to recognise that legal medical cannabis use should not automatically lead to disciplinary action.
Employers have a legal and ethical duty to support employees who rely on prescribed medication, including medical cannabis.
Key steps employers should take:
Employees should feel comfortable discussing their medical needs without fear of discrimination or dismissal. Workplace safety remains important, but outdated policies can lead to unfair treatment of medical cannabis patients.
