Cannabis and Safeguarding: Prescribing Safely for Vulnerable Patients

Safeguarding Obligations in Cannabis Prescribing

• UK law and GMC guidance require prescribers to consider safeguarding in all clinical interactions
• Vulnerable adults and children in the patient’s household may be indirectly affected by cannabis prescribing decisions
• Safeguarding does not prohibit cannabis prescribing — it requires that prescribing decisions are made with vulnerability awareness
• Prescribers must have access to named safeguarding leads and know the referral pathways in their organisation

Safeguarding is a dimension of cannabis prescribing that is frequently overlooked in the focus on pharmacology and clinical outcomes. Yet the prescribing of a controlled drug into a household where vulnerable individuals — children, adults at risk, or individuals with substance use disorders — are present creates specific safeguarding responsibilities. Clinicians must be confident in their ability to assess and respond to safeguarding concerns as part of their professional practice.

Identifying Vulnerable Patients in Cannabis Practice

• Adults with mental health conditions who may lack capacity at certain points during their illness
• Patients with a history of trauma, abuse, or exploitation that may intersect with substance use
• Young adults (18–25) in whom cannabis may have greater neurodevelopmental impact
• Patients in households with children, where secure storage and accidental access must be assessed

During the IMC and at all follow-up appointments, prescribers should proactively screen for vulnerability indicators. A question as simple as “Does anyone else live with you who might be affected by your medication?” can open the conversation. Patients should be assessed for cognitive capacity to manage their prescription safely, and where doubt exists, a formal mental capacity assessment should be arranged.

Controlled Drug Security: A Safeguarding Imperative

• Cannabis prescriptions must be stored securely in the patient’s home — ideally in a locked cabinet
• Accidental ingestion of cannabis by children is a recognised medical emergency requiring urgent hospital assessment
• Patients must be counselled on safe storage at every dispensing encounter
• Prescribers should document that safe storage advice has been given, and review compliance at follow-up

The prescription of any Schedule 2 controlled drug creates a responsibility to ensure that it is stored safely. Cannabis flower and oil preparations can be particularly attractive to children and young people due to their appearance and smell. A locked medicine cabinet is a proportionate and reasonable requirement, and prescribers who document that they have discussed this at initiation are in a stronger position if an accidental ingestion incident occurs.

Responding to Safeguarding Concerns in Clinical Practice

• If a patient discloses domestic abuse, immediately refer to MARAC and social services as appropriate
• Children at risk of harm from cannabis exposure in the home must be referred to children’s services under Section 47 procedures
• Do not allow safeguarding concerns to inhibit referral — the patient’s immediate medical needs can be addressed alongside a safeguarding referral
• Document all safeguarding decisions, including decisions not to refer and the reasoning behind them

Safeguarding referrals can feel disproportionate or disruptive, but the threshold for referral should be low when children or adults at risk are involved. The legal principle that the welfare of the child is paramount applies regardless of the clinical context, and a prescriber who becomes aware of a safeguarding risk and fails to act may face serious professional consequences. Familiarity with local safeguarding policies and regular safeguarding training are essential for all clinicians working in cannabis medicine.
