Like any medication, cannabis can cause side effects, including dizziness, dry mouth, fatigue, and appetite changes. Our medical team closely monitors each patient and adjusts dosages as needed to minimize unwanted effects.
At Doctor Herb Medical, the consultation includes a comprehensive medical history review, a discussion of your symptoms, and an assessment to determine if medical cannabis could benefit you. Our specialists will guide you through the process and create a personalised treatment plan.

The NHS currently prescribes medical cannabis only for a few severe conditions, such as certain types of epilepsy, muscle spasticity in multiple sclerosis (MS), and nausea/vomiting caused by chemotherapy, when other treatments have failed.
However, private medical cannabis clinics like Doctor Herb and Dr Green offer prescriptions for a broader range of conditions on a case-by-case basis. If you have a diagnosis for a different illness or condition, you may still be eligible for treatment.

• It is stored in its original packaging with the pharmacy label intact.
• You carry proof of your prescription, such as a Doctor Herb Medical Cannabis Prescription, to confirm your legal right to possess and consume it.

Our extensive selection includes over 200 premium cannabis strains, backed by a seed bank with more than 2,000 variations.

The time it takes for medical cannabis to take effect depends on several factors, including the type of product, method of use, personal tolerance, and metabolism.
• Inhalation (vaporising flower or oil) → Effects begin within 5–10 minutes and last 2–4 hours.
• Sublingual (oil under the tongue) → Bypasses digestion for faster absorption; effects start within 10–15 minutes and last 3–4 hours.
• Oral (capsules or swallowed oil) → Must pass through digestion and the liver; effects take up to 2 hours but last 4–6 hours.
• Topical (creams, patches, or oils applied to the skin) → Effects may take up to 90 minutes but can provide targeted relief for up to 12 hours.
Your dosage will be carefully determined by your Dr Herb and Dr Green prescribing specialist, who will monitor your progress and adjust your treatment plan as needed.
Since medical cannabis dosages are highly individual, there is no universal standard. However, you can feel confident that your prescription will be personalised to your needs and professionally managed.
Yes. If you require assistance with your medication, a carer, support worker, or family member can help administer it.
We can also provide documentation and guidance to support the administration of your medication. However, be aware that some care facilities or residential areas may have specific policies restricting medical cannabis use.
If you experience any side effects or wish to change your medication, you can contact our Patient Advisor Team at info@doctorherb.co.uk at any time.
Medical cannabis has a strong safety profile, and most patients can reduce or stop usage without complications. However, it’s always best to consult your prescribing doctor before making any changes. Your doctor can provide personalised advice on safely discontinuing or adjusting your medication.
Costs, Availability & Delivery
The NHS only prescribes medical cannabis for a very limited number of conditions, including two rare forms of epilepsy, nausea and vomiting due to cancer treatment, and muscle spasticity caused by multiple sclerosis (MS).

Driving and Travelling
The Cannabis Industry Council, the UK’s leading cannabis advocacy group, provides the following guidance:
Patients prescribed medical cannabis in the UK can drive as long as they meet the following conditions:
• They are not impaired while driving.
• Their cannabis medication is legally prescribed, and they can provide proof of this.
• They follow the dosage and usage instructions from their specialist consultant and the medication’s manufacturer or distributor.
Patients who meet these criteria may have a statutory medical defence if they are tested for THC levels exceeding 2μg/L in their blood. This legal defence can help prevent unnecessary blood tests, arrests, or prosecutions.
By following the guidelines outlined in this leaflet, patients can strengthen their legal defence and avoid legal complications related to driving with medical cannabis.
Do Not Drive If You Feel Impaired
• It is illegal to drive while impaired by any substance, including prescribed medication.
• Patients must assess their fitness to drive each time before getting behind the wheel.
• Avoid driving if you experience drowsiness, dizziness, slow reaction times, or visual disturbances.
• Be cautious when starting, increasing, or reducing your cannabis medication dosage, as this can increase the risk of impairment.
• Certain other medications (prescribed or over-the-counter) may interact with cannabis and impact driving ability.
• If you have an underlying health condition that could increase the side effects of your medication, take extra care.
• Combining alcohol with cannabis or other impairing substances greatly increases accident risks.
• If a patient is impaired, their legal defence is not valid.
Follow Your Specialist’s Advice & Medication Guidelines
• Always adhere to the dosage and instructions given by your specialist.
• Consider any warnings about interactions with other medications or substances.
• Read and follow the manufacturer’s guidance on safe usage.
Carry Evidence of Your Prescription
To avoid complications if stopped by the police, patients should always carry:
• A physical or digital copy of their most recent prescription.
• Photo ID (e.g., driver’s licence).
• A letter from their prescribing specialist (if possible).
• Medication in its original packaging, showing their name and prescription details.
What to Do If Stopped by the Police
• Remain calm, polite, and cooperative.
• You are not required to disclose your medical cannabis use unless the police suspect you are impaired.
• If questioned, state clearly that you have a legal prescription and provide your supporting documents.
• If asked to take a roadside THC test, politely inform them that you have a medical exemption and that preliminary tests are designed to detect illicit drugs.
• If necessary, show the police the QR code on your Releaf medical cannabis card, which links to the official guidance.
• If they insist on a swab, it is usually best to comply and remain cooperative.
• If requested to take an impairment test, comply, as refusing can lead to a separate offence.
• If arrested, wait for a lawyer before answering any questions. Ensure they understand your medical defence.
Medical cannabis has been legal in the UK since 1 November 2018. However, employers still have the right to enforce their own drug policies.
• If your workplace has a zero-tolerance policy, you may face disciplinary action if you test positive for THC.
• Cannabis-based medicinal products (CBMPs) containing THC are detectable in drug tests.
• If you are concerned about workplace testing, consider discussing your prescription with your employer or HR department in advance.
This depends on your destination country.
• Within the UK, you are legally permitted to travel with your prescribed medical cannabis.
• Some other countries allow entry with a valid prescription, while others do not recognise medical cannabis as legal.
• Always research the specific laws and regulations of your destination before travelling.
If you need to travel with your prescription, follow these steps:
1. Request a travel letter from us detailing your medical condition and prescription needs. Contact our team for patient advise at info@doctorherb.co.uk to obtain one.
2. Keep your prescription in its original packaging, showing your name and prescription details.
3. Carry a physical copy of your prescription along with your travel letter.
