The Different Ways to Take Medical Cannabis
The route of administration profoundly affects onset time, duration, bioavailability and overall clinical effect. Choosing the right method for your condition and lifestyle is as important as choosing the right product.
Vaporised Flower
The most common form prescribed in UK clinics. Onset: 5-15 minutes. Duration: 2-4 hours. Bioavailability: 30-60%. Best for breakthrough pain, acute anxiety, nausea. Requires a medical vaporiser (£150-350).
Sublingual Oils and Sprays
Cannabis oil placed under the tongue. Onset: 15-45 minutes. Duration: 4-8 hours. Best for sustained all-day relief - chronic pain, anxiety, MS spasticity. Hold under tongue for 60-90 seconds before swallowing for maximum absorption.
Capsules
Swallowed, absorbed through gastrointestinal tract. Onset: 60-120 minutes. Duration: 6-10 hours. Best for consistent all-day background dosing. Taking with a fatty meal can double bioavailability - keep timing consistent.
Combining Methods
Many UK patients use oil for baseline control plus vaporised flower for breakthroughs - mirroring long-acting plus fast-acting opioid protocols. Common combinations:
- Oil (morning + evening) + flower (as needed): Most common for chronic pain
- CBD oil (daily) + low-THC flower (evening): Popular for anxiety with sleep disruption
- Oil only: Preferred for patients with respiratory concerns
