Are there standardised dosing guidelines for cannabis in AS? 

When it comes to medical cannabis dosage for ankylosing spondylitis, the reality is that no universal standard exists yet. Most healthcare professionals work within general frameworks, adapting based on the patient’s symptoms, cannabis tolerance, and treatment goals. Instead of rigid dosing, flexibility and responsiveness are central to achieving optimal relief. 

Current guidelines focus more on principles than numbers. Doctors usually recommend starting with low THC and gradually increasing only if needed. CBD-rich products are often used during the day, with THC introduced at night to assist with sleep. As each patient responds differently, dose adjustment becomes a critical part of care. 

Guidance for Finding the Right Dose 

To help patients navigate this variability, here are some key principles behind existing standard guidelines: 

Start low and increase slowly 

Initial doses often begin at 2.5 mg THC or 5–10 mg CBD, especially for new users. 

Prioritise consistency 

Stick with one method of delivery and track symptoms before making changes. 

Assess and adjust regularly 

Dose adjustment may be needed weekly, based on flare patterns and side effects. 

Match the product to the symptom 

CBD may help with stiffness and inflammation, while THC can support relaxation and pain relief.
