Are there any contraindications for cannabis use in AS patients? 

Author: Dr. Stefan Petrov, MBBS

It’s essential to understand cannabis contraindications for AS (ankylosing spondylitis) before starting treatment. While many benefit from medicinal use, not everyone is a suitable candidate. Knowing who should avoid marijuana can prevent complications and guide safer use. 

People with a history of certain mental health disorders, heart conditions, or sensitivity to cannabinoids may face greater risks. Likewise, cannabis and autoimmune risk is still being explored, particularly in patients with overlapping autoimmune conditions. Recognising health risks associated with AS weed use can help patients and clinicians make better informed decisions. This contraindication guide aims to highlight scenarios where cannabis use should be approached with caution. 

When to Reconsider or Delay Use 

History of psychosis or schizophrenia 

THC may worsen psychiatric symptoms in vulnerable individuals. 

Unstable cardiovascular conditions 

Cannabis can increase heart rate and blood pressure, which may pose a risk for some patients. 

Pregnancy or breastfeeding 

The effects on foetal and infant development are not well understood, so use is not recommended. 

Poor response to past cannabis use 

If you’ve had negative experiences with cannabis previously, consult a healthcare provider before resuming. 

Visit providers like LeafEase for personal consultations to evaluate whether cannabis is appropriate for your specific health profile.
