Understanding ankylosing spondylitis

Ankylosing spondylitis is a long-term inflammatory arthritis that mainly affects the joints of the spine and the sacroiliac joints where the spine meets the pelvis. It usually starts in the late teens to early forties, and estimates suggest it affects roughly 0.1 to 0.5 percent of US adults.

Many people live with deep low back pain and stiffness that is worst in the morning or after rest and eases with movement. Treatment usually combines daily exercise and physical therapy with anti-inflammatory medicines, and many people move on to biologic drugs such as TNF or IL-17 inhibitors when those are not enough.

Symptoms patients hope to ease

Inflammatory back and buttock pain
Morning stiffness that takes a long time to ease
Pain that wakes you in the second half of the night
Poor sleep and the tiredness that follows
Neck, hip and rib cage pain or stiffness
Muscle tension around stiff joints

What the research says

Moderate evidence. Covered by the chronic pain evidence in most cases; condition-specific trials are lacking.

There are no large clinical trials of medical cannabis specifically in ankylosing spondylitis.
The 2017 National Academies review found substantial evidence that cannabis can modestly reduce chronic pain in adults, which is the main reason people with this condition try it.
Lab and animal studies suggest cannabinoids can influence inflammation, but this has not been shown to slow spinal damage in people.
Patient surveys from rheumatology clinics report that some people use cannabis for pain and sleep, though surveys cannot prove it works.

How doctors approach ankylosing spondylitis

Doctors often suggest an oral product or tincture taken in the evening to help with night pain and morning stiffness.
A CBD-dominant or balanced CBD and THC product is a common starting point for people who want to stay clear-headed during the day.
Topical products are sometimes added for sore areas, though they do not reach the deep spinal joints well.
Your doctor will usually advise starting with a low dose and increasing slowly while you keep up your exercise program.

Risks and precautions

Cannabis does not replace biologic drugs or other treatments that control inflammation, so keep taking them as prescribed.
Smoking is a poor choice because this condition can limit chest expansion and biologic drugs can raise the risk of lung infections.
A fused or stiff spine fractures more easily, so dizziness or unsteadiness from THC that leads to a fall can be serious.
If you take a blood thinner such as warfarin, CBD can change how your body processes it, so your prescriber may need to check your levels more often.
Tell your rheumatologist about any cannabis use so it can be weighed alongside your other medicines.
Not recommended during pregnancy or breastfeeding, and never drive while impaired.

What to bring to your evaluation

A diagnosis from a rheumatologist, ideally with imaging of the sacroiliac joints or spine.
HLA-B27 or inflammatory marker results if you have them.
A list of treatments you have tried, including NSAIDs and any biologic drugs, and how well they worked.
Notes on how pain and stiffness affect your sleep, work and daily activity.
A government photo ID and proof that you live in your state.

Ankylosing spondylitis: 9 common questions

Does ankylosing spondylitis qualify for a medical marijuana card?

It can. No state lists ankylosing spondylitis by name, but 14 states let providers certify any condition they believe cannabis will help. Either way, a provider licensed in your state has to evaluate you and agree that cannabis is appropriate.

Which states list ankylosing spondylitis as a qualifying condition?

None list it by name. It can still be certified in Alaska, California, Colorado, Delaware, Florida, Hawaii, Louisiana, Maine and 6 more, where providers decide. Lists change, so confirm on your state's page before you apply.

Can I get certified for ankylosing spondylitis online?

Yes, in 11 of those states — including California, Delaware, Hawaii, Louisiana, Maine and 6 more — your first evaluation can happen by video with a provider licensed there. In 3 others, such as Alaska, Colorado and Florida, the first visit must be in person, and renewals can usually be done online.

Can cannabis slow down ankylosing spondylitis?

No study has shown that cannabis slows spinal fusion or changes the course of the disease. At best it may ease pain and help with sleep. Keep working with your rheumatologist on treatments that control inflammation, such as biologics and exercise.

Is CBD or THC better for ankylosing spondylitis pain?

There is no research comparing them in this condition. Many people start with CBD or a balanced product because it is less likely to cause a high, and add a little THC in the evening if pain disturbs sleep. Your certifying doctor can help you choose a starting point.

Can I use cannabis while taking a biologic like a TNF inhibitor?

There is no known direct interaction between cannabis and most biologic drugs. The bigger concern is smoking, which can irritate your lungs at a time when biologics already raise infection risk. Choose a non-smoked form and let your rheumatologist know what you are using.

Will cannabis help with morning stiffness?

Some people find that an evening dose of an oral product helps them sleep through the night and feel less stiff in the morning. Results vary, and there is no trial evidence for this specific effect. Morning stretching and movement remain the most reliable way to loosen up.

Can I take cannabis with my NSAID?

There is no well-known harmful interaction between cannabis and common NSAIDs like naproxen or ibuprofen. Some people find they need a little less NSAID, but do not change your dose without talking to your doctor. Watch for stomach upset if you use both.

How long does cannabis take to work for back pain?

Vaporized cannabis usually acts within minutes, while oral products and edibles can take one to two hours. Because oral effects arrive slowly, wait at least two hours before taking more. Keeping a simple pain diary for a few weeks will help you and your doctor judge whether it is helping.
