Understanding psoriatic arthritis

Psoriatic arthritis is an inflammatory arthritis that develops in some people with the skin condition psoriasis. Up to about 1 in 3 people with psoriasis eventually develops it, and it can affect the joints, the spine and the places where tendons attach to bone.

It can cause swollen, painful joints and fingers, back pain, fatigue and nail changes that make daily tasks harder. Treatment usually includes anti-inflammatory medicines, methotrexate and biologic or targeted drugs that help control both skin and joint disease.

Symptoms patients hope to ease

  • Joint pain and swelling
  • Morning stiffness
  • Pain where tendons attach, such as the heel
  • Poor sleep because of pain
  • Fatigue
  • Itchy, uncomfortable skin

Does psoriatic arthritis qualify in your state?

What the research says

Moderate evidence. Joint pain falls under the chronic pain evidence.

  • The 2017 National Academies review found substantial evidence that cannabis can modestly reduce chronic pain in adults, though few studies focused on psoriatic arthritis.
  • A randomized trial of oral CBD in people with hand osteoarthritis and psoriatic arthritis found no clear pain benefit over placebo.
  • Lab studies suggest cannabinoids can affect skin cells and inflammation, but this has not been shown to improve psoriasis or joint damage in people.
  • Patient surveys show many people with psoriatic arthritis try cannabis for pain and sleep, but surveys cannot prove it works.

How doctors approach psoriatic arthritis

  1. Doctors often consider an oral product or tincture in the evening for joint pain and sleep.

  2. Topicals are sometimes tried for sore joints, but they should not be applied to broken or inflamed skin without checking with your dermatologist.

  3. A balanced CBD and THC product is a common starting point, since CBD alone did not reduce pain in a trial.

  4. Starting low and going slow helps limit side effects while you keep up your prescribed treatment.

Risks and precautions

  • Cannabis does not stop joint damage, so keep taking methotrexate, biologics or other prescribed treatment.
  • Methotrexate and CBD can both affect the liver, so your doctor may want to check your liver tests more often.
  • Smoking can worsen psoriasis and harm the lungs, especially if biologics raise your infection risk.
  • Psoriatic arthritis raises the risk of heart disease, and THC can raise heart rate.
  • Tell your rheumatologist and dermatologist about any cannabis use.
  • Not recommended during pregnancy or breastfeeding, and never drive while impaired.

What to bring to your evaluation

  • A psoriatic arthritis diagnosis from a rheumatologist.

  • Imaging or lab results if you have them.

  • A list of treatments tried, including NSAIDs, methotrexate and biologics, and how well they worked.

  • Notes on joint pain, fatigue and how symptoms affect your daily life.

  • A government photo ID and proof that you live in your state.

Psoriatic arthritis: 9 common questions

Does psoriatic arthritis qualify for a medical marijuana card?

Yes, in many places. 1 state program name psoriatic arthritis on the official list, and 14 more let the certifying provider decide. Either way, a provider licensed in your state has to evaluate you and agree that cannabis is appropriate.

Which states list psoriatic arthritis as a qualifying condition?

As of our latest check of each state's official list: Connecticut. Providers can also certify it in Alaska, California, Colorado, Delaware, Florida, Hawaii, Louisiana, Maine and 6 more, which don't use a fixed list. Lists change, so confirm on your state's page before you apply.

Can I get certified for psoriatic arthritis online?

Yes, in 12 of those states — including Connecticut, California, Delaware, Hawaii, Louisiana and 7 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 help psoriatic arthritis pain?

Cannabis has modest evidence for chronic pain in general, and some people with psoriatic arthritis report relief. A trial of CBD alone did not reduce pain compared with placebo. If you try cannabis, track your pain and sleep and review them with your doctor.

Can I use cannabis with methotrexate?

Both methotrexate and CBD can affect the liver. Using them together may need closer monitoring of liver tests. Avoid alcohol as well, and tell your rheumatologist before starting.

Can cannabis help my psoriasis?

Lab studies are interesting, but there is no good evidence that cannabis clears psoriasis in people. Smoking is linked with worse psoriasis. Keep working with your dermatologist on proven treatments.

Is CBD or THC better for psoriatic arthritis?

A trial of CBD alone did not show a clear pain benefit. Most pain evidence comes from products that include THC. A balanced product used in the evening is a common starting point.

Can I use cannabis with my biologic?

There is no known direct interaction between cannabis and most biologic drugs. Smoking is the main concern because biologics can increase infection risk. Choose non-smoked forms and let your rheumatologist know.

Can I use a cannabis topical on my psoriasis patches?

There is little evidence that cannabis topicals help psoriasis, and some products contain fragrances or alcohol that can irritate skin. Test a small area first and avoid broken skin. Ask your dermatologist before using it on plaques.
