Mixed connective tissue disease is a rare and complex mix of various rheumatic or inflammatory tissue conditions. This includes lupus, scleroderma, and myositis, and symptoms similar to those associated with rheumatoid arthritis are common.
MCTD only affects about 5 in every 100,000 people, with current research showing that 87% of those are female. The number of cases of MCTD may be on the rise.
What symptoms does mixed connective tissue disease cause?
MCTD is an overlap of conditions, with many showing similar symptoms. Any of these symptoms should prompt you to seek medical attention, particularly where they persist for several days.

Can medical cannabis treatment help with my mixed connective tissue disease symptoms?
Many people may find that taking THC or CBD for mixed connective tissue disease symptoms offers therapeutic effects. Treatments involving cannabis overlap connective tissue disease treatments from other sources, in many cases. It’s common to have a treatment plan that involves multiple therapies and medications, to help manage the complex and changing symptoms of MCTD.
Patient stories suggest that medical cannabis may offer therapeutic benefits for pain, sleeplessness, and coping with the mental load of complex, chronic illness. One patient said:
“I found that my medical cannabis oil really does help. In lots of ways. My sleep is better. It hasn’t been a monumental change, but definitely better. It’s better quality sleep, even if it’s still quite short some nights. More than that, I’m just dealing with life better than I have been in a long time.”
How does the endocannabinoid system relate to mixed connective tissue disease?
One of the reasons alternative treatments for mixed connective tissue disease include medical cannabis is because of cannabis’s impact on the endocannabinoid system. When in homeostasis, your internal systems are considered to be in balance, and a healthy endocannabinoid system contributes to this.
The endocannabinoid system is directly linked to the activity of the immune system, which is considered a major factor in MCTD.
The cannabinoids in medical cannabis, including THC and CBD, may have a positive impact on the endocannabinoid system. When considering CBD MCTD patients might find that the administration of this cannabinoid helps them feel calmer, less anxious, and sleep better.

Can medical cannabis help with Raynaud's phenomenon in MCTD?
When it comes to medical cannabis Raynauds MCTD symptoms could be alleviated by the administration of this alternative treatment. Limited research has been done in this area.
However, evidence suggests that CBD for mixed connective tissue disease symptoms like Raynaud’s can be effective for reducing the stress and anxiety that may be one trigger for the distressing symptoms. The NHS states that relaxing is one of the primary ways to avoid the symptoms of Raynaud’s phenomenon, and medical cannabis can contribute to a more relaxed state of mind.
What does the research say about cannabis and connective tissue diseases?
A report in The Lancet examined the case of a young woman struggling daily with the pain of a complex connective tissue disorder. In this particular case, opioids had caused problems, including addiction. The report states that medical cannabis helped her manage her pain effectively for the first time in ten years.
Fibrosis is the thickening of skin and tissues, and is a key symptom of scleroderma, one of the overlapping conditions of MCTD. A 2021 review of research studies suggests that medical cannabis can help alleviate pain and inflammation, and could even slow the progression of fibrosis.
What forms of Releaf medical cannabis can be prescribed for mixed connective tissue disease?
There are many symptoms and conditions medical cannabis can be prescribed for, including symptoms associated with MCTD. Medical cannabis may be prescribed in a number of ways, including:
A clinician will work with you to figure out the best format and medical cannabis strains to support your treatment. Different strains offer a different balance of cannabinoids and terpenes.
THC for mixed connective tissue disorder may help with reduced pain and nausea, while CBD is more associated with relaxation and improved sleep. It’s important to note, though, that homeostasis, the improved state of balance within your endocannabinoid system, is best achieved with a blend of therapeutic compounds. Your clinician will ensure that your prescription offers the right balance to best alleviate your symptoms.
CBD and terpenes are some of the most commonly discussed compounds of medical cannabis. CBD for mixed connective tissue disorder may be taken as an oil or in a vaporiser, but will rarely offer the same holistic benefits as full-spectrum medical cannabis.
During your follow-up consultation, you can let your clinician know how you've responded to your treatment plan, so they can fine-tune your treatment as needed.

How does MCTD overlap with lupus, scleroderma, and myositis?
MCTD is an overlap of these conditions, with any combination of these and other connective tissue disorders considered MCTD. Some of these conditions have similar symptoms, such as joint pain and fatigue. Others have specific symptoms that may require tailored treatment, such as the skin thickening associated with scleroderma.
Can medical cannabis be prescribed alongside my immunosuppressants for MCTD?
Your Releaf clinician will carefully review any existing medications you’re taking, including both over-the-counter and prescription medications. They’ll let you know if it’s appropriate to take medical cannabis alongside your current treatment options.
