How your immune system and endocannabinoid system interact
The endocannabinoid system, when influenced by THC, seems to suppress your immune system. This isn’t always a bad thing. People with autoimmune conditions, organ transplant recipients, acne, or inflammation often use FDA-approved immunosuppressant medications to create this reaction on purpose.
When the immune system is attacking the body or acting in a way that elevates pain response, suppressing it prevents the situation from getting out of hand. It can help to mitigate painful symptoms of many conditions.
Cannabis hasn’t been approved in the United States for this purpose. Cannabis-based drugs like Sativex are approved throughout Europe and Canada to help manage the symptoms of autoimmune and neurodegenerative conditions like multiple sclerosis, but the method by which they work isn’t fully understood.
Recent research shows that cannabinoids have a profound effect on the lymphatic system as an immunomodulator. Both THC and CBD accumulate in the lymph cells of the intestines, preventing them from engaging.
For people with inflammatory bowel disease, this is exactly the effect they’re looking for. Most of their symptoms stem from their immune cells attacking their bowels instead of supporting them. Crippling them with cannabinoids holds this response back, providing relief.
The downside of cannabis’s anti-inflammatory power
All modern research seems to suggest that cannabis is an excellent anti-inflammatory, but there is such a thing as too much of a good thing. People who frequently use cannabis may have an imbalance of immune cells, favoring anti-inflammatory cells. It’s great to keep uncomfortable inflammation at bay, but when inflammation is managed to the detriment of white blood cells, the tradeoff no longer becomes beneficial.
Cannabis can’t target which cells it should and should not suppress. If your white blood cells are negatively impacted by cannabis, they won’t be able to properly perform their functions. They’ll be too lazy and impaired to kill the germs they’re supposed to kill. A common cold may be more difficult to overcome when your immune system is bogged down by cannabis.
Even though the link is established, there are still conflicting answers. Cannabis is often used as a treatment for managing symptoms in patients undergoing chemotherapy. Chemotherapy can eradicate cancer, but it also eradicates a lot of the things your body needs to function properly. Adding cannabis into the mix can further diminish the immune system, making some cancer patients more vulnerable than they already were.
Many patients and care providers find that the benefits of cannabis use are worth the risk, and cancer patients utilize extreme safety protocols to avoid exposure to germs while they’re in this immunocompromised state.
Patients with HIV and AIDS are another story. HIV and AIDS, especially when improperly managed, destroy the body’s immune system. The FDA has approved cannabis-based drugs for use in people with HIV and AIDS, which doesn’t seem to make sense. If the disease itself is diminishing the immune system, why add an immunosuppressant into the mix?
Cannabis can help to stimulate appetite in patients with HIV and AIDS who have a difficult time maintaining healthy body weight. The results were significant enough for the drug to be approved, and many patients who use cannabis are satisfied with the results.
Oddly enough, the detrimental immune effects attributed to cannabis aren’t usually present in people with HIV or AIDS. This may be a result of the effect that HIV and AIDS treatment drugs have on a patient’s immune system, although at this juncture, that only remains a theory. These patients are continuously fortifying and protecting their bodies with medications, which could potentially ward off some of weed’s immunosuppressant side effects.
The takeaway
Technically, weed can make your immune system weaker. For many people, that’s its selling point. People who use cannabis medicinally are counting on the relief they experience from the immunosuppressive effect of their cannabis, and some people report that it reduces the extent to which they feel pain.
If you have a weak immune system, you shouldn’t use cannabis without talking to your doctor. If you have a healthy immune system, take good care of yourself. Feeding your body properly and exercising can help to support that immune system. If you choose to occasionally indulge in cannabis, don’t do it when you have a cold or if you’re around people who may be sick.
If you’re interested in the effects of weed on the immune system and your doctor agrees that you might benefit, order some weed. See how it makes you feel. If your immune system is underactive, it may be best to skip the joint when someone passes it to you.
