Kidney stones (also known as renal calculi or urolithiasis) are masses of minerals and salt that form in your kidneys. They sometimes originate in the ureters, bladder, and urethra, reports Healthline . Kidney stones are known for being incredibly painful for many sufferers. There are several treatments for kidney stones, including medications, tunnel surgery, and lithotripsy, which uses sound waves to break up calcium masses, all of which are “tailored according to the type of stone,” reports Healthline.
Many patients suffering from kidney stones have reported that medical cannabis eases their pain and nausea. A 2017 study from the American Journal of Physiology-Renal Physiology details exactly how medical cannabis can ease kidney diseases, including stones. “The two different types of receptors (CB1 and CB2) that are activated by the pharmacologically active ingredients of cannabis are found in numerous tissues, including the kidneys,” according to the medical journal.
Causes, Symptoms & Treatment of Kidney Stones
When crystal-forming agents, including calcium, oxalate, and uric acid are not diluted enough in the urine, kidney stones develop, reports the Mayo Clinic . There are four types of kidney stones: calcium, struvite, uric acid, and cystine. As noted, passing kidney stones brings on severe pain, especially in the side and in the back (below the ribs).
Furthermore, “experimental studies suggest that stimulation of these receptors using pharmacologic agents or their naturally occurring ligands could have both deleterious and beneficial effects on the kidneys, depending on receptor distribution, type of renal insult, or the timing of the activation during acute or chronic states of kidney injury.”
A 2009 report out of the Journal of Pharmacology and Experimental Therapeutics explored if a cannabinoid could treat toxicity in the kidneys experienced by patients on cisplatin chemotherapy. The researchers found that cannabidiol was associated with reduction in inflammation, reduced cell death in the kidneys, and improved renal function in mice. The authors conclude that, “our results suggest that the nonpsychoactive cannabinoid CBD may be of significant therapeutic benefits against the renal complications of cisplatin chemotherapy by attenuating oxidative/nitrosative stress and cell death.”
The WHO adds that many open label and clinical trials have also found that this hemp plant cannabinoid “it is generally well tolerated, with a good safety profile.”
Research conducted in this area confirms CBD’s positive impact on kidney stone pain and overall kidney health.
In the end, if you’re concerned about whether CBD can help reduce your kidney stone pain safely and without unwanted side effects, you can always consult with medical professionals who are familiar with this cannabinoid and ask them for guidance when making the right decision for you.
Choosing CBD Product Type
CBD is one of hundreds of cannabinoids found within the hemp plant, of which tetrahydrocannabinol, or THC, is probably the most well-known.  Though, unlike THC, CBD does not create a psychoactive effect.
The National Institute on Drug Abuse (NIDA) shares that some of the health benefits provided by the cannabinoids found in medical cannabis and various CBD products include reduced inflammation and individuals having fewer seizures. 
Some of the options in this area include CBD oil and hemp oil, tinctures, sprays, and medical marijuana. It is important to note that medical marijuana also contains THC, so this is something to keep in mind if you want a product that does not offer a psychoactive effect.
Like with any other health supplement, proper dosing is important when it comes to safe and effective pain management for kidney stones.
