Delta 8 Carts: Are They Safe for Kidney Health in 2024

Safe for Kidney Health


Delta-8-tetrahydrocannabinol (Delta 8 THC) is a cannabinoid found in cannabis that has gained popularity for its purported therapeutic benefits, including anxiety relief, pain management, and a milder psychoactive effect compared to its more famous cousin, Delta-9 THC. As Delta 8 products, particularly vape cartridges (Delta 8 carts), become more widely available, concerns about their safety have emerged, especially regarding their impact on kidney health. This article examines the potential risks and effects of Delta 8 on kidney health, considering existing research and expert opinions.

Understanding Delta 8 THC

Delta 8 THC is a minor cannabinoid occurring naturally in cannabis plants in small concentrations. It is chemically similar to Delta 9 THC but has a double bond on the eighth carbon chain rather than the ninth. This slight difference accounts for Delta 8’s lower potency and different effects on the body.

How Delta 8 THC Works

Delta 8 THC Carts interacts with the body’s endocannabinoid system (ECS), which plays a crucial role in maintaining homeostasis. It binds to the CB1 receptors in the brain and central nervous system and to a lesser extent to the CB2 receptors found in peripheral organs, including the kidneys. This interaction influences various physiological processes such as pain perception, mood, appetite, and immune response.

Potential Benefits of Delta 8 THC

Therapeutic Uses

  1. Pain Relief: Delta 8 THC has analgesic properties, making it useful for managing chronic pain conditions.
  2. Anti-Nausea: It has been shown to reduce nausea and vomiting, particularly in cancer patients undergoing chemotherapy.
  3. Appetite Stimulation: Delta 8 can stimulate appetite, which is beneficial for patients with eating disorders or cachexia.
  4. Anxiety Reduction: Users report that Delta 8 provides a calming effect without the intense high associated with Delta 9 THC.

Legal Status

Delta 8 THC occupies a gray area legally. It is often derived from hemp, making it federally legal under the 2018 Farm Bill, which legalized hemp and its derivatives. However, some states have specifically banned Delta 8 THC.

The Kidneys and Cannabinoids

Kidney Function Overview

The kidneys filter waste products from the blood, regulate fluid and electrolyte balance, and produce hormones that control blood pressure and red blood cell production. Given these essential functions, maintaining kidney health is critical.

Interaction of Cannabinoids with Kidneys

Cannabinoids can affect kidney function in several ways:

  1. Hemodynamics: Cannabinoids can alter renal blood flow and glomerular filtration rate (GFR).
  2. Inflammation and Fibrosis: Chronic use of cannabinoids might contribute to inflammation and fibrosis, affecting kidney structure and function.
  3. Electrolyte Balance: Cannabinoids can influence the balance of electrolytes, which is vital for kidney health.

Research on Delta 8 and Kidney Health

Current Studies

Research specific to Delta 8 THC and its effects on kidney health is limited. Most studies focus on Delta 9 THC and CBD, providing indirect insights.

Delta 9 THC and Kidneys

  1. Acute Kidney Injury (AKI): Some studies suggest a potential link between high doses of Delta 9 THC and acute kidney injury, particularly in vulnerable populations.
  2. Chronic Kidney Disease (CKD): Evidence is mixed regarding the impact of chronic cannabis use on kidney function. Some studies indicate potential protective effects, while others suggest possible harm due to inflammation and fibrosis.

CBD and Kidneys

CBD, another cannabinoid, has been studied more extensively. It appears to have anti-inflammatory and antioxidative properties that might protect the kidneys from damage. However, the impact of CBD is not directly transferable to Delta 8 due to their different pharmacological profiles.

Potential Risks of Delta 8 THC

Given the lack of specific research on Delta 8 THC, potential risks are inferred from related cannabinoids:

  1. Kidney Function Alteration: Like Delta 9, Delta 8 could potentially alter renal blood flow and GFR.
  2. Inflammation and Fibrosis: Chronic use might contribute to kidney inflammation and fibrosis.
  3. Toxicity from Contaminants: The unregulated market for Delta 8 carts raises concerns about product purity and the presence of harmful contaminants, which could adversely affect kidney health.

Expert Opinions

Medical Community View

Many healthcare professionals urge caution with Delta 8 THC use due to the lack of comprehensive research. They emphasize the importance of consulting with a healthcare provider before using Delta 8, especially for individuals with pre-existing kidney conditions.

Regulatory Perspective

Regulatory bodies like the FDA have issued warnings about the potential risks associated with Delta 8 products. They highlight issues related to product quality, mislabeling, and the potential presence of harmful chemicals.



While Delta 8 THC offers potential therapeutic benefits, its safety profile, particularly concerning kidney health, remains under-researched. The limited available data suggest that cannabinoids can influence kidney function and health, both positively and negatively. Given the crucial role of the kidneys in overall health, it is essential to approach Delta 8 use with caution.


  1. Consult Healthcare Providers: Before using Delta 8 carts, individuals, especially those with kidney issues, should consult healthcare professionals.
  2. Quality Assurance: Choose products from reputable sources that provide third-party testing to ensure purity and absence of contaminants.
  3. Monitor Health: Regular monitoring of kidney function through blood tests and other diagnostics is advisable for users of Delta 8 THC.
  4. Stay Informed: Keep abreast of new research and regulatory updates regarding Delta 8 THC and its health effects.

Final Thoughts

The safety of Delta 8 carts, particularly concerning kidney health, is not well established. While anecdotal reports and preliminary studies suggest potential benefits, the lack of rigorous research means that potential risks cannot be ruled out. As the popularity of Delta 8 THC continues to rise, it is crucial to prioritize safety and well-being through informed decisions and professional guidance.
