While some studies suggest that cannabis might influence ulcer development, more research is necessary to better understand the potential effects of different cannabinoids.

A 2023 research review found that while cannabis offers benefits like pain relief and anti-inflammatory effects, it may also contribute to ulcers and other adverse outcomes. Tetrahydrocannabinol (THC), in particular, can affect gut movement and acid production, potentially worsening existing stomach conditions.

On the other hand, some studies suggest cannabis could be beneficial for ulcer management. For example, a 2023 trialTrusted Source tested topical cannabidiol (CBD) for recurrent aphthous ulcers (canker sores).

The results showed that CBD helped reduce ulcer size and speed up healing without significant side effects, indicating it may be useful for certain ulcers. Research exploring the effects of CBD on stomach ulcers is necessary.

A 2024 study investigating the effects of medical cannabis on gastrointestinal symptoms for a year found that it helped relieve symptoms related to ulcerative conditions. However, participants reported side effects like increased appetite and fatigue, which might aggravate some stomach conditions.

Tetrahydrocannabinol (THC), the psychoactive compound in cannabis, can cause a temporary increase in blood pressure and heart rate shortly after consumption.

These effects may be more common in people with limited experience with cannabis use or in those who consume large amounts.

More research is necessary to better understand the potential effects of long-term or chronic cannabis use on blood pressure and heart health.

In a 2023 study, researchers analyzed cross-sectional data from the National Health and Nutrition Examination Survey (NHANES). They looked at five 2-year cycles between 2009 and 2018, representing 9,783 adults ages 35 to 59 years.

They didn’t find a significant link between cannabis use and increased blood pressure in middle-aged adults. However, results could differ across age groups and other factors.

A 2024 studyTrusted Source of 2016 to 2020 data from the Behavioral Risk Factor Surveillance Survey found cannabis use linked with a higher risk of heart attack and stroke in adults ages 18 to 74 years.

Daily users had a 25% higher risk of heart attack and a 42% higher risk of stroke than nonusers.

According to more recent research shared in a March 2025 press release, adults under 50 years old are more than 6 times more likely to experience a heart attack than nonusers. The research also noted increased risks of heart failure and stroke among cannabis users.

Cannabidiol (CBD), a nonpsychoactive component of cannabis, may have potential cardiovascular benefits, such as lowering blood pressure, but more research is necessary to confirm these effects.

It’s also important to consider the method of consumption. Smoking and vaping cannabis can introduce harmful substances that negatively affect blood pressure and heart health.

Overall, cannabis’s effects on blood pressure can vary, and while CBD might help lower blood pressure in some cases, THC may increase it, especially in the short term.

Health experts do not typically link cannabis with causing neuropathy, but its effects on nerve health can be complex. They may vary based on individual use, dosage, and consumption methods.

Smoking and vaping cannabis can introduce harmful chemicals into your body. This can negatively affect vascular health and potentially contribute to nerve damage over time.

Researchers commonly study cannabis for its potential to treat neuropathic pain. For example, a small 2024 study found that transdermal treatments significantly reduced pain and other symptoms in people with diabetic neuropathy.

While this interaction can provide pain relief and reduce inflammation, excessive THC use may sometimes lead to side effects, such as altered sensory processing. These side effects may feel similar to nerve discomfort. However, these effects are temporary and reversible.

Some research suggests that cannabidiol (CBD), a nonpsychoactive component of cannabis. It may have neuroprotective qualities that could help prevent or reduce nerve damage in conditions like neuropathy.

While these studies highlight the potential benefits of cannabis in treating various forms of neuropathy, it’s important to note that research is ongoing. It’s a good idea to consult with a healthcare professional if you’re considering cannabis use, especially if you have concerns about your nerve health.
