In this article, we look at what cholesterol is, the problems associated with statins, and research which on CBD for high cholesterol. Does cannabis affect cholesterol levels for better or worse? We take a look at the current research on this complex subject matter.
Can CBD Oil Lower Cholesterol Levels? [Exploring the FACTS]
According to the CDC, about 37% of Americans are living with elevated cholesterol; a condition that potentially doubles the risk of developing cardiovascular disease. Worryingly, only 55% of adults who need medicine to treat this issue are using it. The problem with detecting high cholesterol is that it’s symptomless; you could have the condition without even realizing it.
If a doctor diagnoses you with high cholesterol, it’s likely they will recommend a medication known as a statin. Statins can help lower the risk of things like heart attack and stroke by over 30%.
However, there are a list of adverse side effects that come along with most prescription statins. For example, patients with high cholesterol that take statins may experience migraines, trouble sleeping, drowsiness, dizziness, nausea, and gastrointestinal issues, just to name a few. Statins can also increase the likelihood of developing neuropathy, loss of memory, and even type-2 diabetes.
CBD oil for lowering cholesterol; is there any merit to the discussion?
Given the popularity of CBD oil in recent years, the discussion of using CBD oil to lower cholesterol has been brought up. But is there any clinical proof of CBD having an effect on cholesterol levels?
In this article, we look at what cholesterol is and why you’re likely to have high cholesterol. We’ll also examine various problems associated with statins, and discuss relevant scientific research relating to cannabis, CBD, and cholesterol levels.
What Is Cholesterol?
Cholesterol is a lipid found in your body’s cells. Though it generally has a negative connotation given its link to heart disease, cholesterol is actually essential and serves many important functions. It influences the creation of hormones, the synthesis of vitamin D, and helps to digest food correctly.
Cholesterol categorizes into two types: Low-Density Lipoproteins (LDL, aka ‘bad’ cholesterol), and High-Density Lipoproteins (HDL, aka ‘good’ cholesterol).
HDL helps remove LDL deposits and limits the buildup of plaque that leads to things like heart attack and stroke. If LDL levels are too high, plaque accumulation inside blood vessels can cause arteries to harden and become narrower. Plaque buildup can cause arteries to become fully blocked. A blocked artery prevents blood from reaching vital organs and tissues. The result is a heart attack or stroke.
What Causes High Cholesterol?
Typically, your cholesterol level increases with age. There are a number of lifestyle choices that contribute to increased LDL cholesterol levels, such as smoking, being overweight, and eating too many saturated fats. Dietary culprits that typically lead to high cholesterol are dairy items, processed foods, and fatty red meats. A lack of physical activity can also negatively impact cholesterol levels. This is why many health experts suggest a minimum of 20 minutes of physical activity a day.
The Problem with Statins
The first thing any person with high cholesterol levels might want to do is take a long, hard look at their lifestyle. They may want to incorporate fish, lean meats, low-fat products, fruit, vegetables, and whole grains into their diet. As for smokers, most any health professional would recommend quitting in order to lower excessive cholesterol levels.
In terms of medication for lowering cholesterol, it is common for physicians to prescribe statins. Statins inhibit an enzyme that the liver needs to produce LDL cholesterol. They also slightly increase HDL levels, which can move ‘bad’ cholesterol from the arteries to the liver.
Millions of Americans are currently using statins, and health experts suggest that millions more need to be using them. For example, the American College of Cardiology issued a set of recommendations for statins suggesting over 26 million Americans should be using them.
There’s a problem with these recommendations…
According to these numbers, at least one-third of people aged 40-75 with no history of cardiovascular problems should be on statin medication. Since statistics on the effectiveness of statins vary, however, Dr. Rita Redberg of the University of California in San Francisco suggests using cholesterol calculating tools – like the Framingham Calculator – to estimate personal cardiovascular risk.
Also, a realistic concern with statin use is the range of adverse side effects that they produce. Statins can cause things like liver damage and rhabdomyolysis – a condition that damages muscle cells. Further concerns include an increased risk of type 2 diabetes, increased blood sugar, and memory problems. That’s a lot of risk for a drug that may not help you in the long run.
Is CBD a Better Alternative for Lowering Cholesterol?
To put it bluntly, there is no clinical evidence on the use of CBD to lower cholesterol levels. No one should suggest or recommend that CBD can function in place of statins, or even in place of a lifestyle change.
That said, one study does discuss a potential relationship between cannabidiol use and “cholesterol metabolism-related genes.” The study, which appears in a 2011 edition of Cellular and Molecular Neurobiology, suggests that “CBD treatment modulates cholesterol homeostasis in microglial cells.”
Does this mean you can use CBD to help lower your cholesterol?
Not quite. While the findings of this particular study are intriguing, the results have no clinical bearing on the use of CBD for cholesterol level management.
A separate 2017 study in Cannabis and Cannabinoid Research also discusses the effect of CBD use on cholesterol. The study claims that CBD “increased cholesterol levels in WT [wild-type] mice, but not in CBD-treated transgenic [laboratory-bred] mice.” Researchers state that the lack of effect on cholesterol in the transgenic mice was likely due to “already-elevated cholesterol [levels] in the transgenic mice.”
Interestingly, later in the study researchers discuss the potential benefits of cannabidiol on hyperglycemia. In obese mice, it was observed that a four-week CBD treatment of 3 mg per kg of body weight “increased HDL-C concentration by 55% and reduced total cholesterol levels by more than 25%.”
Again, although this research is very interesting, it has no bearing on the practical use of CBD oil for lowering cholesterol levels. While there may indeed be a physiological relationship between the two, more research is needed.
Final Thoughts on CBD Oil for Reducing LDL Cholesterol
All in all, there is no explicit clinical evidence that CBD oil (or any other CBD product) can help reduce cholesterol levels. Many full-spectrum CBD oils contain healthy omega acids, which may help reduce the likelihood of cardiovascular disease. Again, however, this does not denote that CBD has any specific relationship with blood cholesterol levels.
Remember, however, that research into CBD is still very much in its infancy. There may be additional physiological properties of CBD that relate to cardiovascular health, but for now, little is known on the topic. As research improves, we are likely to witness some exciting discoveries in the future.
Does Cannabis Affect Your Cholesterol?

With cannabis use becoming more commonplace, some health-conscious consumers have begun wondering how it may affect cholesterol levels.
As is often the case, there exists sparse clinical research on the subject. However, early studies show that cannabinoids, especially CBD, can indeed impact cholesterol in some circumstances.
So, does cannabis affect cholesterol for better or worse? We explain all you need to know in this in-depth article. But first, let’s look at what cholesterol is and how it influences our health.
What Is Cholesterol?
Cholesterol is a lipoprotein, meaning it consists of both fat and protein molecules. It is a waxy substance and a key component of cell membranes. It has several crucial functions in the body, including acting as a precursor to sex hormones and vitamin D production.
Cholesterol is a lipoprotein that serves several critical functions in the body – including acting as a precursor to sex hormone and Vitmain D production.
The liver and intestines are major contributors to the endogenous production of cholesterol within the body. However, many foods also contain cholesterol, including meat, eggs, and dairy products. For this reason, people who eat these foods regularly may end up with high cholesterol – a significant risk factor for heart disease.
Cholesterol and Heart Health
Although some cholesterol is essential for good health, too much can be detrimental to an individual’s health. This is because excess cholesterol can combine with other substances and build up in the blood vessels.
These fatty build-ups are known as plaques, which can contribute to atherosclerosis, a narrowing, and hardening of the arteries.
Atherosclerosis causes inflammation in the blood vessels and can lead to coronary artery disease. Furthermore, if a plaque ruptures, blood clots can form and block the coronary artery. This prevents the heart from getting sufficient oxygen and can cause angina and heart attacks.
Atherosclerosis is also associated with other types of cardiovascular disease, including carotid artery disease, peripheral arterial disease, and strokes.
However, not all cholesterol is harmful. There are several different types, including:
- >Low-density lipoprotein (LDL): LDL is sometimes known as ‘bad cholesterol.’ It is the type of cholesterol that can form plaques and raise the risk of heart disease.
- Very low-density lipoprotein (VLDL): Like LDL, high levels of VLDL cholesterol have been associated with the development of plaque deposits on artery walls. However, VLDL is released into the bloodstream to supply body tissues with triglycerides. Triglycerides are another type of fat that could raise the risk of heart disease.
- High-density lipoprotein (HDL): Sometimes known as ‘good cholesterol,’ HDL transports LDL from the arteries to the liver for elimination.
What Is the Normal Cholesterol Level?
Target cholesterol levels vary depending on a person’s age and gender. The table below is a general guide:
Type of Cholesterol
Anyone Under 19
Males Age 20+
Females Age 20+
Non-HDL (including LDL, VLDL)
How to Lower Cholesterol
Some people have naturally higher cholesterol levels than others. Age, ethnicity, and genetics all play a role. However, many of the factors that influence cholesterol levels relate to lifestyle, and, therefore, individuals can alter them.
Some of the best ways to lower cholesterol include:
- Eating a healthy diet (minimal meat, dairy, chocolate, baked goods, fried, and processed foods)
- Engaging in regular physical exercise to maintain a healthy body weight and increase HDL
- Not smoking (smoking raises LDL levels and decreases HDL)
If an individual cannot control their cholesterol by making these lifestyle adjustments, their doctor may prescribe a cholesterol-lowering medication. Some of the most common cholesterol drugs are called ‘statins’, including:
Although these medications have demonstrated their efficacy in robust clinical trials, unpleasant side effects can still occur. Therefore, some people are looking for more natural alternatives and may be wondering whether cannabis or CBD could help.
So, how does cannabis affect cholesterol? Let’s take a look.
How Does Cannabis Affect Your Cholesterol?
There is currently little research on cannabis and cholesterol. However, there are a handful of studies that suggest it may have some effect.
A 2013 study for the Diabetes Care journal compared 30 cannabis smokers’ cholesterol levels with 30 control subjects. Cannabis use ranged from 3–30 joints per day (median 6) over 2–38 years (median 9.5).
The researchers found the cannabis smokers had lower HDL levels than the control subjects. However, there were no significant differences in total cholesterol, LDL, triglycerides, or free fatty acids. It is unclear whether the decrease in HDL levels was due to cannabis itself or the consumption method of smoking.
Furthermore, these results differ from those of a 2020 study that looked at CBD-containing hemp oil that illustrated significant improvements in HDL level among participants.
More Research on Cannabinoids and Cholesterol
A 2018 review for the Journal of the American Heart Association investigated the role of cannabinoids in cardiovascular disease. The paper primarily focused on delta-9 tetrahydrocannabinol (THC), the compound responsible for producing the typical cannabis high.
The authors found conflicting evidence regarding whether THC promotes or inhibits atherosclerosis.
It appears that by stimulating CB1 receptors in the endocannabinoid system, THC could increase oxidative stress and induce plaque formation. However, by stimulating CB2 receptors, it could reduce inflammation and inhibit LDL activity.
The review also mentions the CARDIA study, a project that followed cannabis users and non-users over 25 years. It found that cannabis users only had an increased risk of atherosclerosis if they smoked tobacco as well. The remaining studies in the review had inconclusive results, demonstrating the complex nature of cannabis chemistry.
Far more research is necessary before we fully understand the complex relationship between cannabis and cholesterol. However, more clear-cut evidence is emerging regarding the non-intoxicating cannabinoid cannabidiol (CBD).
CBD and Cholesterol
Recent research into CBD may help us to understand how cannabis affects cholesterol.
A 2011 study for Cellular and Molecular Neurobiology found that the compound influences cholesterol homeostasis, the process by which cells regulate cholesterol levels. This study illustrates how the endocannabinoid may play a role in cholesterol homeostasis.
A 2017 review for Cannabis and Cannabinoid Research investigated further. It found that CBD increased cholesterol levels in wild-type mice. However, it did not impact transgenic mice that already had high cholesterol. It also found that CBD increased HDL by 55% in obese mice while reducing total cholesterol by 25%.
Therefore, it appears that CBD has the potential to regulate cholesterol levels in the body. However, these are the results of laboratory studies, and it is impossible to say how they translate to humans.
Is It Safe to Take CBD Oil with High Cholesterol?
CBD is non-intoxicating, and most experts consider it to have a good safety profile. Therefore, it should be safe for people with high cholesterol to try.
However, there is a possible complication involving the use of CBD and cholesterol medication. CBD inhibits the activity of several liver enzymes. They include those responsible for metabolizing the cholesterol drugs simvastatin and atorvastatin.
Therefore, taking CBD oil with cholesterol medication could potentially produce adverse effects. Anyone considering doing so should consult a physician for further advice.
Does Cannabis Affect Your Cholesterol? Final Thoughts
There is insufficient evidence to conclusively say whether cannabis is good or bad for cholesterol.
While it appears that CBD could have a regulatory effect on cholesterol levels, human studies are currently lacking. And when it comes to THC, matters are even less clear-cut.
Some research studies suggest cannabis could raise the risk of atherosclerosis, while others state the opposite.
What we do know, though, is that smoking is a major risk factor for atherosclerosis. Therefore, it is advisable to avoid this consumption method, especially with tobacco.
Anyone worried about how cannabis use may be affecting their cholesterol levels should discuss their concerns with a knowledgeable physician.
