Weeding Through the Facts: Can Medical Marijuana Actually Thin Your Blood?

Weeding Medical Marijuana

In the US, medical professionals are beginning to support the use of medical marijuana for illnesses. It is now widely used to assist people with physically and mentally incapacitating conditions. 

Despite the fact that many US states have legalized marijuana for medical use with a valid medical marijuana card, cannabis has recently become more well-known as a blood thinner that can benefit people with heart problems. 

The use of blood thinners to keep their blood from clotting is necessary for about 3 million people in the US. Marijuana use as a possible blood thinner substitute has gained traction recently due to numerous new studies and trends. 

Because of the various compounds it contains, marijuana or cannabis is used as a blood thinner. Medical experts, however, are still hesitant to suggest it as a blood-thinning medication. 

This makes sense because further thorough research is still required to ascertain the precise mechanism by which cannabis thins the blood. In addition to the potential harm that medical cannabis can cause to a number of illnesses, there is also the concern that it may conflict with other prescriptions. This is due to the fact that cannabis alters how the body reacts to different drugs. Because of this, the majority of medical professionals do not support the use of medical marijuana as a medication.

Having said that, medical marijuana’s main disqualification as a blood thinner is its propensity to alter the way the body reacts to other drugs. Certain characteristics of cannabis influence how the body reacts to traditional blood thinners. 

What does blood thinning mean?

The term “blood thinner” does not always imply that the medicine thins your blood. Blood thinners are substances that have antiplatelet or anticoagulant properties. They can occasionally have antiplatelet and anticoagulant qualities. 

Heparin and warfarin are examples of anticoagulant medications that function by preventing blood clots from forming inside the body. 

They function by stopping the processes that result in clots or by dissolving clots that have already formed inside the body to stop them from getting bigger. 

The mechanism by which antiplatelet drugs, such as aspirin, prevent blood clotting is distinct. They function by stopping platelets, which are the type of cells that cause clots to form, from aggregating. Platelets adhering to one another is known as platelet aggregation. 

Thus, contrary to what its name implies, a blood thinner does not thin your blood. Instead, it functions by either inhibiting platelet aggregation or inhibiting and dismantling the processes involved in the formation of blood clots. Because blood clots can obstruct blood vessels, it is crucial to prevent their formation in the blood. Depending on which vessel the blood clot blocks when this occurs, it may result in potentially fatal circumstances like a heart attack or stroke. 

Heparin and warfarin are examples of anticoagulant medications that break down clots and stop any pre-existing clots from growing larger. 

Antiplatelet drugs, such as aspirin, stop blood platelets from adhering to one another and clumping together, which is what causes clots to form. Anyone can purchase aspirin as an over-the-counter medication.

What are the medical conditions treated with blood thinners?

Numerous medical conditions are treated with anticoagulant and antiplatelet medications. Blood clots can either cause or exacerbate these conditions. These conditions include, for instance:

  • Abnormal heart arrhythmias, such as atrial fibrillation
  • Congenital heart disorders
  • Ischemic heart disease
  • Certain chronic blood vessel diseases
  • Replacement of heart valve 

Surgery is another factor that raises the likelihood of clotting. For this reason, doctors advise patients to take blood-thinning drugs to avoid blood clots following surgery.

What are the risks associated with the use of blood thinners?

As with all medications, there are risks associated with using blood thinners. Blood thinners can be particularly dangerous in cases of bleeding because they function by preventing the formation of blood clots. Bleeding happens as a result of manipulation of the blood’s capacity to clot and to aggregate platelets. Anyone taking such medications runs the risk of experiencing hemorrhagic shock in the event of bleeding. 

Medical professionals routinely warn patients about the risks associated with using blood clotting medications when writing prescriptions for them. Patients are always advised to take these medications exactly as prescribed by their physician. 

Patients are made aware of the risks associated with using anticoagulant and antiplatelet drugs, particularly when they are taken in conjunction with specific foods, vitamins, alcoholic beverages, and other medications. 

For this reason, it is critical that you provide all relevant information to your healthcare providers regarding your medications, including information about foods, supplements, and way of life. This will assist your physician in assessing the degree of risk involved in your use of blood thinners. 

Blood thinner users need to have regular blood tests to monitor the effectiveness of their drugs and make sure their bodies are not designed to bleed excessively. 

Does marijuana have blood-thinning properties?

One frequently asked query is, “Is cannabis a blood thinner?” Although the precise mechanism underlying the effects of marijuana on blood clotting and blood thinners is still unknown, scientists are aware of some of these effects. The way that marijuana affects the body is by having an effect on platelet aggregation, which is required for blood clots to form. It therefore possesses antiplatelet qualities.

Because there are not enough reliable scientific studies or data to substantiate the claim that marijuana is a blood thinner, it is neither advised nor prescribed as one.

Before you begin to consider using medical marijuana to treat your health issue, we always advise you to speak with a medical marijuana doctor. A medical professional can advise you on how to use marijuana safely and will inform you of the state’s marijuana laws. 

Can Medicinal Cannabis Substitute Your Blood Thinners?

Further research on the safety and efficacy of marijuana is required before it can take the place of traditional blood thinners. Patients must obtain a doctor’s recommendation before switching from blood-thinning drugs to marijuana. These patients will also require careful observation for any complications by a qualified medical practitioner. 

Does marijuana thin your blood? is another question that many patients have. The short answer is in part, yes.

Because cannabis thins the blood, people who use it as a blood thinner should stay away from products that contain compounds found in marijuana. 

Medical professionals are primarily concerned because there aren’t many hard scientific studies that support the mechanism behind cannabis’s blood-thinning effects and how it interacts with other blood-thinning drugs. 

You must give your doctors all the information they require if you intend to use medical marijuana in place of your regular blood thinner. 

For those who are taking blood pressure medication, smoking marijuana may also have certain side effects. 

You should consult your physician if you are among those who are wondering, “Can you smoke on blood pressure medicine?”

You don’t need to be concerned about your medical professionals passing judgment on you because of the stigma attached to marijuana use. You should be okay as long as your doctor gives you all the information you require regarding marijuana use. 

Is it Safe to Combine Medicinal Marijuana with Blood Thinners?

Patients should consult their physicians if they intend to use marijuana. Medical marijuana may alter the body’s response to blood thinners. Therefore, patients who use marijuana in conjunction with blood thinners should always use caution.

Does CBD Oil Have Blood Thinning Effects?

CBD oil and cannabis work pretty much the same way. This indicates that it is a blood thinner due to certain characteristics. Despite coming from the hemp plant, CBD oil nevertheless has some blood-thinning properties. 

There have been some documented instances of CBD products impacting the physiological effects of blood thinners, including warfarin, ibuprofen, and naproxen, on the body. The body typically breaks down these medications over time. 

The effects of these medications on blood clotting may be prolonged by CBD oil because it may alter how long it takes the body to break them down. CBD achieves this by interfering with cytochrome P450, which prevents these medications from being metabolized in the liver. 

A class of enzymes called cytochrome P450 aids in the breakdown of medications in the blood. Blood thinner medications continue to rise in the body as a result of the interaction between these enzyme groups and CBD oil. The effects of these blood thinners were prolonged as a result. This can result in life-threatening internal bleeding and severe bleeding if left untreated.

Does THC Have Blood Thinning Properties?

One type of cannabinoid found in marijuana is tetrahydrocannabinol (THC). Studies in test tubes have demonstrated the anticoagulant properties of THC. Clinical research hasn’t been done on THC’s impact on human clotting, though. The potential side effects and interactions of THC’s anticoagulant properties with other medications are unknown.

How to Use Marijuana Safely While Taking Blood Thinners?

When blood thinners and marijuana are combined, bleeding complications may occur. Despite the fact that no documented cases of cannabis-related bleeding exist. Blood thinners’ prolonged effects may result in excessive bleeding if marijuana is used.

Why is there a dearth of understanding regarding the relationship between marijuana, hemp oil, and blood thinners?

The United States’ position on marijuana use as a drug is a major factor in the paucity of information regarding the complications associated with the interactions between hemp products, marijuana, and blood things drugs. Marijuana is classified by the US government as a schedule 1 drug. 

Schedule 1 substances are defined by the US government as substances having no therapeutic value. This makes it very difficult to conduct lawful studies and research on marijuana and its products. The marijuana data collected over the past ten years come from research conducted in other nations where marijuana use is legal. Despite a large body of research demonstrating positive effects, the US has not altered its position on marijuana use. The law pertaining to marijuana use is still in effect. 

In certain states of the United States, there have been some trends regarding the use of medical marijuana; ideally, research will be conducted in the country to support this use.


Even though there aren’t many studies on cannabis’s ability to thin blood in the US, many people still view medical marijuana as a plant with therapeutic benefits. It is not a question of if, but rather when marijuana will be accepted globally as a valuable treatment for a wide range of ailments.
