How Does Marijuana Affect Blood Pressure? Here’s What Science Says

The relationship between marijuana and high blood pressure is so complex that even the experts cannot conclude if our favorite herb is safe for people who have hypertension.

Some say that cannabis increases the risk of cardiac arrest in people already suffering from high blood pressure, while others claim there aren’t nearly enough cases to prove that.

Most of the studies I found while writing this article also have opposing conclusions.

The reason being is that they have mostly been conducted on animals and usually without including other factors that often cause hypertension.

However, according to seasoned weed vets and observational studies, cannabis first slightly increases your blood pressure and then lowers it.

But that’s not nearly good enough answer.

To find out the truth behind many claims concerning this question, I decided to go through every important study dealing with the effects of weed on blood pressure and then present my findings in this guide.

Also, I’ll be looking into experiences of real users, which I believe are of the utmost importance in cases like this one.

Let’s find out how weed affects blood pressure, once and for all.

What is high blood pressure (hypertension)?

What is high blood presure

Before we can dive into the effects of marijuana on blood pressure we first need to understand the difference between normal and high blood pressure.

When your heart beats, it pumps the blood through your arteries, forcing them to expand and contract.

The force with which the blood presses on the arteries is known as the blood pressure. Its function is essential, as it helps our body deliver oxygen and other nutrients to our organs.

When our heart pumps, it pushes the blood through our arteries, which causes the pressure inside them. This is known as a systolic pressure.

Between two heartbeats, at the moment when the heart rests, there is a pressure called diastolic.

In healthy individuals, the heart does not have to work excessively so the blood flow is smooth.

For most healthy adults, the normal blood pressure is between 100-130 millimeters systolic and between 60-80 diastolic.

However, if the arteries are narrower than usual, we come to a condition called high blood pressure, or hypertension.

High blood pressure is a long-term cardiovascular condition which occurs when the blood pressure in arteries is constantly elevated.

This usually happens if the arteries are clogged up, so the pressure rises and the heart has to work more. That’s also how arteries get damaged over a long stretch of time.

Hypertension affects about a third of adult Americans and around 7.7% of Canadians.

Unfortunately, the condition itself usually does not come with any symptoms.

Most of the time, patients discover they have high blood pressure during a regular screening.

Hypertension is not something that should be ignored. If left untreated, it can cause serious health problems.

If you are wondering what causes the increased blood pressure in the first place, you should know that even the experts haven’t fully answered that question.

As with many other conditions, there are certain things that can influence the development of this disorder. Genetics, smoking tobacco, drinking alcohol, obesity, bad diet and stress all play a role.

What science has to say about marijuana and hypertension?

Measuring blood pressure

As I’ve said, we barely have a few studies on the influence of cannabis on blood pressure, and they usually don’t analyze all the different factors, which would make the results conclusive.

But here is what I’ve found so far.

THC is not the best friend of hypertension?

The first study I’m going to reference is a study published in August 2017, conveniently named the “Effect of marijuana use on cardiovascular and cerebrovascular mortality”.

One of the most quoted studies on marijuana and high blood pressure, this paper suggests that regular cannabis users are three times more likely to die from hypertension.

But there is one huge problem with it:

It consists of participants who used cannabis “at least once in their life”, so we basically have no idea whether the subjects smoked every day or they just smoked once in high school, which leaves a lot of room on the table for misinterpretation.

It’s important to point out that the study was observational, meaning that the participants gave their feedback through follow up visits.

So, basically, there is no possible way to know for sure if cannabis itself had any role in causing hypertension.

There are a few studies that suggest that occasional users may experience a mild or moderate increase in heart rate, with a slight increase in blood pressure 10-15 minutes after consuming cannabis.

These studies claim that, after the initial increase, our blood pressure drops, leaving us sleepy and groggy (sounds familiar, right?).

Some marijuana consumers can also develop tolerance to uncomfortable side effects of pot just a few days or weeks after using the herb.

When it comes to more severe consequences of high blood pressure linked to cannabis use, we can only rely on CARDIA’s report, which followed more than 3.500 Americans over the course of 15 years.

The results might sound surprising at first:

No long-term connection was found between marijuana and cardiovascular diseases, such as heart attack and stroke.

However, the study also pointed out that:

“Although marijuana use was not independently associated with cardiovascular risk factors, it was associated with other unhealthy behaviors, such as high caloric diet, tobacco smoking, and other illicit drug use.”

Tip: take it easy on the food when the munchies come lurking.

A study done by Harvard Medical School pointed out this:

The risk of having a heart attack is increased five times during the first hour after smoking cannabis, but then drops 1.7 times during the next hour. The risk returns to normal after two hours.

At this point, it’s important to point out that many other everyday activities bring with them a much higher risk of heart attack, such as sex.

Fortunately, there have only been a few cases of people actually having a heart attack after smoking weed. As you may presume, it’s impossible to conclude if weed and its influence on blood pressure was the main culprit.

Can CBD lower blood pressure?

CBD blood pressure

The problem with the studies I found is that most of them are focused only on one cannabinoid in the whole cannabis plant — the psychoactive tetrahydrocannabinol (THC).

There are more than a 100 different cannabinoids as well as terpenes in the cannabis plant.

Today, we have hundreds of different strains on the market, each with different ratios of THC to CBD. Each with different medical effects.

Not to mention that there isn’t even one single research on how edibles might affect blood pressure.

That same THC has been linked to making some people anxious, sometimes even paranoid (but these are usually just short-term effects, which go away as soon as the high wears off).

Elevated heart rate always goes hand in hand with anxiety, therefore it’s almost expected to increase the blood pressure in some users.

On the other hand, the other popular cannabinoid, the one that’s stealing the spotlight lately, seems to have an opposite effect on blood pressure.

I’m talking, of course, about cannabidiol, or better known as CBD, famous for reducing all types of anxiety and inflammation.

So, as it turns out, according to a small study published in JCI Insight, a single dose of CBD lowers systolic blood pressure.

To be precise, CBD relaxes smooth muscle cells in the arteries, widening the blood vessels, providing a smoother blood flow and a lower blood pressure.

Best strains for people who suffer from high blood pressure

Weed heart

Smoking is one of the main causes of high blood pressure.

If you are suffering from hypertension you should probably avoid smoking altogether, as it’s most likely that it will cause your blood pressure to rise further.

While I was doing research for this article, I read some comments and threads on Reddit, and I found different opinions on smoking marijuana while suffering from hypertension.

Some patients smoke regularly and they say that weed keeps their BP in check.

Some patients, who used to smoke often, experienced a more normal blood pressure after quitting weed. But they also say that, during the period when their blood pressure was high, they were usually under a lot of stress and their diet wasn’t right.

So, we can’t blame it all on weed yet.

Thankfully, smoking is not the only cannabis consumption method.

Vaping and edibles (including oils) are all healthier alternatives to combusting a flower.

So, if you like weed and have been diagnosed with hypertension, my advice would be to:

Feel free to start with the 5 strains I listed below, little by little and monitor your blood pressure after using pot.

If you don’t feel your best with one particular strain, try a few more.

If your pressure rises after using weed, quit smoking altogether.

You can live without cannabis, trust me and you well-being should be your biggest priority at all times.

Purple Wreck

One of the most popular strains in the medical world, this thoroughbred indica is usually recommended for a variety of conditions.

Purple Wreck will give you a full body relaxation, helping the blood pressure drop down while eliminating stress at the same time. This strain won’t make you sleepy as most indica’s but it’s better you used it at night, as you close off your day.

Blue Dream

Also a very popular medical strain, Blue Dream will provide you with relaxation and a holistic balance of your entire system.

While it will calm you down, it’ll also relieve the tension in your blood vessels, which makes it a great tool for those suffering from hypertension.

Northern Lights

Although this strain has a very high THC content, hypertension patients have had a very good experience with it as a natural way to lower blood pressure.

Northern Lights will help your muscles relax, and you will likely experience a relaxation of all tissues, helping the blood flow through your arteries more smoothly.

Super Sour Diesel

Super Sour Diesel is a very potent strain, so take it easy with this one, as you would with any other strain rich in THC.

Provided you get the dosage right, it will help you leave the stress behind, which is also one of the main causes of hypertension.

Green Crack

Formerly known as “Cush”, Green Crack got its new name from Snoop Dogg — after he tried this potent sativa, he joyously renamed it because of the energetic kick it brings.

Because of its sativa dominance, Green Crack is much better suited for daytime use, and with its moderate to high THC levels (between 15% and 20%) it is beneficial for a wide array of medical issues.

That includes high blood pressure, vein wellness, chronic pain, arthritis, and depression.

Even though the ominous name may suggest otherwise, do not fret, this is a 100% quality cannabis flower.
