What you can read next CBD — Oils vs. The other major phytocannabinoid is cannabidiol CBD , which does not have psychoactive properties. CBD is currently the focus of much research due to its potential in a number of therapeutic areas, as it has been shown to have antiinflammatory, anticonvulsant, antioxidant, anxiolytic, antinausea, and antipsychotic properties 5.
A number of preclinical studies have also shown beneficial effects of CBD in a range of disorders of the cardiovascular system 6.
Epidiolex has also received orphan designation status for the treatment of neonatal hypoxia-ischaemic encephalopathy. CBD has multiple desirable effects on the cardiovascular system.
It attenuates high glucose—induced proinflammatory changes in human coronary artery endothelial cells 7 and myocardial dysfunction associated with animal models of diabetes 8 , and it preserves endothelial integrity in diabetic retinal microvasculature 9. In vivo administration of CBD before cardiac ischemia and reperfusion also reduces ventricular arrhythmias and infarct size. CBD also causes both acute and time-dependent vasorelaxation in isolated arteries in rats and humans 10 — There is also evidence from animal studies that CBD modulates the cardiovascular response to stress.
Resstel and colleagues 13 showed in rats that i. Both these effects were blocked by preadministration of WAY 0. These effects appear to be mediated centrally and involve the bed nucleus of the stria terminalis BNST , a limbic structure that modulates neuroendocrine responses to acute stress Our recent systematic review showed us that there are no dedicated studies in humans to date, to our knowledge, looking at the effect of CBD on either resting cardiovascular measurement or on the responses to stress, with continuous monitoring of CV parameters Therefore, the aim of the present study was to investigate whether CBD decreases the cardiovascular response to stress after the administration of a single dose of CBD mg in healthy volunteers, with the hypothesis that blood pressure would be reduced by CBD.
Noninvasive cardiovascular measurements were used along with stress tests in the form of mental arithmetic, isometric exercise, and the cold pressor test. Ten male subjects were recruited, but 1 withdrew for personal reasons. The mean age, weight, and height of the volunteers were Forearm blood was measured over a time period of 2 minutes just before the start and in between the stress tests.
Dotted line denotes baseline values between the stress tests. The individual blood pressure responses of healthy volunteers to the stresses are presented in Figure 2 , showing the average baseline systolic or diastolic blood pressure in the 4 minutes preceeding the stress test, the peak response during stress, and the average recovery response in the 4 minutes after the stress test.
Green color coding shows subjectS who had a reduced compared with placebo blood pressure response to stress after taking CBD, and red color coding shows an increased blood pressure response to stress after taking CBD. Measurements for forearm blood flow were made over a 2-minute window just before, during, and after the stress test. Looking at the individual response to mental stress, 6 of 9 subjects had a lower SBP before or during the mental stress test, and 9 of 9 subject had a lower SBP in the recovery period after taking CBD Figure 2.
Looking at the individual response to exercise stress, 6 of 9 subjects had a lower SBP during isometric exercise and 8 of 9 subjects had a lower SBP in the recovery period after taking CBD Figure 2.
There was no difference in CO during the exercise stress Figure 4F. Looking at the individual response to the cold pressor test, 8 of 9 subjects had a lower SBP during the cold stress and in the recovery period after taking CBD Figure 2. Based on preclinical evidence, the aim of this study was to test the hypothesis that CBD would reduce the cardiovascular response to stress in healthy volunteers.
We found that resting blood pressure was lower after subjects had taken CBD and that CBD blunted the blood pressure response to stress, particularly in the pre- and poststress periods. These hemodynamic changes should be considered for people taking CBD and suggest that further research is warranted to establish whether CBD has any role in the treatment of cardiovascular disorders. We have shown for the first time that to our knowledge that, in humans, acute administration of CBD reduces resting blood pressure, with a lower stroke volume and a higher heart rate.
This response may be secondary to the known anxiolytic properties of CBD 16 and may account for the lack of anticipatory rise in blood pressure seen with placebo. These findings are in contrast to previous studies in humans, where CBD at the same dose did not affect baseline cardiovascular parameters 17 — 19 , although changes in the cardiovascular system were not the primary outcome of these studies. In the present study, CV parameters were measured continuously, while in previous studies, monitoring for SBP, DBP, and HR were performed manually at only 1, 2, or 3 hours after drug delivery.
Additionally, our subjects were cannabis naive, while the subjects of other studies had used cannabis in the past. Since tolerance may develop to the hemodynamic response to CBs in humans, this may explain the differences between studies.
THC, the major psychoactive component of cannabis, is known to cause tachycardia and orthostatic hypotension in humans 20 , a hemodynamic response similar to that observed to CBD in the present study.
We recently showed that CBD also causes endothelium-dependent vasorelaxation in isolated human mesenteric arteries through CB 1 activation Therefore, it is possible that the changes in hemodynamics brought about by CBD are mediated through CB 1. CBD may cause sympathoinhibition through CB 1 or some other mechanism , thereby preventing an increase in blood pressure and cardiac output, causing a compensatory rise in heart rate to maintain cardiac output. Another possibility is that CBD inhibits cardiac vagal tone, thereby increasing heart rate despite any potential sympathoinhibition.
The same study showed that pretreatment with atropine and propranolol fully abrogated the HR response, suggesting a role for the autonomic nervous system. Mental arithmetic has been shown to cause a rise in MAP and muscle sympathetic nerve activity MSNA 25 and vasodilatation in forearm skeletal muscle In our study, none of the cardiovascular parameters other than HR, DBP, and SV were affected, suggesting that the level of stress to this test was minimal.
This could be because of the added visual stimulus of a computer screen, which would have helped volunteers perform the task. Isometric exercise produces a pressor response, via sympathoexcitation, originating in the contracting muscle and relayed to the RVLM via the nucleus of solitary tract.
The end result is a rise in heart rate and cardiac output and vasoconstriction in nonexercising organs 27 — There is increased skeletal muscle blood flow in the nonexercising limb, which is sensitive to atropine and propranolol A similar response was seen in our study, where isometric exercise caused a significant rise in SBP, DBP, MAP, and HR and an increase in forearm blood flow, although this was significant in the placebo group only.
Subjects who had taken CBD had reduced blood pressure during the exercise stress test, and this was most pronounced in the pre- and posttest period. Before the exercise stress, HR was higher and SV lower in volunteers when they had taken CBD, and this trend continued throughout exercise stress and in the poststress period.
Cold stress causes intense sympathoexcitation, producing a tachycardic and pressor response, and an increase in MSNA 32 , In our study, cold stress produced a pressor response in both groups, but, interestingly, while SBP and MAP continued to rise with placebo throughout the test period, the pressor response to cold was blunted in subjects who had taken CBD, and SBP and MAP were significantly lower.
This could also be due to analgesic properties of CBD 35 , reducing cold stress and therefore minimizing the sympathetic response also explaining why the cold pressor test was affected more by CBD than the exercise test. In the animal study of Resstel and colleagues 13 , the authors suggested that the modulation of cardiovascular response was most likely secondary to attenuation of emotional response to stress.
However, given our findings that CBD produced similar changes in cardiovascular parameters — though to a variable degree — during rest and stress, this may indicate that CBD also has direct cardiovascular effects. CBD was well tolerated, and there were no adverse events on the day of stress tests. None of the subjects reported any adverse events over the following week.
Our data show that a single dose of CBD reduces resting blood pressure and the blood pressure response to stress, particularly cold stress, and especially in the post-test periods.
This year has been disastrous due to taking too high a dose of vitamin D and cannabis oil simultaneously, both of which lower my blood pressure. When I stand up, my blood pressure drops.
To compensate the heart rate rises. My heart will raise to beats on standing often. I also get tachycardia when the orthostatic intolerance gets really bad. CBD oil I should imagine is very useful for people with high or normal blood pressure, but not for someone with pre-existing orthostatic problems or problems with veins not constricting on standing etc… There are various causes to POTS like problems like mine, be it autonomic failure, hypermobility etc… but people with these conditions need to be careful what they take.
Any product that lowers blood pressure or causes vasodilation is a no go. In the United States, not so much. It is less common than high blood pressure…. Sometimes if I need to get up in the night I am not careful enough and I fall. In people who are in awesome CV condition long distance runners , resting HR and BP can be extremely low some have been mistaken for having a medical emergency.
However, the same effect exists in powerlifters who are overweight not fat; too much large, dense muscle. There is a correlation for every type of person. Hope this helps clarify. Learning first aid in h. However, I had the genetics, I was super-skinny and I got more than enough exercise. MJ-induced low blood pressure worries me though.
This is not the good, heatlhy kind of low resting levels. This is with low levels of exercise. It is different for everyone, like you say, MikeG. I try to go by what feels right, but there are steep learning curves involved. I am on narcotics for chronic back pain. For 3 months, so much pain was taking more narcotics, my BP was very low. Last Saturday, I got state approved Marijuana card. I was on higher doses of beta blockers for the past 10 years.
A few days into using them consistently and my pressures dropped too low. I gave it a break and then tried again numerous times, each time resulting in lowered BP. I was planning on treating my post op pain with cannabis, but my BP was too low for the first few days following surgery. I would love to ditch the pills and rely only on the plant! Each of us are made up differently and react differently. Is your tincture grape seed oil?
Do you take meds for your hypertension now? Best of luck to you! I really hope you can make the transition from pharmaceuticals to Cannabis.
At least on your chronic pain end of things. I was on heavy doses of narcotics for years. They mask the pain for a little while, only to have to continue to increase your dose. I hope you get the opportunity to give it a good go without the issues with your BP! I was diagnosed last year with secondary hypertension after nearly 70 years of low to normal blood pressure. I only took the morphine in the last years. I have so little pain now with regular daily use of the cannabis.
However, my blood pressure has not gone down. Today, she prescribed a different medication. My mother died from taking meds that counter-acted the side effects of other meds so that she ended up taking handfuls of pills every day until her heart just stopped when she was Sounds like you were taking Lisinopril.
I took it and had that same cough. The doctor took me off of it right away, but it took a week to go away. My mother started using pure cbd oil a few months ago. She has a heart condition and high blood pressure. It really seems to help her out and with her moving and going all day brings so much joy after a bad scare we had last year. This is the oil she purchased and swears by it! Cannabinoid resin has been found in pipes by archaeologists. The information on the benefits cbd has on us is timeless.
This might be pertinent: I have low blood pressure for a number of reasons… One of them is simply genetics. Now, marijuana lowers my blood pressure so much that one of my doctors did not want me to join the medical marijuana program in my state. I eat extra salt, rather than cutting it out of my diet. Low blood pressure can also cause dizziness and even disorientation. If you have medical equipment at home, checking a pulse-ox can be important and a good indicator if something is wrong.
Fainting is not uncommon. It can be unsafe to drive. Hell it is unsafe to walk, at some of those numbers. In fact, low blood pressure is as much a hazard as high blood pressure — it is just less commonly known. Those with HYPOtension need to be educated, too. I use marijuana for pain control and PTSD and I am very careful with this medication that has a side effect of lowering blood pressure.
Er I meant to say, you probably already had a tendency towards low blood pressure and the pot lowered it more. Sorry it took me 6 months to answer! And yes, that very well may be true. Thanks for your reply. The Harvard study only relates to combustion, which is likely the reason for the increased risk.
Additionally, THC lowers blood pressure. I may be one of the lucky ones who was able to stop using drugs when I started using cannabis for an unrelated condition. I do use a high CBD strain and that may play a role in this. My BP is usually around to however If i quit cold turkey for say a job it can spike to to right about the four day quit mark.
So be careful especially if your bp is up there. Will Hemp oil help Essential Tremors? I, as I have mentioned earlier.
I am 88 and was born with Essential Tremors. Not too sure about hemp oil. What you need is a compound called CBD. CBD doesnt get you high and it is completely safe to use. One amazing thing I have noticed is the vast amount of improvement in my asthma due to cannabis use. Along with my meds, my family has a history of large men with heart and CV problems that generally lead to heart attack at one point or another. Strong Heart, poor plumbing.
The paternal side of my family all males have had bypass some very young. All have died of heart failure. I recently began using cannabis. My blood pressure now has not been this stable in some time. Have always struggled with BP. Am on 4 different BP meds at max doses. Not sure what all long term effects of all these meds are.
I guess kinda like cannabis and log term effects Not only the BP but a smile, a laugh, relaxation. So, I should stop why?
