    I hear this happens to a lot of people but I just wanted to make sure.
    When I get high it really affects my heart rate. Right now it's 116 bpm at rest.
    Wait... 95
    Dude maybe I'm just having trouble measuring it.
    Hold on... 120 ... 108
    Crap I'm having trouble measuring it

    It's up there though, and pumping hard.
    Any comments?


    Whoops, forgot I started this.

    The point is, does your heart pump hard and fast while high? My normal heart rate while at rest is something like 45-60.

    Marijuana can speed up your heart beat, an increase of around 45%.¹ The effect on the heart though is of negligible clinical significance in healthy users because tolerance develops to them.²

    Your blood pressure can increase while sitting/laying down, and decrease when you stand up.

    Cannabis will not cause a heart attack in a healthy user. But if you have some sort of a medical condition related to your heart, it can be a concern to your health.

    Eh, I left the computer going for a while without finishing my message. Look at the bottom part.

    45% increase would explain it. I knew your heart was supposed to speed up but I didn't expect that much.

    Never really noticed it before now.

    Also, it could be from going without smoke for a couple weeks - my tolerance is lower, so my heart beats faster.

    It isn't always exactly 45%. It can be up to 45%.

    The negligible clinical significance part simply just means that your body becomes tolerant to the effect that THC has on your heart. This means that repeated dosage will result in a less of an effect on your heart (it doesn't cause a large increase in beats as it used to), or it could totally stop increasing your heart rate.

    Ya, it does increase.

    Anybody seen that car comercial(medcedes?) where they say "doctors say its healthy to elevate your heart rate once a day, well here's to your health." First thing I thought, was replace the car with marijuana and you got a good comercial. Just a thought.

    hey. When i was born i had a heart problem. Like this valve was to small and no blood could get through. So when I was just 3 days old i had to have heart surgery. Luckily, i made it. Im 15 now and have been smoking pot for a few months. I was just wondering, does weed affect your heart. Or could it be worse for my heart than others who haven't had surgery? please help.

    Im not exactly sure. how long have you been smokeing? any problems yet?
    i would highly doubt it, when intaking marijuana it does increase the heart rate, which i think/though would be good for you.
    But hell if i know if it doesnt bother you then keep tokeing, if it bothers you everytime you smoke it(mentally not just physically, like thinking twice about smokeing) then i would say dont.

    If you aren't experiencing heart pains, chest pains, etc., then don't worry about it. I don't see how smoking would make you have a heart attack or something, it's not like you're taking cocaine.

    Weed will signifigantly increase your heartrate, somewhat as if you had been excercising.

    I've heard that your up to 4 times more likely to have a heart attack if your stoned for this reason. Thats not really a problem if you have a healthy heart, but if your allready at risk for a heart attack you would be increasing your chances of heart failure while high. (The same is true when excercising or doing any activity that increases heartrate and or bloodpressure.)

    Are you ok to play sports, excercise etc? If so then I'd imagine you should be fine. Im not a doctor however so you should take my oppinion with a grain of salt. If you want to be sure ask a doctor.

    Hey another patent ductus arteriousus survivor!

    ...back in the stone age...when I was born...they waited 3 months to do the surgery...

    You should be fine.

    I am assuming that you have had no chest pains, are able to exercise normally like everyone else without shortness of breath and your doctor has not warned you of any other concerns...

    The increases heart rate after smoking weed is about synonymous with a humnan having sex incrreased heartrate is not in and of itself something to be concerned about.

    One thing you do want to ask your doctor, many of us who have had heart surgery are told to be careful about infection during future surgery, especially dental surgery (!) and are told to take an antibiotic prior to any procedures (including dental cleaning). Speak with your doctor about wheterh you require an "antibiotic prohylaxis" prior to surgery or surgical procedure. If so, do keep a message in your wallet or have a health bracelet or charm in case of emergency when you can't speak for yourself. have a cookie ;)

    Marijuana and your heart?

    I did a search and couldn't find anything really. How does Marijuana affect your heart? My grandfather died of a heart attack and my father has also had a heart attack. Neither of them were un-healthy and my father ran/runs 6 miles a day and works out. Could Marijuana play a role in either cause or prevention of heart attacks?

    im not sure, but i do know that it speeds up your heart rate, so im guessing it wouldnt be great for your heart.

    As mentioned, cannabis can cause an increase in your heart rate. This is because it dilates your blood vessels, and your blood pressure drops. As a result, your heart beats faster to make up for this.

    However, tolerance develops to this. In fact, regular users may experience bradycardia, or a slowing of the heart rate when using cannabis.

    As for something like heart attacks, if you've suffered one in the past, or have some other heart disease, you may want to avoid cannabis.

    What a fantastic subject. I think one thing I have never mentioned to is the fact I use marijuana to control my blood pressure. In this way, marijuana is fantastic to the heart. I have seen articles that imply marijuana use is the same for the heart as excercising.

    High blood pressure, or hypertension, afflicts between 10 and 20 percent of adults in Western societies. This condition puts a strain on the heart and blood vessels and greatly increases the risk of stroke and heart disease.

    Research is currently being conducted at the University of Nottingham Medical School (U.K.) to better determine the effects of endocannabinoids, cannabis-like chemicals produced naturally by the body, on circulation. (1) Scientists recently discovered that the endocannabinoid anandamide relaxes blood vessels, which can reduce blood pressure by allowing blood to flow more freely, but do not yet comprehend how they are produced or cause changes in the body. (2)

    Lead researcher Dr. David Kendall of the Queen's Medical Centre says: "This research should tell us a great deal more about how these substances affect our circulation. This is a new and exciting area of research which could ultimately lead to better treatments for a range of cardiovascular diseases." (3)

    In his book Marihuana the Forbidden Medicine, Dr. Lester Grinspoon (with James Bakalar) recounts one patient's account of using cannabis to successfully treat hypertension. "Cannabis is … the first drug that has been effective in controlling my high blood pressure," the patient writes. "I have taken so many others that I can't remember their names, but the result was always the same: they either didn't work or caused such horrible side effects that I needed more drugs, which only raised my blood pressure again. Since I began smoking cannabis, my blood pressure has remained relatively constant at 130 over 80." (4)

    Former California gubernatorial candidate Steve Kubby also gives strong anecdotal evidence of cannabis' ability to control hypertension. Kubby has used inhaled marijuana to control hypertension associated with malignant pheochromocytoma, a usually fatal cancer he contracted 15 years ago. (5) Several of Kubby's phsysicians, including Dr. Vincent DeQuattro of the hypertension diagnostic laboratory at the University of Southern California Medical School, speculate that his marijuana therapy may have extended his life. "In some amazing fashion, this medication has not only controlled the symptoms of the disease, but in my view, has arrested growth," DeQuattro says. He adds that he knows of no other patient who has survived as long with the disease. (6)

    The House of Lords Science and Technology Committee report on medical cannabis acknowledged that smoking cannabis can lower blood pressure, but warns that it may also increase heart rate in some users (7). They concluded that the latter effect may pose a health risk for patients with a history of angina or other cardiovascular disease, and recommend that they be excluded from any clinical trials of cannabis-based medicines.
