Access To Marijuana Is Growing But Marijuana Benefits And Its Risks Have Not Been Carefully Studied
In many states in this country, you can legally use marijuana for a range of health benefits, including the treatment of chronic pain, anxiety, and nausea. Smoking is the fastest way to feel the effects of marijuana, which is derived from the Cannabis sativa plant. Yet marijuana smoke contains many of the same toxins, irritants, and carcinogens found in cigarette smoke a known contributor to heart disease as well as cancer.
Marijuana cultivation and use dates back some 6,000 years. However, the cardiovascular and other health effects of cannabis aren’t well studied. That’s partly because under federal law, cannabis is a Schedule I substance, meaning it has “no currently accepted medical use and a high potential for abuse.” That designation places numerous restrictions on researchers, making it difficult to carry out rigorous research on marijuana.
“As a result, everything we’re told about what marijuana does or doesn’t do should be viewed with a certain amount of caution. This holds equally true for the risks as well as the benefits,” says Dr. Kenneth Mukamal, associate professor of medicine at Harvard-affiliated Beth Israel Deaconess Medical Center.
Does Smoking Cause Increased Heart Rate
First of all, theres no doubt that smoking causes various heart problems. These can range from atherosclerosis to decreased heart function. Atherosclerosis is narrowing and hardening of the blood vessels essentially plaque buildup. When your vessels are narrow, your heart has to work twice as fast to pump blood, which puts a lot of strain on it. Eventually, this can cause something thats called an enlarged left heart syndrome, which basically means that the left side of your heart expands and weakness because of all the work it needs to do pump blood through your body. Also, you have greater chances of suffering from a heart attack or stroke because the plaque in your arteries can get dislodged and cause all sorts of problems.
However, does smoking increase your heart rate? This is still a controversial issue and more studies are needed to confirm it. Its important because elevated heart rate is not healthy athletes have a resting heart rate between 40 and 60, and regular Joes around 80 bpm.
Some studies have found that smokers have an increased HR at rest, while having a lower HR increase when exercising. Also, their peak HR during extraneous circumstances seems to be lower than that of non-smokers.
On the other hand, other studies show that smokers have a pretty much similar heart rate to non-smokers when they are not smoking. When they are smoking, their heart rate can increase by almost 30% .
Fda Plans To Make Cigarettes Less Addictive
In 2017, FDA Commissioner Scott Gottlieb, M.D., announced the agencys intention to lower nicotine levels in cigarettes to minimally addictive or nonaddictive levels. While this action would not remove cigarettes from the market, reducing their addictiveness would help addicted adult smokers quit altogether or switch to potentially less harmful tobacco products.

Cbd Effects On Heart Rate
Cannabidiol, also known as CBD, has become a growing product on the market. While more research is needed to fully understand what all this cannabinoid offers, studies show promise on its potential health benefits. Of these potential benefits, CBD may even have an effect on stabilizing the heart. Other potential benefits include calming the brain, helping with psychosis, and improving a persons ability to focus. All of these benefits are essential to understanding what CBD may be capable of.
So you may be wondering whether or not CBD is going to have a positive effect on your heart, in particular your heart rate. And we understand why! The heart is a vital organ responsible for circulating oxygen and nutrients throughout the body. So lets take a deeper look at how the effects of CBD might impact the heart rate.
If You Dont Think The Thc Levels Are The Culprit Next You Should Next Check The Strain
There is no strain that will completely negate the racing heartbeat caused by cannabis. But, there are some that are better than others. If you can chose, smoke a heavy indica. Indicas give a much more relaxed high due to their high CBD content, a compound, which can counteract THC. Make sure youre in a relaxing environment when you smoke, whatever that may be for you. Sativa strains are more energizing and uplifting which can cause some users to experience anxiety or panic, which will then lead to palpitations and paranoia. If youve been smoking sativa strains often, try switching to indica or indica-dominant hybrids and see how it goes. If youre looking for a strain that will negate this effect entirely, youre looking for a strain that wont get you high.

Effects Of Vaping And Cbd
For those who prefer vaping, you may be familiar with the increased heart rate you feel after vaping. This is likely because vaping has been known to increase your heart rate and blood pressure. Several health-related illnesses are also known to be the result of vaping. And so, it is not recommended to consume CBD through vaping.
However, you may be wondering if ingesting CBD could help to combat the increased heart rate experienced by vaping. Further research is needed before we can understand the effects of vaping and CBD. But as mentioned, if you are looking to experience any of the potential benefits of CBD, it is always important to speak with your doctor first.
Reports Of Deaths Related To Vaping Marijuana
The Food and Drug Administration has alerted the public to hundreds of reports of serious lung illnesses associated with vaping, including several deaths. They are working with the Centers for Disease Control and Prevention to investigate the cause of these illnesses. Many of the suspect products tested by the states or federal health officials have been identified as vaping products containing THC, the main psychotropic ingredient in marijuana. Some of the patients reported a mixture of THC and nicotine and some reported vaping nicotine alone. No one substance has been identified in all of the samples tested, and it is unclear if the illnesses are related to one single compound. Until more details are known, FDA officials have warned people not to use any vaping products bought on the street, and they warn against modifying any products purchased in stores. They are also asking people and health professionals to report any adverse effects. The CDC has posted an information page for consumers.
One complexity in comparing the lung-health risks of marijuana and tobacco concerns the very different ways the two substances are used. While people who smoke marijuana often inhale more deeply and hold the smoke in their lungs for a longer duration than is typical with cigarettes, marijuanas effects last longer, so people who use marijuana may smoke less frequently than those who smoke cigarettes.

Cannabis And Acute Coronary Syndrome
From the Determinants of Myocardial Infarction Onset Study cohort, in a case-crossover study, Mittleman et al. interviewed 3882 patients with acute myocardial infarction to compare the reported of use of marijuana in the hour preceding symptoms onset to its expected frequency using self-matched control data. They found that marijuana smoking was associated with increased the risk of MI 4.8 times than baseline within one hour of use but this elevated risk appears to decrease rapidly thereafter. Further, the annual risk of MI in daily users of cannabis was calculated to be 1.5% to 3% per year . In another study from the similar cohort, 1913 patient were prospectively followed for an average of 3.8 years between 1989 and 1996 with 52 patients reported to consume marijuana within a year. The authors determined that compared to non-use, cannabis use less than a week, was associated with hazard ratio of 2.5 and weekly or more use was associated with hazard ratio of 4.2 . Any cannabis use was associated with hazard ratio of 1.9 for cardiovascular mortality and 4.9 for non-cardiovascular mortality after age and sex adjustments . However, in a follow study from the same cohort, Frost et al. could not demonstrate statistically significant association between cannabis use and mortality after 18 years of follow up.

Physiological Effects Of Smoking Marijuana
When you smoke marijuana, your heart rate and blood pressure increase. At the same time, smoking in general, whether tobacco, marijuana or a mixture of the two, reduces the capacity of the blood to deliver oxygen throughout the body an effect of the products of combustion such as carbon monoxide. This combination adds up to increased risk for a cardiac event like a heart attack, particularly while a person is smoking and immediately afterward.
There is a strong case for saying no one should ever smoke marijuana because of the products of combustion, said Dr. Pipe. We can say with absolute certainty that smoking marijuana will harm the ability to deliver oxygen, and thats not good.
While Dr. Reid pointed out that the relationship between marijuana use and heart disease remains, at this point, largely theoretical, there is existing evidence that marijuana use may lead to quicker onset of exercise-induced angina during a stress test among people with heart disease. This suggests another reason why it is not a good idea to use marijuana, he noted. He also noted that marijuana use could be problematic for people with an irregular heartbeat, or arrhythmia, because it activates the sympathetic nervous system.

Questions Remain On Marijuanas Benefits And Risks
Most of the evidence linking marijuana to heart attack and stroke is based on reports from people who smoked it. So it’s hard to separate the effects of cannabinoid compounds on the cardiovascular system from the hazards posed by the irritants and carcinogens contained in the smoke. Because cannabis smoke is known to cause airway inflammation, wheezing, and chest tightness, people with lung diseases should not smoke it. Other people who should just say no to marijuana include those who may be vulnerable to developing schizophrenia or addiction.

The Problem With Assessing Impact
In theory, it shouldnt be that difficult to assess the impact of marijuana use. In reality, though, its actually difficult to untangle.
For one thing, marijuana is rarely used in isolation. Generally, tobacco, alcohol or both are involved. And while the amount smoked is less with marijuana, experience has shown that smoking marijuana can make it harder to quit smoking tobacco. In reality, most people use the two together, thus, as Dr. Reid punned, clouding the issue.
Significant numbers of individuals who smoke lots of marijuana daily come to us because they want to stop smoking, said Dr. Pipe. But for heavy marijuana smokers mixing it with tobacco, the likelihood of quitting is much less.
Another problem relates to dose control. There are no standards for the production of marijuana and the amount of THC it contains. The problem becomes more acute when marijuana is eaten, said Dr. Pipe. People who eat marijuana may not feel the effect as quickly as those who smoke it, leading them to use more.
How Other Cannabinoids Affect Cardiovascular Health
Left: THC directly stimulates the CB1 receptor. This interaction underlies the major psychoactive effects of cannabis consumption. Right: CBD reduces, or antagonizes, THCs ability to stimulate CB1 receptors.
Two of the most abundant phytocannabinoids other than THC are CBD and tetrahydrocannabivarin . CBD can block THCs ability to activate CB1 receptors and could protect against some of the harm caused by the drop in blood pressure and elevated heart rate caused by THC alone.
On its own, CBD is a potent antioxidant and neutralizes harmful free radicals. It also has strong anti-inflammatory abilities which can reduce the damage caused by activation of CB1 receptors. Indeed, CBD has beneficial effects on cardiovascular risk factors and improves recovery in animal models of heart attack and stroke.
THCV has pro-cardiovascular effects by blocking CB1 receptor function at low doses. Its through this mechanism that THCV is thought to reduce insulin sensitivity in obese mice, which reduces risk for cardiovascular events. And like CBD, THCV has been shown to be safe in Phase II clinical trials. THCV becomes an activator of CB1 receptors at high does, but in most strains of cannabis, THCV levels are too low to activate them.

Effects Of Cbd And Heart Rate Medication
Heart rate issues can lead to a long list of problems making it important to maintain a healthy lifestyle. Because of this, doctors will often prescribe a heart rate treatment to help alleviate the symptoms as soon as possible. This medication is known to help stabilize the heart rate in all types of situations.
While CBD may positively impact the heart rate, its important to understand that you should always consult your physician before taking CBD for any conditions, including those that are heart-related. This is particularly true if you have a health condition or are taking any medication.
Does Cannabis Raise Your Heart Rate
Weed affects your body in all sorts of ways, but does cannabis raise your heart rate? We dont have to rely solely on anecdotes or personal experiences. Research has helped map out some of the ways that cannabis interacts with and affects our bodies. In particular, cardiovascular health is one area that researchers have looked at. So, does cannabis raise your heart rate? Heres what we know.

Variability In Cannabis Type And Use Patterns Makes Studies In Humans Challenging
Your average dispensary has a massive range of cannabis products available. Some are rich in THC, while others are low in THC. Some have high levels of other cannabinoids, like cannabidiol , which can have opposite effects on the brain and body as THC. But most studies looking at the impact of cannabis on cardiovascular health only control for general use patterns, not type of cannabis.
The studies usually dont control for THC consumption or the presence of other cannabinoids. The larger assessments of the impact of statewide legalization on cardiovascular events in the states population dont even assess whether these events occurred in cannabis users, thereby assuming that increased cannabis access is the variable that changed the mortality rate. So when someone says that cannabis use increases risk for cardiovascular events, the next questions should be what type of cannabis? And how often are they using?
To better understand the impact of cannabis on the heart and vasculature, lets unpack the contribution that the endogenous cannabinoid receptors type I and II have on cardiovascular function.

- Does smoking increase heart rate and why?
- Q: UGH i DONT smoke people, i would like an answer to understand the mechanics of biology. Thank you to those you answer properly. Please do not answer if you do not know the scientific detail.
- A: From the moment smoke reaches your lungs, your heart is forced to work harder. Your pulse quickens, forcing your heart to beat an extra 10 to 25 times per minute, as many as 36,000 additional times per day.Because of the irritating effect of nicotine and other components of tobacco smoke, your heartbeat is more likely to be irregular. This can contribute to cardiac arrhythmia, and many other serious coronary conditions, such as heart attack. A recent Surgeon Generals report estimated that about 170,000 heart attacks each year are caused by smoking.

In addition to permanently damaging your heart and blood vessels, cigarette smoke can also cause CVD by changing your blood chemistry1,2 and causing plaquea waxy substance comprised of cholesterol, scar tissue, calcium, fat, and other material3to build up in the arteries, the major blood vessels that carry blood from your heart to your body. This plaque buildup can lead to a disease called atherosclerosis.
When the chemicals in cigarette smoke cause atherosclerosis and thickened blood in the arteries, it becomes more difficult for blood cells to move through arteries and other blood vessels to get to vital organs like the heart and brain.4 This can create blood clots and ultimately lead to a heart attack or stroke, even death.1,2
