There may be other effects of marijuana on blood pressure that health practitioners have yet to discover. All potential effects depend on the individual’s existing health problems, especially co-morbid conditions such as diabetes and obesity.
Since smoking a joint can lead to a relaxing high, you might wonder about cannabis use and its effect on blood pressure. We know that weed can make your eyes red , but does it also raise or lower blood pressure, or does it not have any effect at all? If you have high blood pressure, is marijuana safe to consume?
“THC can affect blood pressure depending on the dose, the route of administration, a person’s experience with THC, and a person’s underlying health. Healthy volunteers that took THC had an increase in heart rate and decrease in blood pressure. In studies where people used THC while lying down, they had elevated blood pressure. When they stood up, their blood pressure dropped and they experienced low blood pressure.”
You might also be wondering, what if you’re smoking weed while taking blood pressure medication? Will there be an adverse reaction? If you are smoking THC-rich cannabis and taking medication for high blood pressure, the answer is that there could be.
Goldstein explained, “Smoking cannabis can be harmful for those with heart disease or hypertension since the smoke contains carbon monoxide. This gas binds to the hemoglobin in red blood cells, displacing oxygen off of the red blood cells which results in less oxygen going to the body’s tissues, including the heart. People with heart disease or high blood pressure should avoid smoking.”
Another frequently asked question about cannabis and cardiovascular health is: can weed cause a heart attack?
These sudden drops in blood pressure, also known as white outs or green outs, may indeed be linked to cannabis use. Dr. Melanie Bone, a board-certified OB-GYN and cannabis specialist who practices in West Palm Beach, Florida, told Weedmaps that “cannabis may cause a drop in blood pressure on standing — known as postural hypotension.” This type of drop in blood pressure is not desirable, as it can cause vertigo and even fainting. So, when we talk about “lowering blood pressure,” we do not necessarily consider that effect beneficial to health.
Hypertension is the medical term for high blood pressure. As blood is pumped through your blood vessels, they undergo a degree of force. If you have high blood pressure, this force can damage the walls of your blood vessels, veins and arteries.
Inflammation doesn’t only occur in your joints. In fact, research shows that CBD oil can reduce inflammation in the heart and blood vessels in the brain.
Lowering High Blood Pressure: CBD and Blood Pressure
As CBD reduces stress, you may see an increase in your quality of sleep and general wellness.
While Park told us that high blood pressure can be caused by a number of factors, CBD oil appears to lower increases in blood pressure caused by stress and anxiety.
In a 2018 study, researchers found that a dose of 300 mg was most effective for reducing anxiety in a simulated public speaking trial. Participants who took 150 mg or 600 mg did not receive the same benefit.
