Does cannabis help with blood pressure? According to a cursory study, it might, but the results are a bit conflicting, with a limited amount of people actually showing different benefits. Some say that it may be a good agent to help with this.
High blood pressure is an epidemic, and this is actually responsible for over half a million deaths within the US alone. This of course, increases risk for stroke, heart disease, and death of course, with the prevalence increasing as you get older, and only about a quarter of adults have hypertension they’re controlling. This is serious, so it’s no wonder why people haven’t taken care of it, and also why they haven’t gotten the full ability to control this yet.
Endocannabinoids and your Heart
The endocannabinoid system is a big part of our body, with different neurotransmitters including 2-AG and anandamide as well in these, and they can actually be active receptors directly to the heart, helping with cardiac motions. It can also help with decreasing the damage to the tissue, along with arrhythmia, and in some cases they can halt the progression of other heart-related conditions including atherosclerosis.
There is also some overwhelming evidence that this can actually help with vasodilation, reducing and normalizing the pressure of the blood. This can help to suppress cardiac contraction and hypertension, and also may help with normalizing the blood pressure further.
Cannabis and Your blood pressure
There was some animal research done clinically that establishes that THC does work to help with lowering the blood pressure of an animal. The findings did push for the use of medical cannabis to help with this, and in another study in 1979, it was found that those subjects that inhaled THC did have a small increase in their heart rate, and then the systolic and diastolic blood pressure dropped, and this of course, would last up to four hours, and sometimes was a bit more intense compared to other hypertension subjects that were studied.

The enthusiasm did push for the potential of this, but this did get tempered when according to reports of the effects of medical cannabis treatments, it was found that the tolerance for this did help negative the hypotensive benefits of this, and other studies mentioned no particular evidence when it came to the development along with tolerance that was associated with the usage of THC continuously.
According to a study that was published in Hypertension it was found that a lot of users who were middle-aged did have a small increase initially, but there was no increase in the diastolic blood pressure readings. Other studies said that they don’t have an initial increase, but instead, there was a soloing of the blood pressure along with the heart rate.
This also has been further looked into. And, in a study in 2021, it wsa found that those who were prescribed the use of medical cannabis did have lower levels of diastolic and systolic blood pressure, with the main effects happening about three hours after the initial use of cannabis.
While it seems like it may work, a big part of this is actually there are some other health concerns. Including the frequent usage of marijuana through smoking did result in higher chances of myocardial infarction along with stroke, and coronary artery disease, with a possible chance for cardiovascular disease prematurely.

But, this type of thing doesn’t have the full risks associated with this, and there are other variables including the consumption of a
