With hypertension being a leading cause of cardiovascular disease worldwide, researchers are exploring alternative treatments to complement traditional medications. Recent studies have investigated the effects of CBD and cannabis on blood pressure in different populations, including individuals with hypertension and healthy volunteers. These findings suggest that cannabis and CBD could offer promising therapeutic benefits. 

Research shows that cannabis and cannabidiol (CBD), a compound in cannabis, may help with managing blood pressure. One study, called HYPER-H21-4, tested CBD's effects on people with hypertension. This study was carefully controlled and involved 70 patients taking CBD or a placebo for five weeks. Results showed that CBD lowered 24-hour blood pressure, including systolic and diastolic levels, without causing side effects or liver issues. However, it didn’t significantly change arterial stiffness.

Another study focused on older adults aged 60 and above with high blood pressure. Over three months, participants used cannabis through oils or smoking. The results showed reduced blood pressure, especially three hours after use, and improved their overall blood pressure patterns. While some felt dizzy, there were no serious health concerns, suggesting cannabis could be useful for older patients with hypertension.

A smaller study from the UK tested a single 600 mg dose of CBD on healthy men. The results showed lower blood pressure at rest and during stress. While participants had an increased heart rate, there were no harmful side effects. This suggests CBD could help reduce stress-related blood pressure spikes.

Observational research also looked at long-term cannabis use in over 3,000 older adults. The study found no link between lifetime cannabis use and higher blood pressure or hypertension. This data is encouraging for older adults who use cannabis for conditions like pain and anxiety, as it suggests cannabis is safe for cardiovascular health.

Overall, these studies show that CBD and cannabis can lower blood pressure, either temporarily or over time, and are generally safe for most people. However, more research is needed to confirm these findings and understand the best ways to use cannabis or CBD for blood pressure management.

These results highlight the potential for cannabis and CBD as helpful options for treating high blood pressure, especially alongside other treatments, but larger studies are needed to make it part of regular medical care.
