Hypertension

Cannabis has been studied for its potential to help manage hypertension (high blood pressure), a condition that increases the risk of heart disease and stroke. Cannabinoids, particularly cannabidiol (CBD), have shown promise in reducing blood pressure by promoting vasodilation, or the widening of blood vessels, which helps improve blood flow and lower pressure (Jadoon et al., 2009). Studies suggest that CBD can also reduce anxiety, which is a common trigger for elevated blood pressure, contributing to its potential therapeutic effects (Zhornitsky & Potvin, 2012).

Moreover, research indicates that cannabis' effects on blood pressure may differ depending on the cannabinoid involved. While CBD generally promotes lower blood pressure and relaxation, tetrahydrocannabinol (THC) may lead to temporary increases in heart rate and blood pressure, especially in higher doses (Witkin et al., 2005). This variability highlights the importance of dosage and strain selection when using cannabis for hypertension management.

Despite its potential, cannabis should not be considered a first-line treatment for hypertension. Patients with high blood pressure should consult their healthcare providers before considering cannabis, particularly if they are taking medications for hypertension, as interactions may occur. Further research is needed to better understand its long-term safety and effectiveness.
