Cannabis comprises a myriad of compounds, but the most studied are tetrahydrocannabinol (THC) and cannabidiol (CBD). When consumed, these compounds interact with the body's endocannabinoid system, a complex system known to play a crucial role in maintaining homeostasis, including blood pressure regulation.

  1. Initial Increase in Heart Rate and Blood Pressure: After consuming cannabis, there's often an initial increase in both heart rate and systolic blood pressure. This effect is predominantly attributed to THC. It stimulates the sympathetic nervous system, leading to the release of neurotransmitters like norepinephrine.

  2. Post-Consumption Drop in Blood Pressure: Following the initial surge, there's a notable drop in blood pressure, a phenomenon known as the hypotensive effect. The exact cause remains a topic of debate, but some theorize it may be related to the dilation of blood vessels, which reduces resistance to blood flow.

  3. Influence on Blood Vessels: Both THC and CBD can induce relaxation in the walls of the arteries. Such relaxation can lead to decreased blood pressure. While this effect may seem beneficial, especially for those with hypertension, it's essential to consider the potential risks of a sudden drop in blood pressure or the implications for those with low blood pressure.

  4. Interactions with the Renin-Angiotensin System: The renin-angiotensin system plays a significant role in blood pressure regulation. Recent studies from the Journal of the American College of Cardiology indicate that cannabinoids might influence this system, potentially leading to changes in blood pressure levels.

  5. Consideration for Older Adults: As we age, our cardiovascular system undergoes several changes. Kidney function may decrease, and there might be existing health problems or prescription medications in the mix. The way older adults' cardiovascular systems respond to cannabis can be quite different from younger individuals, making it essential for them to approach cannabis use with caution.

To understand the potential therapeutic benefits or risks of cannabis on hypertension, it's paramount to consult healthcare professionals who are informed about the latest research in the field.
