Understanding the Link Between High Blood Pressure and Quitting Weed

Understanding the Link Between High Blood Pressure and Quitting Weed

Quitting weed can be a significant decision for individuals who have been using it regularly. While many people are aware of the potential effects of marijuana on mood, sleep, and appetite, there is limited knowledge about its impact on blood pressure. In this article, we will explore the relationship between high blood pressure after quitting weed. We will delve into the available research, examining both the potential for marijuana to lower or raise blood pressure and the implications for individuals who are considering quitting.

What is Blood Pressure?

Before we dive into the effects of quitting weed on blood pressure, it's essential to understand what blood pressure is and how it is measured. Blood pressure refers to the force exerted by circulating blood against the walls of the arteries as the heart pumps it. Blood pressure is typically measured using two numbers: systolic pressure over diastolic pressure. The systolic pressure represents the force when the heart contracts, while the diastolic pressure represents the force when the heart is at rest between beats.

High Blood Pressure After Quitting Weed

The effects of marijuana on blood pressure are complex and still not fully understood due to limited scientific research. However, some studies suggest a potential link between marijuana use and blood pressure regulation. One study conducted in 2005 found that cannabis contains compounds that may help lower blood pressure by affecting cannabinoid receptors near the heart. Additionally, cannabidiol (CBD), a component of marijuana, has been found to potentially impact the part of the autonomic nervous system responsible for regulating heart rate in response to environmental changes.

However, more recent research is needed to establish a definitive connection between marijuana use and blood pressure regulation. A study from 2021 observed that older participants with hypertension experienced lower levels of systolic and diastolic blood pressure for 24 hours after using cannabis. While these findings are promising, it is important to note that this study was the first of its kind and further research is required for a deeper understanding.

Potential Effects of THC Withdrawal on Blood Pressure

When it comes to quitting weed and its effects on blood pressure, the research is even more limited. However, we can draw some insights from studies on smoking and its impact on heart health. Smoking cigarettes has been shown to increase inflammation, narrow veins and arteries, and raise blood pressure. While tobacco and marijuana are different substances, smoking any substance can potentially have negative effects on cardiovascular health.

When individuals quit smoking cigarettes, they often experience a temporary increase in blood pressure. This temporary rise in blood pressure could also occur after quitting weed, as the absence of marijuana may impact the body's physiological responses. However, more research is needed to determine the time course and magnitude of this effect. It is crucial for individuals considering quitting weed to monitor their blood pressure and consult with healthcare professionals for personalized advice in order to prevent THC withdrawal blood pressure.

Does Quitting Weed Cause High Blood Pressure?

When someone decides to quit weed, they may experience a range of withdrawal symptoms as their body adjusts to the absence of THC, the active compound in marijuana. These symptoms can vary in intensity and duration depending on factors such as frequency of use, dosage, and individual physiology. Common withdrawal symptoms include…

  • Irritability: Feeling easily annoyed or agitated, often over minor issues.
  • Anxiety: A feeling of worry, nervousness, or unease, typically about something with an uncertain outcome.
  • Insomnia: Difficulty falling asleep or staying asleep, leading to inadequate rest and fatigue.
  • Decreased appetite: A reduced desire to eat, potentially resulting in weight loss or nutritional deficiencies.
  • Mood swings: Rapid changes in mood, characterized by shifts between happiness, sadness, irritability, or anger.
  • Headaches: Pain in the head or upper neck region, which can range from mild discomfort to severe throbbing.
  • Sweating: Excessive perspiration, often accompanied by a feeling of warmth or clamminess.
  • Digestive issues: Symptoms such as nausea, vomiting, diarrhea, or stomach discomfort.
  • High blood pressure: Elevated blood pressure, which can increase the risk of heart disease, stroke, and other cardiovascular problems.

Quitting weed causes high blood pressure, as THC can have both short-term effects of increasing heart rate and blood pressure and long-term effects on cardiovascular health. However, it's important to note that these symptoms typically subside over time as the body detoxifies and returns to its baseline state. Seeking support from healthcare professionals or support groups can be beneficial for managing withdrawal symptoms and maintaining sobriety.

Edibles and Blood Pressure

While the research on the relationship between THC (the psychoactive component of marijuana) and blood pressure is limited, a 2017 study examined the effects of cannabidiol (CBD) on blood pressure. In this study, participants were given CBD in the form of edible pills. The results indicated that CBD helped lower resting blood pressure and reduce blood pressure spikes caused by stress and associated elevated heart rate. Although this study focused on CBD rather than THC, it suggests a potential association between cannabis compounds and blood pressure regulation. However, further research is necessary for a comprehensive understanding of the effects of edibles on blood pressure.


Can quitting weed raise blood pressure? In conclusion, the relationship between high blood pressure and quitting weed is a complex and evolving topic. While some studies suggest that marijuana may have the potential to lower blood pressure, the research is still limited and inconclusive. On the other hand, smoking any substance, including marijuana, can have negative effects on cardiovascular health and raise blood pressure.

If you are considering quitting weed, it is essential to monitor your blood pressure and consult with healthcare professionals for guidance. More research is needed to fully understand the effects of THC withdrawal blood pressure and the implications of quitting. Remember, health decisions should always be made in consultation with healthcare professionals who can provide personalized advice based on your individual circumstances.
