CBD & Heart Palpitations: What the Research Says - VO Inc

According to some sources, there's a link between CBD and heart palpitations–but is it real? Can this cannabis-derived compound indeed affect your heart rate or rhythm? 

Unlike THC, the well-known culprit for causing heart rates to skyrocket, CBD is often associated with relaxation and relief. For many, this makes the link between CBD and heart palpitations conflicting. Luckily, science generally confirms that CBD is safe for heart health. 

Want the full picture? Let’s dig into the research to unveil the truth about CBD and its potential effects on heart palpitations.

Key Takeaways

  • THC, not CBD, is primarily responsible for causing heart palpitations by relaxing blood vessels and increasing heart rate.
  • Extensive research discredits the idea that CBD converts to THC in the stomach, debunking concerns about THC-like effects from CBD consumption.
  • Individual reactions to CBD can vary, influenced by factors such as consumption method, concurrent substance use, and unique body chemistry.

Understanding CBD and the Cardiovascular Connection

To comprehend the possible relationship between CBD and heart palpitations, we first need to grasp the intricate ties between the cardiovascular system and the endocannabinoid system (ECS). The cardiovascular system acts as the body’s essential transportation network, carrying vital nutrients through veins and arteries to sustain every cell.

Interestingly, research has found that the ECS is closely intertwined with this system. Endocannabinoids (the body’s natural cannabinoids) like anandamide and 2-AG, interact with ECS receptors (CB1 and CB2) spread throughout the body. Sources show that these endocannabinoids are produced by the heart

These interactions play a critical role in supporting the immune system and maintaining a delicate balance, a cornerstone of good health.

So, it's not far fetched to say that CBD could have an impact on the heart or circulatory functions. But, without substantial evidence, it seems premature to say that CBD can cause heart palpitations. Instead, THC is the more likely cause:

The THC Factor and Heart Palpitations

When we talk about heart palpitations associated with cannabis consumption, THC takes the spotlight. THC, the psychoactive compound prevalent in cannabis, has the knack for causing blood vessels to relax and dilate, resulting in a surge of heart rate. While this effect is typically not alarming for healthy individuals, it can pose risks for those with underlying heart conditions.

On the flip side, CBD, another significant cannabinoid in cannabis, follows a different script. CBD, renowned for its antioxidant and anti-inflammatory properties, doesn’t exert the same influence on the cardiovascular system. In fact, it can counteract some of THC’s adverse effects, such as anxiety and rapid heartbeat.

CBD Doesn't Cause Heart Palpitations: Debunking the CBD-to-THC Conversion Myth

So, why do some sources claim that CBD can cause heart palpitations? Mostly, it's based on a misunderstanding. 

A persistent myth suggests that CBD can transform into THC in the stomach, potentially causing THC-like symptoms, including heart palpitations. This is based on one widely disputed study that found that CBD converted to THC in a simulated gastric acid material. 

However, extensive research has debunked this claim. When exposed to natural digestive juices, CBD maintains its integrity and remains CBD, with no signs of transforming into THC.

If you’ve been worried about CBD triggering THC-like effects, the evidence indicates that such concerns may be unfounded.

Don't Forget: Individual Reactions Vary

Understanding CBD's impact on heart palpitations isn't a one-size-fits-all scenario. Individuals react differently to CBD, and various factors can influence its effects. 

One such factor is the mode of consumption: tinctures act swiftly through the mouth's mucus membranes, while edibles take a more leisurely route through the digestive system. 

CBD is also biphasic, meaning it’s effects are much different at higher doses than they are at lower doses. More specifically, at low doses CBD is stimulating. At higher doses, it may have a more profound, sedating effects. Every person has a unique dosage threshold, so dosing greatly affects the CBD experience and any CBD side effects you may experience. 

Furthermore, other elements, like the simultaneous consumption of caffeine or specific medications, may contribute to variations in heart rate. Appreciating this complexity is crucial as we navigate the realm of CBD and heart health.
