Edibles, a form of cannabis consumption, have gained popularity for their discreet nature and prolonged effects. A common concern is the potential for an elevated heart rate. Understanding how these products interact with the body can explain this physiological response.
How Edibles Affect the Body
When cannabis is consumed as an edible, it undergoes a distinct metabolic process compared to smoking or vaping. Tetrahydrocannabinol (THC), the primary psychoactive compound, is absorbed through the digestive system and transported to the liver. Here, liver enzymes convert delta-9 THC into 11-hydroxy-THC. This metabolite is potent and contributes to the unique experience of edibles.
The conversion into 11-hydroxy-THC results in a delayed onset of effects, typically ranging from 30 minutes to two hours. This slower absorption contrasts sharply with the almost immediate effects felt from inhaled cannabis. Once active, the effects of edibles can last significantly longer, often extending from four to twelve hours, with heightened intensity.
Understanding THC’s Cardiovascular Effects
The reason edibles can cause an increased heart rate lies in how THC interacts with the body’s endocannabinoid system. THC binds to cannabinoid 1 (CB1) receptors, found throughout the body, including within the cardiovascular system. This interaction can stimulate the sympathetic nervous system, often referred to as the “fight or flight” response.
Activation of the sympathetic nervous system leads to an elevation in heart rate, a condition known as tachycardia. The heart rate can increase by 20 to 50 beats per minute, potentially lasting for up to three hours after consumption. For most healthy individuals, this temporary increase is generally not harmful, though it can be alarming.
Factors Influencing Heart Rate Response
Several variables can influence an individual’s heart rate response to edibles. The dosage of THC is a factor; higher concentrations lead to more pronounced effects. Individual tolerance also plays a role, as those with less experience may experience a more significant cardiovascular response.
Pre-existing cardiovascular conditions, such as hypertension or arrhythmias, can heighten the risk of adverse reactions. For individuals with such conditions, the increase in heart rate and blood pressure caused by THC could exacerbate their health issues. Psychological factors, particularly anxiety levels, can also amplify the sensation of a racing heart, making the experience more uncomfortable. Co-consumption of other substances like caffeine or alcohol might interact with THC, potentially influencing the cardiovascular effects.
Responding to an Elevated Heart Rate
Experiencing an elevated heart rate after consuming edibles can be unsettling, but certain strategies can help manage the situation. Focusing on calming techniques, such as deep breathing exercises, can help alleviate anxiety and the perceived intensity of the heart rate. Moving to a quiet, familiar, and comfortable space can also contribute to a sense of safety and reduce panic.
Staying hydrated is beneficial, as dehydration can intensify some effects. Reassuring oneself that the effects are temporary and will pass is important, as panic can worsen the experience. Avoid consuming more edibles or other substances if an elevated heart rate occurs. If symptoms include persistent chest pain, extreme difficulty breathing, or prolonged severe anxiety, seeking immediate medical attention is a prudent step.
