Does THC Raise Heart Rate
Yes, THC can raise heart rate. This effect is called tachycardia and usually begins within minutes after using THC. According to the American Heart Association, heart rate can increase by 20 to 50 beats per minute or more during this period. The increase is often most noticeable shortly after inhalation or ingestion.
Why THC Increases Heart Rate
THC interacts with the endocannabinoid system and can influence the autonomic nervous system. This may reduce blood pressure in some cases, causing the heart to beat faster to maintain blood flow. Individual responses vary based on dose, tolerance, method of use, and overall health.
What the Research Says
Studies show that THC can temporarily raise heart rate, especially in new or infrequent users. Long-term tolerance may reduce this effect over time. People with existing heart conditions should be cautious and consult a healthcare provider before using THC products.
