Can cannabis cause heart palpitations?

What do cannabis-related palpitations feel like?

People often describe:

• A fast or pounding heartbeat
• Fluttering in the chest
• Irregular or skipped beats
• Strong awareness of the heartbeat even while resting

These sensations may start within minutes when smoking or vaping, or within 30 to 90 minutes when consuming edibles.

Why does cannabis trigger palpitations?

THC affects the body in several ways that can lead to palpitations:

• It stimulates the nervous system and increases alertness
• It raises heart rate temporarily
• It affects blood vessel function and blood pressure
• It can trigger anxiety or panic, which makes palpitations feel stronger

How long do the effects last?

• Smoking or vaping: typically 1 to 3 hours
• Edibles: can last 4 to 8 hours or longer

Palpitations usually fade as the effects of THC wear off.

Is it dangerous?

For most healthy individuals, cannabis-related palpitations are temporary and not harmful.

However, the risk may be higher if you:

• Have a heart condition such as Arrhythmia
• Have high blood pressure or other cardiovascular issues
• Combine cannabis with stimulants like caffeine or certain medications

When should you seek medical help?

Seek immediate medical attention if you experience:

• Chest pain or pressure
• Shortness of breath
• Fainting or severe dizziness
• A prolonged or irregular heartbeat

How to reduce the risk

To lower the chances of palpitations:

• Start with low THC doses
• Avoid high-potency cannabis products
• Stay hydrated
• Use cannabis in a calm and comfortable setting
• Avoid mixing it with alcohol or stimulants

Bottom line

Cannabis can cause heart palpitations due to its effects on heart rate and the nervous system. While usually temporary, frequent or severe symptoms should be evaluated by a healthcare professional.
