Yes, marijuana (weed) can cause anxiety and panic attacks in some individuals. While many people use cannabis to relax or reduce stress, it can have the opposite effect in certain situations — especially when using high-potency strains that are rich in THC (tetrahydrocannabinol), the main psychoactive compound in marijuana.

Why does weed cause anxiety or panic in some people?

Cannabis affects the brain’s endocannabinoid system, which plays a role in mood, perception, and stress regulation. In some users, THC overstimulates areas of the brain like the amygdala, which is linked to fear and anxiety responses. This can lead to symptoms such as:

  • Racing heart or palpitations
  • Shortness of breath
  • Dizziness or lightheadedness
  • Intense worry or fear
  • Feeling “out of control” or dissociated

These symptoms may mimic or trigger a panic attack, especially in first-time users or those with a history of anxiety disorders.

Who is most at risk?

You may be more likely to experience anxiety or panic from marijuana if you:

  • Are new to cannabis use
  • Use high-THC or synthetic cannabis products
  • Have a personal or family history of anxiety, panic disorder, or other mental health conditions
  • Use cannabis in unfamiliar or stressful settings
  • Mix cannabis with alcohol or other substances

Can CBD help instead of THC?

Unlike THC, CBD (cannabidiol) is a non-psychoactive compound in cannabis that may have anti-anxiety effects. Some people report feeling calmer with CBD-only products. However, results can vary, and it’s best to consult a healthcare professional before using cannabis for anxiety.

What should I do if weed makes me anxious?

If you’ve experienced anxiety or panic after using cannabis:

  1. Stop using it and avoid high-THC strains.
  2. Practice grounding techniques, like deep breathing or focusing on your surroundings.
  3. Seek help from a mental health provider, especially if symptoms persist or interfere with daily life.
  4. Avoid using cannabis as a coping mechanism for stress or mental health concerns.
