Yes, cannabis can cause anxiety, and the effects can vary widely from person to person depending on multiple factors such as dosage, THC content, frequency of use, and individual mental health history.
How cannabis affects anxiety
Cannabis interacts with the brain’s endocannabinoid system, which plays a role in mood regulation, stress response, and emotional balance. While some people experience temporary relaxation, others may feel heightened anxiety. This is especially true when cannabis contains high levels of THC, the psychoactive compound responsible for the “high.”
Common anxiety-related symptoms caused by cannabis
People who experience anxiety from cannabis may notice:
- Increased heart rate or palpitations
- Racing or intrusive thoughts
- Feelings of fear, panic, or loss of control
- Restlessness or difficulty relaxing
- Paranoia or heightened alertness
These symptoms can appear shortly after use and may last from minutes to several hours, depending on the method of consumption.
Factors that increase the risk of anxiety
Cannabis-related anxiety is more likely when:
- THC potency is high, especially in concentrates or strong edibles
- Large doses are consumed, intentionally or unintentionally
- Edibles are used, as their delayed onset can lead to overconsumption
- The user has a history of anxiety, panic disorder, or trauma
- Cannabis is used in stressful or unfamiliar environments
THC vs. CBD and anxiety
- THC can increase anxiety at moderate to high doses.
- CBD (cannabidiol) is non-intoxicating and may have calming effects for some individuals.
Products with a high THC-to-CBD ratio are more likely to cause anxiety symptoms.
Can cannabis cause long-term anxiety?
In some cases, frequent or heavy cannabis use may contribute to ongoing anxiety, especially in individuals who are already vulnerable. Cannabis can also mask symptoms temporarily, which may delay proper treatment.
When to seek help
If anxiety persists after cannabis use, interferes with daily life, or includes panic attacks, it’s important to seek support from a mental health professional. Anxiety is treatable, and evidence-based therapies can help manage symptoms safely and effectively.
Key takeaway
Cannabis can both trigger and worsen anxiety, particularly when high-THC products are involved. Individual reactions vary, but understanding dosage, potency, and personal mental health factors is essential. For lasting anxiety concerns, professional guidance is recommended.
