How Long Does Cannabis-Induced Anxiety Last?

Cannabis is widely used for relaxation, pain relief, and recreation—but for some people, it can trigger anxiety, panic, or paranoia instead. If you’re experiencing this, one of the first questions that comes up is simple and urgent: how long does cannabis-induced anxiety last?

What Is Cannabis-Induced Anxiety?

Cannabis-induced anxiety refers to feelings of nervousness, panic, racing thoughts, fear, or paranoia that occur during or after using cannabis, particularly THC-dominant products.

It may include:

• Rapid heart rate
• Shortness of breath
• Feeling “out of control” or impending doom
• Restlessness or agitation
• Trouble concentrating

While uncomfortable, cannabis-induced anxiety is usually temporary and not dangerous for otherwise healthy individuals.

How Long Does Cannabis-Induced Anxiety Typically Last?

Short Answer

For most people, cannabis-induced anxiety lasts between 30 minutes and 6 hours, depending on several factors.

Typical Duration by Consumption Method

Method	Onset	Anxiety Duration
Smoking or vaping	5–15 minutes	1–4 hours
Edibles	30–90 minutes	4–12 hours (sometimes longer)
Concentrates (dabs)	5–10 minutes	2–6 hours

Key takeaway: Anxiety usually fades as THC levels decline in the body.

Cannabis anxiety duration isn’t the same for everyone. Several variables influence how intense and long-lasting symptoms may be.

1. THC Dose and Potency

• High-THC strains and concentrates are the most common trigger
• Edibles can cause stronger, longer-lasting anxiety due to delayed absorption

2. Method of Use

• Edibles often lead to prolonged anxiety because THC is metabolized differently
• Inhaled cannabis typically wears off faster

3. Individual Sensitivity

• New or infrequent users are more prone to anxiety
• People with a history of anxiety or panic disorders may experience stronger symptoms

4. Environment and Mindset

• Stressful settings, unfamiliar surroundings, or negative expectations can intensify anxiety
• Being tired, dehydrated, or hungry can also worsen symptoms

5. CBD Content

• CBD may reduce anxiety, while THC may increase it
• Products with little or no CBD are more likely to trigger anxious reactions

Can Cannabis Anxiety Last Into the Next Day?

In most cases, no—but some people report lingering effects.

Possible Next-Day Effects

• Mental fog
• Fatigue
• Mild anxiety or unease
• Disrupted sleep

These symptoms usually resolve within 24 hours. Persistent anxiety beyond that timeframe may be related to underlying anxiety, not the cannabis itself.

How to Calm Cannabis-Induced Anxiety Safely

If you’re experiencing anxiety from cannabis, these strategies may help:

Immediate Relief Tips

• Remind yourself it’s temporary
• Sit or lie down in a quiet, familiar space
• Take slow, deep breaths (4 seconds in, 6 seconds out)
• Drink water or herbal tea
• Avoid caffeine or more cannabis

What May Help Over Time

• Eating a light snack
• Watching or listening to something calming
• Sleeping it off

Avoid alcohol or other substances to “counteract” the effects—they can worsen anxiety.

When to Seek Medical Help

Seek medical attention if:

• Chest pain or fainting occurs
• Anxiety becomes overwhelming or unmanageable
• Symptoms last longer than 24–48 hours
• There’s confusion, vomiting, or severe agitation

While cannabis anxiety is rarely dangerous, it’s always okay to seek help if you feel unsafe.

How to Prevent Cannabis-Induced Anxiety in the Future

• Choose low-THC or THC:CBD balanced products
• Start with a very small dose
• Avoid edibles if you’re sensitive to THC
• Use cannabis in a calm, familiar environment
• Avoid use when already stressed or anxious
