Types of headaches
Headaches fall into groups. The main types are:
- Migraine: moderate to severe pain, often on one side. Nausea and light sensitivity may occur.
- Tension-type headache: mild to moderate pressure on both sides.
- Cluster headache: severe pain around one eye. Attacks last 15 minutes to 3 hours.
What research shows
Most studies on cannabis and headache include fewer than 100 people. Many lack a placebo group. A 2019 review found limited evidence. Some patients reported fewer migraines. The review noted that most studies had no control group.

One survey of 121 people with migraine found that 11% used cannabis. Those users had more headaches than non-users. Another study of 145 people found that cannabis reduced migraine frequency by 50% in some cases.
THC and CBD
THC and CBD are the two main compounds in cannabis. THC causes the high. CBD does not. Studies on headache often use products with both. The ratio varies. No ratio is proven best for headache.
THC may reduce pain in some people. CBD may reduce inflammation. But evidence for headache is weak.
Dosing
No standard dose for headache exists. Effects depend on the product, the person, and the headache type. A common approach for new users is to start with a low dose. Wait 2 hours. Then adjust. Smoking or vaping acts within minutes. Edibles take 30 to 120 minutes.
Risks and side effects
Cannabis can cause:
- Dizziness
- Dry mouth
- Impaired memory
- Fast heart rate
- Anxiety or paranoia
Frequent use can lead to rebound headaches. Cannabis use disorder affects about 1 in 10 users. That number rises to 1 in 6 for people who start before age 18.
Legal status in the US
Cannabis is illegal under federal law. It is Schedule I. As of 2024, 24 states and Washington, D.C. allow recreational use. 38 states allow medical use. State laws differ on possession limits and product types. Check your state rules.
Talking to a doctor
Ask your doctor about cannabis for headache. Bring your headache history. Mention any drugs you take. Cannabis can interact with blood thinners, antidepressants, and seizure medicines. A doctor can help you weigh benefits and risks.
