How can smoke cause headaches?

ANSWER

There are several ways that smoking is linked to headaches:

  • Nicotine in tobacco products. causes the blood vessels in your body to narrow. This reduces blood flow to your brain, which can trigger a migraine.
  • Carbon monoxide is also in tobacco products. If you're a smoker, you may have high levels in your blood and brain. Carbon monoxide can trigger headaches.
  • Sensitivity to smells. For some people, the smell that smoking gives off is enough to cause a headache or migraine. You can also have an allergy to cigarette smoke, which can trigger a headache when you're around it.
