A pleasant cigar-smoking experience can quickly turn sour when an unexpected headache follows. For some, the experience of a ‘headache after smoking a cigar‘ is a perplexing and discomforting issue, raising concerns about their health and overall enjoyment of cigars.

Causes of Post Cigar Headaches

One of the primary causes of a headache following a cigar session is nicotine. Cigars are rich in nicotine, a stimulant that has profound effects on the vascular system. When inhaled or absorbed through the mouth’s lining, nicotine can cause blood vessels to constrict. This sudden constriction of vessels within the brain can result in a headache.

Carbon Monoxide

Another potential cause is carbon monoxide, a byproduct of burning tobacco. Carbon monoxide displaces oxygen in your bloodstream, depriving your brain of much-needed oxygen, which can cause headaches. The cigar’s size, how long you smoke it, and the environment can all affect the carbon monoxide levels you’re exposed to.


One cannot overlook the effects of dehydration. Cigars can cause dry mouth and subsequently lead to dehydration if not offset by regular fluid intake. As our brains are largely made up of water, dehydration can lead to headaches.

Furthermore, poorly made cigars often contain chemicals and additives, which can lead to headaches. This is why it’s essential to invest in high-quality, all-natural cigars from trusted manufacturers.

How to Prevent a Cigar Headache

So, how can you prevent these headaches? Firstly, make sure you’re properly hydrated before, during, and after your cigar smoking session. Water can help to mitigate the dehydrating effects of nicotine and carbon monoxide.

Secondly, eat a good meal before smoking a cigar. Having food in your system slows the absorption of nicotine, reducing the chance of blood vessel constriction and subsequent headaches. Pairing your cigar with a non-alcoholic beverage can also help to slow nicotine absorption.

Thirdly, smoke in a well-ventilated area to reduce your exposure to carbon monoxide. Smoking in a confined space may increase the concentration of carbon monoxide, contributing to headaches.

Lastly, pace yourself. The faster you smoke, the higher your exposure to nicotine and carbon monoxide. Slow, measured puffs can lead to a more enjoyable and headache-free experience.

However, if you still experience headaches after following these prevention tips, it may be time to consult a healthcare professional. Regular headaches after smoking cigars could be a sign of an underlying health condition that needs to be addressed.

Bottom Line

In conclusion, while headaches after smoking cigars can indeed be an unpleasant surprise, they are usually a result of nicotine and carbon monoxide exposure, dehydration, and the quality of the cigar. By implementing preventative measures such as proper hydration, eating a meal beforehand, smoking in a well-ventilated area, and pacing your smoking, you can significantly reduce the chances of encountering this issue. Remember, if headaches persist, it’s important to seek medical advice.

Smoking cigars can be an enjoyable experience when done responsibly. Being aware of the potential pitfalls and taking steps to mitigate them can help to ensure that your cigar-smoking sessions remain pleasurable and headache-free.
