Does CBD Actually Give Headaches As One Of The Side Effect?

Since everyone has unique body chemistry, there could be some people who react in a way that causes headaches or allergic reactions.

CBD is a cannabinoid that’s naturally found in the cannabis or hemp plant providing nutrients to the endocannabinoid system (ECS).

The ECS has a primary function is to regulate balance and homeostasis throughout the entire body.

While there are four basic types of headaches (migraine, tension, sinus, & cluster) there are up to several dozens of different types of headaches and various potential combinations of headaches

The actual cause of headaches might be a little more complex than taking a pure and clean high-quality CBD product from a trusted brand.

If you find yourself consistently getting headaches, directly after taking CBD, it might be several potential other possibilities.

Potential reasons why your CBD might give you a headache include.

  • It’s a contaminated full-spectrum oil and contains the a higher amounts of psychoactive THC molecule than the label says — this is why it’s alway important to double check the lab test results on the Certificate Of Analysis (COA) for the CBD product your about to purchase an regularly use.
  • It’s a purified CBD isolate and doesn’t have any other beneficial cannabinoid to trigger the entourage effect.
  • You didn’t take enough of a quality CBD oil brand – find the best dosage that work for you by calculating how much CBD is in each drop of CBD here and slowly increasing your dose until you achieve the desired results.
  • You took too much of a quality or low quality brand.
  • The low quality method the CBD oil was extracted might still contain impurities or left over extraction solvent.
  • You’re smoking CBD flower, vape cartridge, or eLiquid and the smoke (or nicotine) is triggering issues.
  • CBD is interacting with your other medication you’re taking. Check CBD drug interactions here.
  • You’re not drinking enough water after taking CBD and you’re moderately dehydrated.
  • You might have an allergy to CBD.
  • You’re taking a synthetic CBD.
  • CBD wears off and you need to take more.

CBD and other cannabinoids typically don’t cause headaches, nor are headaches a verified side effect.

Although it’s rare, there are people who are allergic to CBD and other cannabinoids.

According to the journal of Cannabis And Cannabinoid Research, a cannabinoid deficiency can be associated with headaches that transform into migraines.

CBD safety and effects research doesn’t specifically list headaches as a side effect of CBD, however, hypertension or lightheadedness might contribute to the reason why you’re getting a headache after taking CBD.

When taking too much CBD during the daytime or at work, higher CBD doses can make you sleepy, thus triggering irritability or even anger.

Can CBD Make Headache Worse?

However, some reports suggest when you take too much CBD, some unpleasant side effects can crop up and potentially cause what appears to be a headache.

After consuming a large dosage of CBD, another set of effects are triggered into action.

Due to the biphasic nature of CBD, at a lower dose, you can expect to have CBD wake you up and smooth out your day.

Whereas, when you take a higher dose, CBD produces more sedative effects.

If you’re taking a larger dose at the beginning of your day, you might not necessarily be experiencing a “headache” so much as you might be experiencing the sedative effects.

Feeling excessively sleeping at the beginning of the day, and then attempting to function at a high level, can cause stress and tension — when you actually are wanting to just roll over and go to sleep.

There is definitely some pain/stress in forcing yourself to stay awake when every part of you is just wanting to lay your head down and go to sleep.
