Do your eyes turn red by using legal weed?

Modified on: 19/04/2024


Although hemp properties are increasingly appreciated, confusion still reigns today regarding illegal marijuana and CBD cannabis.

The various effects of products containing THC are very different from those of legal weed, which are relatively high in CBD and are even considered therapeutic.

Speaking of side effects, in this article, we want to focus on red eyes.

Many people ask: “Does CBD weed make your eyes red, or is this embarrassing effect solely due to illegal hemp taking?”

Here you will find the answer and many other useful and interesting information, including those with regards of CBD intake.

Why does marijuana cause red eyes?

When a person uses illegal cannabis, unlike CBD buds, effects on behaviour and on the face are undeniable: continuous laughter, immeasurable appetite and…. red eyes!

In particular, the appearance of red eyes after smoking an illegal weed spliff, is a phenomenon that many would like to avoid. It attracts the attention and judgment of the surrounding people.

But why are the eyes bloodied after smoking?

Why does marijuana cause red eyes?

There are two main reasons: one is related to the body’s reactions to ingested substances and smoke irritation.

  • Low pressure: taking marijuana with high or medium THC levels can lead to lower blood pressure. The capillaries spread, so the amount of blood flowing through them is more significant, and the eyes appear resolutely red and look inflamed.
  • Irritation from smoking. Besides the capillary’s extension, the redness of the eyes may also depend on excessive sensitivity to smoke. When a little smoke reaches the part of the eyes, it can become irritating, causing a burning sensation and a lot of tearing.

In the first case, the symptom only disappears after the body has eliminated the most significant amount of THC. Still, in the second case, it only takes a few minutes for the eyes to return to normal.

However, to avoid this problem, there are solutions.

What is the CBD cannabis effect?

At this point, you’ll probably want to know if taking CBD cannabis can also cause the red-eye phenomenon.

The answer is no!

With a very low THC content, legal weed do not have all the side effects that occur in the body of illegal marijuana users.

No red eyes, no substance dependence, no psychotropic effects, paranoia, or other deleterious alterations in the mental state.

On the contrary, legal cannabis with high CBD levels has beneficial effects on the body in different ways.

Some people use it as a remedy for sleep disorders (insomnia), who take it to relax while some people use the miraculous effects of CBD to relieve symptoms such as nausea, headache or joint pain.

The soothing and analgesic properties of CBD in hemp and its derivatives (such as CBD oil, legal hash, etc.) are also highly appreciated by women in the relative phase of the menstrual cycle or to soothe symptoms of the pre-menstruation syndrome.

However, suppose you are reading this article because you currently have red eyes or you had to attend some special events in the past with eyes that did not want to return to their original color. In that case, it is likely that you also want to know some other remedy.

We will talk about that in the next paragraph.

Red eyes …? find out how to solve theproblem.

Red eyes …? find out how to solve this insidious problem.

To eliminate the redness of the eyes caused by marijuana with high THC content — which we remind you to be illegal — there are mainly three possibilities.

The first way that comes to someone’s mind is to wear sunglasses. However, as it is inappropriate in so many situations, you should use it as a backup method if the two next ones you are going to read about, should not work.

The first thing you should try is to use good eye drops.

Today, there are specific products that can solve eye redness quickly. These are eye drops that can restore the whites of the eyes in a few drops.

On the other hand, the second solution is hydration. If you drink a lot of water, the dry feeling that accompanies the red eyes is relieved, but not only that, it should also speed up the process of eliminating THC circulating in the body.

Of course, the success of the mixture between these two methods is subjective. It depends on both your body and the amount of THC you introduced with illegal weed.

If the results are slow, opt for glasses.
