Red Eyes and How to Prevent It: The Cannabis Effect


Posted on March 14th, 2023 to Blog Post by

Marijuana is well-known for its psychoactive effects, including euphoria, relaxation, and altered perception. But it is also known to cause red eyes, which can be an uncomfortable and embarrassing side effect.

Today, we will explore the reasons why smoking cannabis gives you red eyes and how you can prevent it:

Why Does Cannabis Cause Red Eyes?

Red eyes are a common side effect of smoking marijuana. This is because THC, the main psychoactive compound in cannabis, causes blood vessels in the eyes to expand, leading to increased blood flow and redness. THC also lowers blood pressure, which can contribute to red eyes.

Additionally, smoking anything can irritate the eyes and cause them to become red and dry. Cannabis smoke contains many of the same irritants as tobacco smoke, including tar, carbon monoxide, and other toxins. These irritants can cause inflammation in the eyes and contribute to redness.

Preventing Red Eyes

While red eyes are a common side effect of smoking marijuana, there are several ways to prevent or reduce their severity:

1. Use Eye Drops

One of the easiest ways to combat red eyes is to use eye drops. Over-the-counter eye drops can help reduce redness and dryness in the eyes. However, it is important to use eye drops sparingly and only as directed, as overuse can actually make the problem worse.

2. Stay Hydrated

Drinking plenty of water can help keep your eyes hydrated and prevent them from becoming dry and irritated. Dehydration can exacerbate red eyes, so it is important to stay hydrated while smoking marijuana.

3. Limit Your Intake

If red eyes are a persistent problem for you, consider limiting your intake of marijuana. Smoking less or using a lower-THC strain can help reduce the severity of red eyes.

4. Use a Vaporizer

Using a vaporizer instead of smoking can also help reduce the severity of red eyes. Vaporizers heat cannabis to a temperature that is high enough to release THC and other compounds but low enough to avoid combustion. This produces a vapor that is less irritating to the eyes and, as a bonus, the lungs.

5. Take Breaks

Taking regular breaks while smoking can also help reduce the severity of red eyes. This allows your body to process THC and other compounds more efficiently, which can reduce the overall impact on your eyes and body.

Red eyes are a common side effect of smoking marijuana, but they can be prevented or reduced with a few simple steps. Using eye drops, staying hydrated, limiting your intake, using a vaporizer, and taking breaks can all help reduce the severity of red eyes. If you experience persistent redness or discomfort, it is important to talk to your doctor, as this could be a sign of a more serious underlying condition.


Overall, smoking cannabis can be a fun and enjoyable experience, but it is important to be mindful of the potential side effects and take steps to mitigate them. By following these tips and using cannabis responsibly, you can enjoy the many benefits of this amazing plant without experiencing uncomfortable side effects like red eyes!
