Marijuana makes your eyes red because it opens up the blood vessels in your eyes, making them look bloated and puffy. This happens because of a special part in marijuana called THC that affects your body in different ways. Some people use marijuana for medical reasons to help with their health problems, like high blood pressure or pain. But it can also cause some side effects, like making your eyes look red and puffy. The more THC there is in the marijuana, the stronger these effects will be. Everyone's body is different, so not everyone will have the same reaction to marijuana. Read from source...

1. The title is misleading because it implies that red eyes are a consequence of vasodilation, which is not entirely true. Red eyes can also be caused by other factors, such as allergies, dryness, or infection. The article should have clarified this point at the beginning to avoid confusion and provide a more accurate representation of the topic.
2. The author uses terms like "smoke irritation" without providing any scientific evidence or explanation for how smoke could cause red eyes. This is an example of a weak argument that lacks credibility and substance.
3. The author claims that many people are not aware of the physiological mechanism behind red eyes, but this statement is vague and unsubstantiated. How does the author know what most people are aware of? What evidence do they have to support this claim? This is another example of an emotional appeal fallacy that tries to persuade readers without providing any factual basis for their argument.
4. The mention of medical practitioners prescribing cannabis-based medications to patients suffering from various conditions is irrelevant and does not contribute to the main point of the article, which is about red eyes and vasodilation. This information should have been removed or placed in a separate section to avoid distracting readers from the main topic.
5. The author uses terms like "risks involved are most times underestimated" without providing any data or statistics to support this claim. This is another example of an irrational argument that relies on emotional appeal rather than logical reasoning and evidence-based facts.
6. The explanation of what makes cannabis a vasodilator and the role of THC in inducing these effects is somewhat accurate, but it could have been more detailed and comprehensive to provide readers with a better understanding of the topic. For example, the author could have mentioned other cannabinoids that may also contribute to vasodilation, such as CBD or CBN, and how they interact with the endocannabinoid system in the human body.
7. The article ends abruptly without providing any conclusion or summary of the main points discussed. This leaves readers feeling unsatisfied and confused about what the author was trying to convey. A more effective way to conclude the article would be to restate the thesis statement, summarize the key arguments, and provide some recommendations for further research or action.
