Afe A E Fc A What Does Weed Do To Your Pupils

Whether you’re a fan of weed or you’ve never smoked it in your life, you probably know about some of the things that happen to you as a result. 

Maybe you have at least some understanding of how weed works. The chemical THC (tetrahydrocannabinol) moves through your bloodstream and interacts with your brain to cause a high. 

The effects of marijuana depend on the strain of marijuana and how much or often you use it. A big hit of a high-THC strain will affect you very differently than a bite of a pot cookie. 

What causes the red eyes? Why do some people experience cottonmouth or find it affects their sex life? What gives you the munchies? Fortunately, there is a lot of research to answer those questions.

Dopamine Floods Your Brain

Like most drugs, the high from cannabis comes from the neurotransmitter dopamine, which is part of our brain’s reward system. Dopamine is responsible for several things, including pleasure, memory, thinking, concentration, movement, coordination, and sensory and time perception

THC acts through cannabinoid receptors in the brain and body.  THC stimulates the release of dopamine in large amounts, causing you to feel euphoric. This is what makes you feel high when you use weed. It’s not only dopamine that is affected by weed. It also alters other receptors for neurotransmitters like GABA and serotonin, which change your mood. The high that happens depends on which neurotransmitters are affected.

Body Fluids Dry Up

Weed can temporarily dry up mucus membranes throughout the body, including in the vagina. Other mucus membranes in your body include your eyes and mouth, so you may find that dryness affects you in those areas as well, depending on the strain of weed and your reaction to it.

Your Blood Pressure Drops

Weed causes blood vessels across the body to dilate, which makes your blood pressure drop. This is most noticeable in the eyes. As your blood pressure falls, they look red, and your pupils can become dilated. This is what gives weed users the bloodshot appearance in the eyes after using cannabis. At the same time, breathing passages relax and open up, which adds to the feeling of relaxation and calm that some people feel when they’re high.

Your Senses Get More Intense

You might find that as well as the effects of a slower heart rate and the widening of your breathing passages, your senses can feel more acute. You might be able to notice different smells, touches, or other sensations that you might not normally notice, or experience them to a more intense level.

This is because, as well as triggering the release of dopamine, THC binds to brain receptors that are associated with your senses of smell and taste, which heightens their sensitivity. Along with the side effect of pupil dilation, a lot of your senses can become heightened for a short while. This is why THC affects your cognition and coordination when you’re very high, and why driving while high is a dangerous idea. It helps to buy from a legitimate weed store so you know what to expect from your high. 

Your Heart Rate Increases

Despite the fact that weed is used by lots of people to relax, what you might not know is that smoking weed is known to speed up your heart rate for up to three hours after you get high.  Your dilated blood vessels cause the muscles in your heart to work harder to pump blood. THC can make you more likely to experience anxiety and panic attacks, which make the heart beat rapidly. Although a quick heart rate is usually harmless, a racing heart rate can increase your chances of having a heart attack, especially when combined with the drop in blood pressure.

Your Sense Of Hunger Is Distorted

Even if you don’t smoke, you probably know about the munchies. Researchers and weed users have known for a long time that cannabis increases the appetite, and recently, science has begun to look into the reason. THC is responsible for most of the psychoactive effects associated with cannabis use including the high as well as increased appetite, known as the munchies. THC interacts with the neurons that are responsible for telling your body to stop eating. When you get high, these neurons start to signal that you’re actually really hungry. 

If you buy your weed from a weed store in Vernon or your local area, you can get a better idea of the kind of high you’re likely to experience.
