An Expert Explains What Happens To Your Body When You Smoke Weed
ItвЂ™s not just bloodshot eyes and munchies.
Whether you’re an avid stoner or never touched a joint in your life, chances are you’re familiar with the things that happen when you smoke weed. The drowsiness, the giggles, the sudden deep desire to discuss eighth grade philosophy, and other such overt symptoms are all the result of hidden processes going on in your body when you get high.
You probably have at least a vague understanding of how weed works: The chemical tetrahydrocannabinol, better known as THC, zips through your bloodstream after ingestion and interacts with parts of your brain like the hippocampus and orbitofrontal cortex to cause a high. It’s more complicated than that, of course, but the general concept isn’t difficult to grasp (unless you’ve had one too many pot brownies).
вЂњThe effects of marijuana depend in part on the strain of marijuana and whether the person is a chronic user or not,” Dr. Keith Heinzerling M.D., addiction medicine specialist at Providence Saint John’s Health Center, tells Bustle. A giant hit of a high-THC strain will affect you very differently than if you have a tiny nibble on a pot cookie.
But what causes the red eyes? Why do some people experience cotton mouth or find it affects their sex life? Perhaps most importantly, what’s the deal with the munchies? Fortunately for the curious вЂ” or those who prefer to know what’s going on inside their bodies вЂ” there’s plenty of research devoted to answering these questions.
1. Dopamine Floods Your Brain
Like most drugs, cannabis’s high comes from the neurotransmitter dopamine, which is associated with our brain’s reward system; as noted by a study in the National Institute of Drug Abuse, dopamine is responsible for “pleasure, memory, thinking, concentration, movement, coordination, and sensory and time perception.”
“THC acts through cannabinoid receptors in the brain and body,” Heinzerling says. Using these receptors, THC stimulates the release of dopamine in large amounts, causing feelings of euphoria. It’s this reaction that’s responsible for the “high” you feel after using cannabis. Heinzerling adds that dopamine isn’t the only thing that’s affected by weed; it also alters other receptors for neurotransmitters like GABA and serotonin, which influence your mood. Your particular flavor of high depends on which neurotransmitters are impacted.
2. Body Fluids Dry Up
Talk about a mood killer. A study published in Journal Of Sexual Medicine in 2010 found that weed can temporarily dry up mucus membranes throughout your body, including your vagina вЂ” hence the term “cotton vagina” that’s been, well, cottoning on in some circles. Other mucus membranes in your body include your eyes and mouth, so you may feel dryness effects in those regions too, depending on the strain of cannabis and your individual reactions to them.
3. Your Blood Pressure Drops
Weed causes blood vessels across your body to dilate, creating a drop in blood pressure. This is most apparent in your eyes; as your blood vessels expand, they appear red, and your pupils may become dilated вЂ” this is what gives people the “bloodshot” look in their eyes after using cannabis. Simultaneously, breathing passages relax and open up, which contributes to the feeling of relaxation and calm that some people experience during a high.
4. Your Senses Get More Intense
You might notice that in addition to the depressive effects of a slower heart rate and the widening of your breathing passages, your senses also seem more acute вЂ” you may notice different smells, touches, or other sensations that you might not normally note, or experience them in more intense degrees.
This is because, in addition to triggering the release of dopamine, THC binds to brain receptors associated with your senses of smell and taste, which has been shown to heighten their sensitivity. Combined with the side effect of pupil dilation, many of your senses can become temporarily heightened. This is the reason that THC affects your cognition and coordination when you’re very high, Keinzrling says вЂ“В and it’s why driving while stoned is a bad idea.
5. Your Heart Rate Increases
Despite the fact that weed is used for many as a relaxant, what you may not realize is that smoking weed is known to speed up your heart rate for up to three hours after getting high; the dilation of your blood vessels causes the muscles in your heart to work harder to pump blood. Heinzerling says THC can also heighten your risk of anxiety and panic attacks, which make the heart pound rapidly. Although a quick heart rate is often harmless, the National Institute on Drug Abuse notes that a racing heart rate can increase your chances of having a heart attack, especially when combined with the drop in blood pressure.
6. Your Sense Of Hunger Is Distorted
Even if you don’t smoke, you’re no doubt familiar with the munchies. Researchers (and stoners) have long known that cannabis increases appetite, and recently, science has begun to shed light on the reason. “THC is responsible for most of the psychoactive effects associated with cannabis use including the high as well as increased appetite (вЂњmunchies”),” Heinzerling says. According to a 2015 study published in Nature Neuroscience, THC “flips a switch,” so to speak, on the neurons that were previously responsible for telling your body to stop eating. When you get high, these neurons begin signaling that you’re actually starving вЂ” and suddenly you find yourself in the Taco Bell parking lot surrounded by what used to be seven burritos.

Best Tips To Hide That You’re High
Hiding your high can be a daunting experience, but it does not have to be. Just remember there is no neon light behind your head advertising you just toked. Plus, a lot of accessories can help you hide the smell, if not the “look” of being freshly stoned. Here are our tips on hiding your high.
No matter how accepted cannabis is becoming, every stoner knows the experience; you are caught somewhere, for some reason, high.
Most experienced stoners have figured out a way to handle this situation. But what if you are a relative newbie?
How does one manage and conquer this scenario? Read on for our best tips.
DON’T GET HIGH AROUND STRANGERS
Your eyes turn bright red at a single puff. You cannot control the giggles. You are paranoid about the martians who have just landed next door. Or you otherwise exhibit stereotypical stoner behaviour every time you toke. If this is you, think seriously about the strategy of evasive procedures.
In general, it is a good idea for novices to experiment around friends. Getting high by yourself is a lonely experience. Try to be in a group of people that you know and trust during your first few toking sessions.
That way, any weed-induced flubs will be dealt with appropriately. Getting high with strangers can often combine the jitters of meeting new people with the paranoia of being a new smoker. Unless you thrive in spontaneous circumstances, this situation is best avoided.
PREPARE WELL BEFORE YOU TOKE
Cannabis consumption results in certain telltale signs. If you prepare beforehand, you can be prepared to act at a moment’s notice. Stocking up on sunglasses, eye drops, gum, and even a spray-on deodoriser is a smart idea. Sploofs – a kind of filter that blocks smoke (and odour) from dissipating – can also help.
You might also consider showering to remove the smell of smoke from your body and hair.
Changing your clothes is another way to get rid of the lingering dank scent. Even if you don’t go to these extremes, remember to wash your hands and perhaps brush your teeth. Handling cannabis can leave a strong smell.
Having candles and air fresheners in stock is always a good idea.
Ok, this is a hard one if you are ravenous, glued to the couch, or cannot contain giggle fits. Stay clear from talking about the euphoria you feel. That one is a dead giveaway. If you must be social with non-smokers after you indulge, don’t attempt this as a newbie. You will become a bundle of nerves. Once you get used to the feeling, you will be better able to interact with “civilians” and “pass”.
In the meantime? Keep conversations short and sweet. Your high won’t last very long. Get back to them later.
Do try to be around others who at least tolerate cannabis consumption. The silly goofs you might engage in will be forgiven faster. In many cases, your friends won’t care if you’re acting a little stoney.
Don’t engage in heated and emotional conversations. Let it go until you are more grounded and sober. And most certainly, do not fidget or “act guilty.” Chances are, most people won’t notice. Don’t tip them off.
HAVE A PREPARED HIDING PLACE
There is nothing worse than having anti-cannabis in-laws drop by right after a bong session. Or worse. Especially if you live in a less-than-weed-friendly jurisdiction, it is highly recommended that you have a convenient, easy-to-reach hiding place. This includes the weed itself, plus all accessories. Keep your cannabis in a well-sealed environment. This is one way to preserve its potency. But it is also a good idea if you are conscious about the smell. If you use a bong or other equipment, keep them clean.
DON’T WAX PHILOSOPHICAL OVER THE FRIDGE
Remove yourself from temptations you will regret later. This includes keeping large amounts of “binge-perfect” food in the fridge, or waxing philosophical over any topic. With anyone.
If you know you tend to get the munchies, prepare ahead of time by only having healthy snacks within reach.
And while your divergent thoughts might be fascinating to you, try not to overshare them. Write them down and come back to them later (when not stoned). You will be glad you did.
Being among non-stoners while high can be a disconcerting experience. Here are a few tips for removing the evidence and covering your tracks.
