Why Does My Weed Smell Like Poop?

And other, Bodily Function, FAQ

Why do your feces and sweat smell like weed? This is an embarrassing question that you likely would not want to ask either your doctor or friends. But, according to Google, people search for answers to this question hundred of times each month. As a service to my reader, Ganjashark will attempt to answer the following crucial questions that you may have; but are afraid to ask.

  • Why does my poop smell like weed?
  • Why do my armpits smell like weed?

See A Doctor If you Have Questions- I am somewhat joking about the importance of the above questions. The above questions, other than curiosity’s sake, aren’t usually that crucial. However, any change in your bowel habits or even your sweat smelling different can signal a medical problem. For example, according to AARP, obnoxious body order can indicate a serious health condition. So, if in doubt, see a doctor if you are worried about any of the above issues.

Why Does My Poop Smell Like Weed? AKA Weed Shits

The most likely reason for your poop smelling like weed is because of edibles and simple digestion. Of course, marijuana edibles, like any food, is digested. However, depending upon how it is made, some food doesn’t digest as well. Also, some parts of the food are unable to be digested at all. When you eat something, the food will have to get digested by going through your intestines. Some marijuana remnants will likely remain in your poop, which results in the weed smell.


You are maybe more familiar with this happening in other situations. For example, if you don’t spit out the seeds while eating a watermelon, you will often find watermelon seeds in your poop. Additionally, after a heavy drinking night, you will also have a stench of alcohol after doing a number two.

Typically, this will occur if you eat either a large number of edibles or if the edibles recipe is not done correctly. Cannabutter is used extensively to make edibles. When done well, the cannabis will be smooth, and, other than the smell, you will likely not even know that the brownie you are eating will have you feeling suitable for a few hours. However, suppose the edibles are not cooked or prepared correctly. In that case, the cannabis smell will likely occur when you are reliving yourself. So, just like you will see seeds, if you accidentally end up swallowing some seeds while enjoying some sweet watermelon, your body may be affected by improperly prepared marijuana edibles.

Why Does My Armpits Smell Like Weed?

As you most likely observed, your weed armpits smelling like weed is caused by sweating. So, I will go over general sweating and not just ganja smelling armpits. Many marijuana smokers wonder why their sweat smells like cannabis. Marijuana smelling armpits is embarrassing, and it also could get you trouble at work, school, etc. To understand why this is happening, you first should understand precisely what sweat is and what causes it to smell.

Your sweat itself does not have any smell. Your skin though does contain billions and billions of microbes or bacteria that interact with your perspiration. This foul smell is caused by bacteria on your skin that is rapidly multiplying with bacteria resulting in the sweat breaking down into acids, which caused the nasty smell. Body order commonly occurs in the following areas:

● Hair (Pubic Hair Especially)

● Behind Your Ears

● To a lesser extent, the rest of your skin

The microbes on your skin can be affected by food, drink, and practically anything that you eat, causing your sweat to either smell differently or be especially rank. Excessive, foul body odor that cannot be easily controlled via traditional methods. I.E., Cleaning, Deodorant, etc., is called bromhidrosis. Bromhidrosis has been proven to worsen when people with this disorder eat, drink, or take certain medicines. For example, the following can cause your B.O. to get worse:

Obviously, whether you eat it via edibles, vape, or smoke it either through a bong or pipe, is ingested. Therefore, it is logical to assume that ingesting cannabis, which affects your body like fish, can also cause your sweat to smell like weed. Additionally, it has been theorized that the terpenes in marijuana also can cause your sweat to smell like marijuana.

FUN FACT-You’ll be a hit with your friends with this bit of knowledge. The apocrine glands, AKA sweat glands, are mostly located in your armpits, groin, and near your breast nipples. These areas produce the most sweat. Therefore, your armpits and genital areas will be the most likely to smell like cannabis.

How to Fix This

The adverse effects of your sweat smelling like weed, at best, can be embarrassing. However, it can also lead to you being fired, or potentially even legal problems.

So, how can you fix this? Well, the good news is that for most people, basic hygiene practices can help you solve this problem along with other measures. This video below gives you some general guidance on dealing with bad body odor.

Below are also some general advice on how you can self-treat rank BO.

Change Your Soap-If applicable, stop using scented soaps as they can worsen the bad smell. Also, you may want to try specialized anti-bacterial soap.

Shave-Body hair is known for trapping in your sweat and bacteria. So, if you are worried about pot smelling sweat, you should be sure to make sure that your armpits are neatly trimmed or shaved and that you trim the hairs in your genital areas.

Take Off Your Clothes-Immediately, remove any sweaty clothes after exercising or hard work.

Shower More– If you have been diagnosed with bromhidrosis (abnormal body order) or are self-conscious, you need to shower at least two times daily.

Extra Strength Deodorant-First ask your local pharmacist if they carry any industrial-strength deodorant and see if that will work. If that doesn’t work, see if your doctor or a dermatologist can get you prescription deodorant.


I hope this article helped you better understand this vital subject of poop and sweat smelling weed. And, hopefully, with this knowledge, you’ll be able to impress your cannabis smoking friends and also be the life of the party at a cocktail party. 🙂

Seriously, though, you likely should not worry if you have any of the above issues. Sweaty smelling feces is caused by digestion that happens when you are eating edibles. Your sweat smelling like cannabis is also simply an issue of your skin microbes interacting with skin microbes that interact with your sweat glands. Most likely, each of the above could be embarrassing, but they are most likely harmless.

If the above causes you to worry, you can either cut down on cannabis edibles and/or take extra preventative measures to reduce or eliminate body odor.

Why Does BO Sometimes Smell Like Weed?

The first time I noticed my BO smelled like weed, I’d just had sex with my girlfriend at the time. She nudged her nose affectionately into my chest. “Hey, you smell like skunk,” she said. I sniffed my underarms—she was right, I did.

Turns out I’m not the only one to have experienced skunky sweat. A Google search revealed several discussions and a Reddit thread where others talked about the phenomenon. Like me, most were baffled. “I smelt my armpit after working out,” Reddit user RIP_MAC_DRE told me. “I had been smoking for maybe two or three years at this point and noticed it smelled like weed; I thought it was pretty funny.”

I stayed up all night trawling the internet for answers. But my search brought up little more than the “top answer” on Yahoo Answers, which was just a description of how to wash. Undeterred, and with nothing better to do, I sought out some of the world’s most eminent biologists and cannabis experts and distracted them from far worthier business in order to discover, once and for all, why my BO sometimes smells like weed.

In an original piece of research for VICE, Dr. Matan Shelomi, a researcher at Germany’s Max Planck Institute for Chemical Ecology, compared studies that broke down cannabis and human sweat into individual chemicals to see if there were any shared compounds. Out of 233 elements and compounds found in marijuana and nearly 100 in human sweat, 11 matched.

“It looks like several of the compounds most strongly associated with the distinct aroma of Mary Jane are also found in gym socks,” Shelomi told me. “Now all we need are a statistically significant number of sensimilla-scented volunteers and an olfactometry lab that’s totally down for whatever.”

Scientific breakthroughs started coming thick and fast. It wasn’t long before Dr. Shelomi realized the cannabis smell probably comes from apocrine sweat as opposed to eccrine sweat. Eccrine sweat is clear and watery, and used to cool the body down, while apocrine sweat glands, clumped mainly around the armpits and genitals, activate during sex and times of stress.

“I remember walking into a [high school] class before giving a presentation and noticing it,” Trent, from Kansas, told me. “Eventually, I figured out that my armpit sweat only smells like weed during or before a stressful situation.”

Dr. Shelomi used this as the basis for a potential hypothesis. “If [this] experience holds true for others, then we can narrow down the source of the pot odor to apocrine secretions.”

Another hypothesis, suggested by Dr. Justin Fischedick, a researcher at the Institute of Biological Chemistry at Washington State University, is that aromatic plant chemicals known as terpenoids and terpenes (“terps,” for short) are present in the sweat. Plants release terps from their leaves and flowers in order to attract pollinators and repel munching insects. “It seems like people who work out are noticing it quite a bit,” Dr. Fischedick told me. “Since [terps] are fat soluble compounds like THC they might be stored in fat cells and get excreted during exercise.”

That covers people who still consume cannabis, but I haven’t smoked any weed in years. Perhaps it’s because, when I was young, I got through enough of it on a daily basis to permanently alter my body odor. “It wouldn’t surprise me if heavy weed intake could alter your smell,” Dr. Shelomi told me. “Others online also report having stopped smoking but still reeking of it.”

I didn’t want to second-guess an expert, but this just seemed impossible to me. The smell, I figured, is more likely caused by dietary plants that share the same terps as cannabis—an idea mooted in the Reddit discussion. “There can be some similarities between the smells,” wrote user LarsHoneytoast. “I think weed, BO, and the lettuce at Subway are all in the same realm of scents.”

I needed to confirm this hypothesis, ideally with the help of someone who isn’t named after a breakfast dish. “The smell of cannabis is produced by its terpenes,” Dr. Franjo Grotenhermen, the executive director of the International Association for Cannabinoid Medicines, told me. “The consumption of other plants with the same terpenes may result in a similar smell.”

Thanks to weed enthusiasts constantly breeding new strains, there are now a host of cannabis varieties that share terps with many other plants; famous strains like Blueberry Cheesecake and Orange Bud are two notable examples. So there are plenty of plants out there that could make sweat smell like skunk.

But if cannabis-smelling terps are so common, why don’t more people smell like London’s Hyde Park on 4/20? Well, BO is not just caused by terps, but also by skin-dwelling bacteria that break down sweat molecules into smaller, volatile compounds that evaporate into smells. Apocrine sweat is also a cocktail of minerals, pheromones, and urea. It seems the skunky smell is down to a particular combination of these composites, making it unusual but not outlandish.

There could be many more people out there who have the right combination of factors to produce the chronic whiff, even if they don’t smoke weed. Naturally, they wouldn’t notice because they’ve never smoked marijuana and so wouldn’t know what to sniff for. Or maybe they know what it smells like but just don’t care enough to spend all night on Google, before bothering multiple scientists about it.

All that can be done for now is to trot out the old scientific banality that “more research needs to be done.” But at least Dr. Fischedick is up for it. “The only way to find out for sure would be to ask volunteers to smoke a bunch of dank, work out, collect some sweat, and measure it in machines,” he told me.
