Why Do My Armpits Smell Like Weed? Causes and Solutions

Have you ever noticed that your armpits smell like weed, even if you haven’t smoked or been around marijuana? This strange phenomenon can be alarming and embarrassing, but fear not! There are a few potential explanations for why your armpits may be emitting a cannabis-like scent.

We will explore some of the potential causes of this phenomenon and discuss some steps you can take to solve this embarrassing issue. Whether you’re a casual cannabis user or you’ve never touched a joint, this post is for anyone who has ever wondered why their armpits smell like weed.

Weed And Its Relation To Body Odor

Sweat itself is odorless, but when it comes into contact with the bacteria that live on our skin, it can produce a smell. The composition of this bacteria, known as the microbiome, can be influenced by various factors such as diet and hydration levels.

So, it makes sense that cannabis would affect your body odor!

A study conducted in Germany found that a person’s sweat can be used to detect cannabis use due to the fact that cannabinoids and terpenes, which are found in cannabis, are fat-soluble.

In fact, a study conducted in Germany shows that a person’s sweat can be used to detect cannabis use. This, according to science, is because cannabinoids and terpenes are fat-soluble, which means that before being eliminated through sweat, cannabinoids and terpenes are stored in fat cells.

What Makes My Armpits Smell Like Weed?

It is possible that the smell of weed is coming from your armpits due to the presence of cannabis compounds in your body.

When you consume cannabis, either by smoking it or consuming it in some other form, the compounds from the weed enter your bloodstream and are eventually metabolized by your body.

Another fairly common possibility is that you have been using cannabis-based beauty or body care products. The active ingredient in marijuana, tetrahydrocannabinol (THC), can be absorbed through the skin and be present in sweat. This can also contribute to your skin smelling like marijuana.

These components can be expelled from your body through sweat and even through feces, giving the possibility that your poop may also smell like weed.

A less common possibility is that you are experiencing a condition known as phantosmia, which is the perception of an odor that is not actually present. Phantosmia can be caused by a variety of factors, such as sinus problems, certain medications, and neurological disorders.

How To Prevent Your Armpits From Smelling Like Weed?

First of all, keep in mind that the tips we will give you below can help reduce the smell of weed in your body, but they cannot eliminate it completely.

However, these are the best measures you can take to deal with the fact that your armpits smell like weed:

  • Wash your armpits regularly: This will help to remove any sweat, dirt, and odor-causing bacteria that may be accumulating in your armpits. Use an antibacterial soap or body wash to help kill bacteria and keep your armpits fresh.

  • Use an antiperspirant: Antiperspirants contain ingredients that can help to reduce sweating and prevent odor. Look for one that contains an aluminum-based compound, which can help to reduce sweating and control odor.

  • Change your clothes regularly: If you’ve been sweating or smoking weed, change your clothes to help remove any lingering odors. Consider using a laundry detergent that is designed to eliminate odors, such as one that contains enzymes or activated charcoal.

  • Use deodorant: Deodorants can help to mask odors and keep your armpits smelling fresh. Look for one that contains natural ingredients, such as essential oils or plant extracts, which can help to neutralize odors.

  • Practice good hygiene: Good hygiene practices can help to prevent body odor in general. This includes showering regularly, washing your clothes frequently, and keeping your body clean.

  • Avoid smoking weed: If you’re concerned about the odor of weed on your body, the best way to prevent it is to avoid smoking weed altogether. This may not be an option for everyone, but it is worth considering if you are concerned about the smell.

In case you do not use marijuana in any of its forms, Doctor Armpit indicates that the problem may be due to a bacterial species called “Gram-negative” and suggests to stop using regular deodorant or to try an antiperspirant for a while to imply a sudden change in the microbiome of the armpit.


If your armpits smell like weed, it could be due to a variety of factors, including being in close proximity to someone who has been smoking marijuana, using a skincare or beauty product that contains marijuana-derived ingredients, or naturally producing a weed-like smell.

To prevent or eliminate weed smell, practice good hygiene, eat a healthy diet, wear breathable clothing, and consider using a natural deodorant. If the smell persists, consult a healthcare professional to rule out any underlying medical conditions.
