Why Does My Poop Smell Like Weed?

Poop that smells like weed may be related to how certain plant chemicals, like those in cannabis, change the way your gut works.

Explanation

Your gut is home to many tiny bacteria that help break down the food you eat. Sometimes, chemicals from plants, including those in cannabis, can change how these bacteria work. Using cannabis or eating foods that contain similar plant compounds might lead your bacteria to produce different smells. When these chemicals mix during the digestion process, they can sometimes make your poop smell a bit like weed. This does not necessarily mean there is a problem, but it shows that what you eat or use can affect the odor of your poop. Some people notice this smell if they use cannabis regularly because the compounds found in it can change the balance of the bacteria in your gut. Additionally, other vegetables and plant products might also create this effect. If the smell continues or makes you feel uneasy, it might be good to talk with a healthcare provider who can help check your diet and gut health.
