Cannabis Strains With Terrible Aromas

One of the things that makes every cannabis strain unique is its aroma. From sweet berry and fruit to earthy, herbal, and floral, an attractive fragrance is native to most strains.

And then there are those that, whether by accident or breeder’s intention, inherited flavors that truly challenge the palate. With names like “Cat Piss” and “Dog Shit,” it’s clear that no one is in denial of this odiferous reality.

Oddly enough, either by novelty or quality of effects, many of these remain staples in the cannabis community despite their strange, borderline terrible aromas.

Cat Piss

This sativa has a pungent aroma that is reminiscent of ammonia–and thus, cat urine. But there’s a reason Cat Piss keeps getting planted, and it has something to do with the buzzy, stimulating effects considered to be worth the funk, according to many However, if you’re susceptible to paranoia and anxiety like this poor reviewer, maybe avoid this novelty strain altogether:

Sour Cheese

Sour Cheese, UK Cheese, Exodus Cheese…all of these strains refer to a lineage characterized by a sour, savory aroma. Offering mellow euphoria that lifts energy and mood, Sour Cheese is a delightful hybrid strain with a funky flavor that most consumers can look past.

Dog Shit

Speaking of animal waste you’d never expect to find yourself smoking, Dog Shit is yet another strain named for its foul-smelling aroma. A hybrid strain most easily acquired in Oregon, its odor doesn’t always come out smelling like sour, funky “doody pies.”


Based on descriptions from Leafly users, M-39 sounds like Canadian ditchweed grown in a tar pit. And, according to reviews, its aroma is most commonly likened to just that–tar. Some say that its abundance can be attributed to its dull, lackluster aroma that made it easier to smuggle.

Grandpa’s Breath

There’s a slightly musty hint to this strain, but it’s really not as bad as it sounds. Grandpa’s Breath is more aptly named for the Granddaddy Purple genetics used to breed it, but still, expectations set by the name can shape the experience.

It’s clear that there’s a layer of subjectivity when it comes to cannabis flavors–even flavors as unusual and questionable as those explored in this roundup. Although you may never want to try any of these, they do demonstrate the vast aromatic spectrum cannabis has to offer. And that, at the very least, is kind of impressive.
