Yuck Mouth strain guide
Yuck Mouth is an indica-leaning hybrid bred from GMO Cookies and Do-Si-Dos. Despite the name, people know it for a gassy, nutty, slightly funky smell and a calm feel that still leaves room to think.
Where does Yuck Mouth come from?
Two strain databases agree on the parents: GMO Cookies, better known as GMO and famous for its garlicky funk, and Do-Si-Dos, a sweet, earthy strain from the Cookies family. The original breeder isn't named in either listing.
Reviewers mention numbered cuts such as Yuck Mouth #4 and #9 from producers, which suggests several selections are out there. One strain database calls it about 70% indica.
What does Yuck Mouth smell and taste like?
Yuck Mouth smells gassy and earthy, with diesel and wood up front and a nutty, creamy note underneath. One strain database compares the taste to creamy peanut butter with a spicy diesel edge, and some people pick up pine.
We couldn't find published terpene results for Yuck Mouth, so we haven't listed any. Check your product's label if it shows a terpene breakdown.
Yuck Mouth effects: what people report
People most often describe Yuck Mouth as focused, relaxed and happy, with a calm body feel that doesn't flatten their energy at first. Some call it talkative and creative, while others say higher amounts lead to couch-lock and sleepiness.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your tolerance. Dry mouth and headache are the complaints that come up.
How strong is Yuck Mouth?
Yuck Mouth is a high-THC strain. One strain database lists an average of about 24% to 25% THC, and one reviewer on one strain database cites a product near 24.6% THCA. CBD is very low.
Start with a small amount and wait before having more. The numbers on your label matter more than the name, and our THCA vs THC guide explains why the two figures differ.
Buying Yuck Mouth in Canada
Since there are several numbered cuts, check the label for the producer and any phenotype number.
Look at the THC and CBD numbers and the packaging date, since fresher flower keeps more of that gassy smell.
Yuck Mouth vs Do-Si-Dos
Do-Si-Dos is one of Yuck Mouth's parents, a sweet, earthy Cookies-family strain known for a relaxed, heavy feel. Yuck Mouth swaps much of that sweetness for gas and funk from its GMO side and is more often described as focused and talkative before it settles. If you prefer sweet and earthy, choose Do-Si-Dos. If you like savoury, gassy strains, Yuck Mouth is the one.
