UK Cheese , as it’s also known, is perhaps the most famous marijuana strain to emerge from the British Isles. English farmers created this strain by inbreeding Skunk #1, a sativa-dominant hybrid. UK Cheese itself is indica-dominant, with a sativa/indica ratio of 20:80, but the effects are balanced, delivering both a head and body high. It’s a potent strain, with THC levels topping out at about 20%, and it’s known to hit fast and hard. The effects are intensely euphoric, with an upbeat, happy mood, some laziness, and a dose of creativity. Best used to treat pain and stress, UK Cheese is also an effective way to alleviate insomnia and depression. CBD levels are low, less than 1%, so this isn’t a good choice for patients with seizures or other disorders that respond to CBD.
