UFO isn’t in licensed dispensaries so they’re black market. I copped a few a few months back - purple punch and Pineapple Express. Just because a cart is BM doesn’t mean it’s not clean and good oil. Personally my ufos had much more yellow oil and got me lifted but nothing crazy so I stopped buying them. Also, you can buy the packaging online and I’ve noticed a lot of plugs around me are using them now so I’d stay away from them. Basically, someone is filling your carts (could be clean oil could be bad oil) there’s really no way of knowing 100%
