There's some quality Lucy coming from California to Kansas City, and one hit gets you going real good. Of course, it's not the shit they made in the abandoned missile silo in Wamego, Kansas [some of which is still floating around, but it's getting harder and harder to find], but it sure is some very very very decent shit, barely able to differentiate between the two while I am trippin'. I tripped for 17 fucking hours, 17 HOURS, off of one hit. I had already peaked and dropped down into the more 'chill' part of my trip, but I smoked some weed and it seriously brought the fuckin' 'cid back in full force, harder than before. It was like I was peakin' off 2 hits, when I had only taken one. Anyways, it's out there, and when someone sells you some bunk shit, bust 'em in the mouth and tell people 'so and so' has bunk shit, so that they don't waste their money. Then, seriously, wait another week to try a different kind of lucy, because if their shit was legit but weak it could have been enough to build up your tolerance and make you not trip off of some true quality.
But anyways, there are a lot of other factors, such as handling of the tabs, to your mindset coming into the trip, to whether you were hungry, thirsty, malnourished, too full... that could fuck up the amount you trip. But who knows I wasn't there...
