euphoria, huh? well... there are different forms of it.
jillybean, as mentioned already is notorious for being euphoric, but i'm pretty sure THAT strain wouldn't impress me much as it's also knock out stoney from the reports i've read and i despise getting stoned.
at the other end of the spectrum, ORIGINAL kali mist has an intensely blissed out buzz that's similar to a shroom trip... you want REAL euphoria, try shrooms! weed can put an ear to ear laugh your ass off grin on your face, but a good shroom trip makes you feel in harmony with the entire universe. as weed tends to make fun stuff funner, it also makes no so fun stuff seem more annoying to freak out than it should be where as much as i hate getting wet, i was totally happy walking home in the rain after a concert on shrooms. back to KM... i wouldn't call THAT perfect either as it's so racy. you can't sit still on it. it's an awesome & fun buzz, but not if you want to watch a movie or listen to tunes as it makes your mind and body both race... it's too specific. new KM sounds like the buzz is about the same, but the delicious crushed red pepper flavor has been toned down to fruity & spicy now.
8 miles high is MY personal euphoria champ at the moment because it's energy profile is TOTALLY neutral, it doesn't melt you into the furniture like indicas, but doesn't fight you when you want to mellow out either. it was perfectly balanced fun to me. if i were running a marathon, i'd go with kali mist, but for 24/7 whatever smoking, i love 8 miles high. i can't wait until it comes back in '13! i wish i had some right now. my last 4 beans died of mold.
sadly, i've had 2 out of 2 attempts to grow laughing buddha fail too. the 1st one never popped though it was probably cold related as nothing was that time and the second one apparently got caught in it's hole and snapped it's stem trying to grow. i'd expect that to be an fun strain to smoke.
for me, i only get euphoria from sativas and dominants. anything stony only annoys me. just getting high make me happy, i think euphoria is more common to sativas than indicas. it is for me at least.
OH! short stuff's onyx had a really fun euphoric buzz that was different. it was really touchy feely. for some reason, it made me play footsie with myself when i was buzzed and online. it was different from any buzz i'd had before. i'd buy the strain & grow it if it didn't taste actually like diesel fuel which is disgusting & unnatural to me. i'd gladly smoke some right now & just deal with it though as i have nada. as popular as diesel is with others, you might like that one more than me. it would be a favorite buzz if i could just get it in a different flavor.
