Skunk 1 for me
It’s tied between 2 for me.
Choco - Latte. It was pretty narcotic to begin with but one time I overindulged and was just about tripping for an hour or so. At some point it shifted from that to what I can only describe as an opiate high.
Kush 4 - Just wow levels of relaxation.
Emerald Jack by Emerald Triangle seeds.
(Jack Herer female x Emerald OG Kush male.)
Bodhi’s Goji OG and also Kindness (Afwreck x Snow Lotus).
Laughing Buddha (Thai x Jamaican) by Barney’s Farm.
LSD of Barney’s
Synergy - Pinequeen x Snow Lotus (just one pheno)
More recently, Ecto Cooler, Marshmallow OG and Ice Cream Cake.
Jack Herer. That bolt of euphoric light hitting me right between my eyes.
The most “clean” euphoric chemovars for me is:
- California Orange
- Cheese
- Blueberry
These old school cultivars pretty much only have euphoria for me which makes me enjoy the euphoric high the most. Other cultivars might have more euphoria, but those have a more muddy euphoria because they might also give a cerebral, relaxing or racy high. For me, these type of highs mess a lot with how I perceive and enjoy the euphoria.

Yeah I had some jack a long long time ago that came out golden colored that was really euphoric.
Would also say Malawi. I had some Malawi in Oregon a couple years back that just had me in the best mood the whole time I was there. Absolutely fantastic. Almost dreamy but functional, saturated, just loving life.
You’d like Blue Cheese (Cheese x BB) and Blue Mystic (BB x Skunk). Great hybrid effects in both. Blue Cheese has a stronger body high. Blue Mystic is a bit more mentally stimulating.
Also Big Blue (BB x NL5) and Northern Lights Blue.
@Prince reminded me of JOTI Pineapple Punch. A bit too racy and in-my-head, but strong euphoria. Elated feeling.
JOTI’s Chemo and God Bud.
Yeah, I know! I was thinking of adding Blue Cheese to the list but I thought to myself that I already had the parents there so 
I believe that most Blue cheese was made with the indica side of Blueberry which drives the stony side of the cross. I might have to try Blue Mystic some day, sounds like it’s a treat. Thanks for the suggestions, they are all added to my future list(aka lonely’s list of possible breeding partners).

I 
this Iranian line I’ve been working with for a few years now- not the most potent or frosty, but the effects can be very euphoric. Like being enveloped in a hot bath… Or maybe like if your body had warm oil running through it like those electric radiators. Great winter strain.
One from last year:
Urkle/GDP, Blueberry
Pretty one with nice effect @SF0, how does that taste? Potency is not everything, when the high is there, you don’t care 
I had some Jack that I smoked just three hits of after a tolerance break. It guided me through almost every high I’ve ever had over the course of three hours.
Anything with Mullumbimby Madness, and some Thai strains, the best strain, I ran, was a freebie from SeedHeaven, by Bob Green, called SFV78
Every plant was a joy to grow and when sharing her at parties, she was a rock star of good vibes!
Some were cut around 16-18 weeks, a few went 20 weeks, and 1 to 24 weeks, so not really for many growers, as most want short flowering times, 8 to 10 weeks.
Hope you find your plant!!
Really, like Skunkman Sam’s Skunk #1?
definitely for the thai strains when talking about psychedelic/euphoric effects. Though jamaicain or zamal strains are quite good at it also
For sure, it is one of my favorites- probably a desert island type thing- maybe not my first choice overall, but within the top 3. The smells and flavors range, some being very, very meaty, some being skunky, some being a weird hospital and days-old fishstick thing. That one in the picture was the meat- smelled and tasted like a very greasy pepperoni, with undernotes of earthy potatoes. Absolutely zero sweet or fruit.
