Currently I am puffing on some Kosher Kush that is quite euphoric, I have had a couple long term heavy smokers tell me it is the best shit they ever toked. I think this stuff should be pretty easy to find in American dispensaries and I would highly recommend it. Obviously, there is variation in phenotypes to some degree, and some growers will fuck up weed regardless of its genetic potential, but Kosher Kush gets very consistent rave reviews on leafly. I would give it a go if you can.
I should mention that Kosher is pretty indica dominant. A few hits can have you nice and functional with a head high, but if you like to have a heavy session, you will probably be quite sedated. If you like a bit more of a functional high you can't go wrong with some Super Silver Haze.
