I am growing Harle-Tsu from Southern Humboldt right now which is one of the higher CBD strains coming in around 20:1 ratio of CBD to THC.
When I was in Colorado last year I picked up a CBD strain. It was simply named CBD 3:1. I paid $25 a gram for 3 grams because I had never had the pleasure of smoking any before. From the aroma and taste, there was absolutely no difference and I couldn't have discerned the difference in it from any other strain I had purchased had it not been written on the baggy.
When I smoked it first thing in the morning there was a very slight psychoactive high to it but it only lasted about 10 - 15 minutes. At that point, there was a warm sensation in my muscles and especially legs and back. It was like getting into a hot tub or sauna, the muscle relaxation and the other effect was it was almost like a Xanax. There was zero anxiety with it and I was very relaxed mentally and physically. I fell so much in love with that weed that when I got back home the first thing I did was start hitting up a friend in Cali to get some of the Harle-Tsu for me. This medicine is a God send for people with skeletal and muscular problems, anxiety issues, and from my understanding it works well for seizures and epilepsy but I cannot confirm that. I am asking around my circle here though to see if anyone has friends or family with seizure problems that would be willing to try it.
One last thing, it will kill a psychoactive high almost immediately. I noticed that if I was smoking some of my sativa while I was out there and decided to smoke some of the 3:1, it would bring me down almost immediately, like within 2 to 3 minutes tops. Like an anchor. One minute you are stoned as a gourd, the next minute you feel a bit dazed but that was about it.
I hope that helps with your journey.
