For me, this is a good strain at bedtime. It is easy for me to get a bit too much but any I get does a good job with the pain. I think my wife likes me in a Blue Dream. Grin.
This strain is right there with Grape God. I have pain, I don't need to feel f*cked up, I need relief. The first time I tried Purple Arrow I had nerve pains shooting down my neck into my upper back. After the first drag the pain was gone, and I could still function at about 90%. Everything else I've tried hits so fricking hard I can't even think. With G.G. or P.A. I can spend time enjoying the smoking aspect of medicating and still make it back into the house to help out in the kitchen. I gave the strength rating of 9 because it kicked the shit out of my pain, not by how buzzed I got.
My favorite strain to date! I get a very nice high and have my pain properly relieved, while still being able to function well. I see comments about having a good high after about two or three bowls and I can't figure out how anyone gets past the third toke, (soft chuckling in the background, hmm).
If I ever grow any mmj for myself it will be this one.
