I've been smoking the strain for pretty good while its only one that doesn't give me a headache so far which is great because all the others that I've tried have. Does anyone know why the some will give you headaches? And are there certain ones that are known for giving headaches? Overall I don't really feel like it helps my pain and probably distracts me a little. I'm pretty sure that it has not helped me with focusing because I have an issues with that but I also think I have other stuff going on. But I like the strain it doesn't choke me i'm not constantly coughing which could be a factor in the headaches also. Now that I think of it I always coughed with the others ! That's very interesting!
