I have found that less is better too much especially if I smoke it will result in me being too "clouded" to get things down also I end up having a "couch-lock" thing. Im thinking this is from mainly indicas. I have read and heard sativas may be better and I think that I may have had some good success with sativas. My friend has some medical strains he is willing to let me try. He has some purple urkle, blueburry kush, sour diesel, and snow cap. I know what the markings on the bags say...but the information I find on the internet points some of the strains that were marked sativa as indica or even a hybrid. For example the bag of sour diesel he has says it is a sativa. On the internet it says that strain is either a hybrid or a indica. (depending on site) Also what strains have you guys found most effective.... and what delivery method.
