I haven't finished any of my cookie wrecks yet, but I have tried it from a dispensary that used to grow it out in CO. I think there were different phenos in one jar or grow conditions caused a couple diff flavors. From my experience with it there were two distinct flavors and smells, one was almost all gsc (gassy and slightly cherry fruit) smell and flavor, while the other variation had that same smell but with the addition distinct spicy undertones especially on the exhale. It was smooth and I did not cough when I smoked it through a clean percolated beaker bottom bong. The flavor came through strong and the effect for me was probably about 70% in the body and 30% in the head but that is from my impression from using it not a fact. Effect lasted long, maybe 2-3 hours if you don't keep smoking but I would rip a bong every couple or few hours once you feel the way you want. Lots of possible medical benefits too. I would use this for afternoons if I want to relax and would also use this to stop anxiety and depression as the balance between head and body was ideal for me. It relaxes the body and mind and also somehow stimulates the mind, but in positive ways. The effect also seems ideal for migraines, appetite issues and nausea, and mild to medium pain. Hope that helps. I think those I had in ounce were both cookie dom but one almost pure and one with a little trainwreck, I have seen a pheno online and heard of one from a buddy that lean mostly trainwreck and have a mostly citrus thing going on. Wish the dispensary still grew that strain and a few others they dropped. They switched from soil and coco to all coco and now nothing tastes or smells good. It's unfortunate because they were my favorite dispensary and were close to home. I hope you enjoy your cookie wreck, cant wait to hear the flavor and smell your end up with.
