I have never smoked pot before, but i wanted to ask a few questions just in case the opportunity rises. I have considered trying marrijuanna medicinally for my bad discs and sciatica i chronically have. At the moment i take 4x 7.5's percs a day along with four 50mg tramadol, but i would like to go with something more natural. Perhaps a less addictive potential. my questions: 1. At this moment, what are the best strands for a mental high, physical high, or both? 2. If i were to smoke two different strains (one with mental, other physical high) could i achieve both highs, or would one cancel out the other? 3. How effect are pot brownies? (bio availability, if that's the correct term. If anyone is to answer this, i would greatly appreciate this.
