I some misconceptions until recently, when experience showed me different, about dry weed not needing rehydration. I thought the only difference between dry weed and rehydrated was how long it took to smoke the bowl--not in the amount of buzz you get from that bowl. But after actually trying the same weed that i had smoked before that was way too dry rehydrated i could definately tell a big difference not just in the burn time but in the amount of buzz from a bowl. If you want the most buzz for your buck, then definately throw in a piece of lettuce into that dry weed! I think it's because with dry weed more THC is burned up than is converted to smoke. That's my theory anyway...i could be wrong.
