I haven't got a clear answer on this and have been wondering for awhile now. What is the highest percent of THC in a marijuana bud? I have a friend who says it is impossible to have any higher than 5% thc and I've read somewhere they say it can have up to 30% THC. What is the real answer? If some strains had 30% THC, would those buds look as if they are like half THC crystals and half leaf/ hair material? Also what percentage of THC would hash have? and hash oil?
