Sorry but even if half of that is true it's not close to being the whole story, the Prohibition of cannabis has prevented the vast majority of studies from being performed (and those that are performed are usually biased against cannabis trying to perpetuate the status quo). Until such time as studies are fully allowed without government restrictions, no research can be taken as fact. Studies in other fields frequently contradict each other, and as long as scientists are being prevented from performing all the studies they want, such conclusions are mostly meaningless. Some of what you say may well be true, but until science has had its say we can't really know for sure, and you're an idiot if you think otherwise.
