This video is somewhat biased, it's mostly correct but not totally, I'd be interested to find out where they acquired their "statistics".
Now as it happens, despite my personal issues with cannabis, I am pro legalisation. The problem is when it's taken daily as I have done for so long.
Hemp is not illegal over here, but it is not used anywhere near enough, the price of hemp seeds (for consumption) is astronomical, about 5 times as much as hemp supplied as fishing bait. I guess that point highlights one of the gross contradictions in our society, we are told to eat healthily, however this is expensive, it's much cheaper to eat crap. I wonder why there is such a problem with obesity in this nation...
