Your question about nature giving animals a way to get high, yes I've thought that with the parrots... but considering I don't know their fate (not seeing them since), I would have to say that that tells me it's not really the best thing one could do for themselves, or perhaps we should refrain and only partake occasionally... I don't know about using it as an argument for legalization though.
If you really wanted to go crazy with the concept you could look at the snake that tempted man to eat fruit from the tree they knew they shouldn't touch...
