I think the most harm in sugar and cocaine come from their refined and concentrated forms.

I understand people have been chewing the leaves of the Coca plant for millions of years and in that form it's a mild stimulant, akin to coffee consumption. However I have never tried it, nor have I read scientific literature on that, so it could be an 'urban legend'.

I grew up in the midst of the drug culture, back when people snorted cocaine. I never tried it as I realized it would quickly shrink the membranes in my wallet
