Do you have sources for this? My impression is that cocaine is significantly more addictive than caffeine, which seems like a very large negative. This page (which I believe is meant to be sympathetic to legalization) seems to imply cocaine is 'worse' on every metric: http://drugwarfacts.org/cms/?q=node/28
"My impression is that cocaine is significantly more addictive than caffeine, which seems like a very large negative."
It's not, the addictive potential is almost identical to that of caffeine. The page you're linking to is wrong, they're comparing people snorting (or smoking) cocaine with people drinking caffeine. They're also not comparing the harms caused by the drugs, but rather the harms caused to users. This might sound pedantic, but it's actually really important because the most hardcore drug addicts are drawn to the drugs that have the reputations of being the most hardcore. Which means that cocaine users on average have more health problems that caffeine users, but that doesn't mean that cocaine is any more dangerous.
FWIW the analysis that I'm criticizing as propaganda is straight out of Nutt's research. (Or else is very similar to Nutt's research, I didn't look at the source.)
