This makes even less sense to me (as someone who knows only very little about drugs other than trying weed a couple of times), but doesn't cannabis also have medical use, and further have a lower potential for abuse, at least along the addictiveness axis?

There isn't much evidence for medical use of cannabis and what there is is super weak. That's not to say it won't be proven effective in time, just that the research isn't definitive.

I am not super well versed on cannabis abuse/addictiveness research but anecdotally, sure; as far as I know, it's relatively nonaddictive and harm of regular high-dose use is pretty mild.
