if you honestly cannot comprehend why people might legitimately consider the use of cannabis to be a social ill (for reasons other than “they only think people should pray all the time”), you might want to stop using it for a while and reevaluate some things

OK, I'll bite.

It doesn't correlate with violent behaviors, unlike meth and alcohol. It isn't highly addictive like opioids. Users don't tend to spend their lives sedated beyond cognition, like residents of opium dens and absinthe parlors (without discussing what part of absinthe encouraged it).

I don't personally enjoy it, but ... did banning it include some reasoning beyond "Drugs are immoral!"?

You implied that I am regular user, which I am not.
