Many of the same arguments apply to alcohol, and indeed overuse of alcohol
is a bad thing, but moderate use is a good thing and a blessing of Hashem.
I don't see why the same should not apply to marijuana, at least in theory.
To my mind the only reason not to use it today is that the mere act of
buying it requires getting involved with undesirable people, and all the
bad things that can come from that.

The only source I can think of about drugs is the gemara in Arvei Psachim
that *advises* against get addicted to anything, lest one find oneself
one day without the means to satisfy the addiction, and be forced to
resort to stealing.
