Several years ago, I recall hearing of a case where a man sued the government to
be allowed to smoke {*filter*}. He was seeing halos around lights, he was
diagnosed with glaucoma, and he claimed that the halos went away when he
smoked dope.
The last I heard, he was being supplied with government-grown {*filter*}.
I'm wondering whether this is still the case, and whether {*filter*} or THC
has been studied for use against glaucoma.
