Shoot! I must have cut and pasted this first one, no URL- so try googling the title " Non-psychoactive Cannabinoid Reduces Incidence of Diabetes, Study says"

This one on diabetic retinopathy, I have the URL for-- http://www.mcg.edu/news/2006NewsRel/Liou022706.html

My advice- keep on toking! Diabetic retinopathy is a leading cause of blindness. Cannabis also helps with diabetic neuropathy pain. I tested my blood sugar before and right after toking, only dropped 8 points. Of course your results may differ.
