Weed + Diabetes

My boyfriend recently started asking me if I'd be willing to try getting high with him... I want to say yes and try it (I've never tried it before..) but I'm type 1 diabetic and not sure if it'll mess something up for me... I feel safe with him and I love him to pieces but I don't know if it'll end up doing something unwanted to my body... Any ideas or tips as to what I should do...?
