First... I recommend, especially with a condition as serious as Diabetes, that you be honest with your physician. Particularly since THC is present in mentioned medications... it will not be a shock to a doctor that you found Cannabis to relieve symptoms of your ailment.

Also, you should consider the coverage of your health insurance. If you are like the millions of people without health insurance (like me :stoned the cost of those prescriptions, which you will NOT even be taking, will be an added strain on your self-admitted tight budget. Here is some info I found on the cost comparison:
(I can not vouch for its' accuracy... I just shot Google a Q real quick and this is what I got)
How does the cost of marijuana compare to the cost of Marinol?

You won't even need to compare prices... you will have to combine both (unless you got that :greenthumb

But I can't stress enough... Be honest with your doctor. They can NOT treat you effectively if you do not lay it all down. It WILL affect how they design a plan to get you better. As much as I recognize the health benefits and symptom relief of Cannabis it is by NO means a cure to anything that we know of (except maybe a "case of the Mondays" :jointsmile

P.S. If this thread borders the line regarding site rules, I apologize for contributing. I understand that it is frowned upon to respond to threads in violation... but I am not sure about conversations on THC based pharmeceuticals. Just trying to help.
