does marijuana?

I noticed whenever I consume marijuana I end up having this "panic attack" type of reaction. Well I recently discovered I have hypoglycemia. Turns out these Panic attack meds they have had me on for the past 4 years may have been a misdiagnosis. I only have these hypoglycemic episodes after I consume. So here is my question, Marijuana is proven to absorb carbs during the growing process and end up being a better and stronger plant, can the plant still do the same thing in a chemical reaction once it is inside of the body? Can marijuana consume the carbs in one's body, and could this be the real reason the "munchies" are experienced?
