These posts were made about smoking to sleep, and it's effect on blood glucose.
Smoking pot has relatively no effect on your blood glucose. Still, it is a potent drug and needs quite a bit of energy to withstand. For instance, someone whose glucose is low and smokes might faint because chemical processes are happening without proper energy to fuel them. Similarly, one who drinks alcohol and smokes may enter a state of black-out. This is because your body quits producing glucose when you drink an ounce of alcohol, for up to an hour. This is why marijuana is "stronger" on an empty stomach.
As for the hunger. It's nothing to do with glucose. It's your hypothalamus (You know, that part of your brain you're screwing with), that is stimulated and causes you to eat more. This is due to the fact that your hypothalamus is deeply related to your food intake. In fact, for decades people have been trying to form an "anti-pot" that causes your hypothalamus to resist hunger. Which is a stupid idea because people will get hypoglycemia from it.
As stated above, as said to me, as written in books, "Moderation is key". But if you are hypoglycemic, and just dead set to smoke, eat first, raise your glucose levels. Afterwards, snack A LITTLE. And if you're an elderly hympoglycemic, don't try this at all. There is no scientific data on this. Just many bad experiences that I've read about during my internet lurkings.
Have fun.
