I smoked pot every waking hour for three decades, so I know a little bit about it. 
One thing a lot of people don’t realize is that there are a lot of different cannabinoids in pot, and depending on the strain, the growing conditions, the curing, etc., they can be present in different proportions. This makes all the difference in how the pot makes you feel. Some pot makes you sleepy, some makes you energetic, some makes you goofy, and some makes you so stoned you can’t think straight, just as Argent Towers was mentioning. It is one of the cool things about it, really. So not only do people react differently to pot, different kinds of pot affect you differently.
Yes, some pot makes me paranoid, but I can usually dismiss it, because I know intellectually that it is the pot that is doing it to me. As far as munchies go, I have found that eating is a good cure. No, I would not commit a crime to satisfy hunger. As far as dismissing the effects, caffeine seems to counteract it pretty well. I make it a point not to drink caffeine when was getting high, because it is a waste of two substances that cost money. Beer on the other hand…
