i think it does all just depend on how much thc you get really, cause i think that being paranoid all depends on your mindset before smoking, then you are always a little paranoid, but it isnt noticeable due to the overwhelming feelings and sensations you get, but the more you smoke, the more paranoid you get, and the good feelings and such sort of plateau at a certain point, and the body is naturally supposed to be able to deal with high amounts of stress, but when high you cause more stress upon yourself thusly causing paranoia to set in.

i think the most paranoid ive ever been was a few days ago, some friends and i were taking bong rips, and we finished, then 10 minutes later we do some more hits, and before i knew it i was freaking out, though i was calm going into smoking, so i acted calm, but i got lockjaw, and i just sat around for 3 hours not saying anything, then i started to analyze everything and the role they play in the smoking scene and labeled everyone, but i calmed myself because i knew everything was ok, and i was prepared before smoking.
