i think u just think too much. let go your thoughts and relax. I know people that r scared of pot and get paranoid with just the smell. Just coz they tried to see smoking as a "trip", to see the effects. They were probably a little bit worried about weed in their minds, just like most of first timers i think, and they made it "big" in their heads so they freaked out.

just chill, probably the weed was bomb and u got paranoid.
