I've only experienced paranoia once and it was from an indica strain, I had just been on a break from weed for about a week and I was at my buddy's house and we smoked a few grav bongs. I started 2 freak out cause I had 4 little plants growin in my room and if my parents found them they would flip ( the only reason i even had them there was because they germinated quicker than I expected and it was still too cold to put them outside) As soon as I got home I moved them outside and i have never had paranoia again.
