strain with least paranoia?

Hi, im new on the forum but i hada question i thought you guys would be able to answer. I enjoy smoking weed, i do it every so often, but usualy when i get really high, which for me doesnt take a lot cause i have a low tolerance, the high creeps on and i feel a lot of overwhelming paranoia. It happens for the first like 45 minutes of the high, and is really uncomfortable, but then tends to go away after that making for agreat experience. I dont know if its just me..But i was wondering if there were certain strains that were known to have less or no paranoia, and maybe reasons as to why it happens? thanks!
