Does Hemp Oil have THC in it?

I was thinking of taking the plunge and trying Hemp Oil but I have no desire to use drugs. I am getting good results with virgin olive oil but I would consider using Hemp oil if it did not expose me to THC. I am not suggesting that THC is bad but just not for me. I am currently at about day 15 with cold pressed virgin olive oil. My teeth are brighter, my brain fog is diminishing, my eyes are less red, and oil pulling for 20 minutes makes me keep my mouth shut for 20 minutes each day...leading to a prayerful meditation time...that I find a great bonus to oil pulling. I am considering oil pulling with Walnut Oil next but I am keeping a close eye on this Hemp Oil thing... I am in perfect health but maybe Hemp Oil is worth a shot. Could someone tell me what a piss test would reveal if I were to pull Hemp Oil?
