Is it posible for a person to be completly intolerant to marijuana?

My business partners and I recently retired from the oh so lucrative marijuana distribution business. As you may have guessed, I at all times had a large supply of very potent weed. In my years of business i would occasionally "smoke" with customers just to prove the quality of my product, but i would never inhale and i NEVER got any high feeling from it while the kids i smoked with out be stoned beyond belief. now that i nolonger deal, im looking to see how the other half lives and spend my money on some good tree, but i've been trying to get high for months, smoking the best stuff possible and I still don't even know how it feels to be high. I get no intoxicating affects at all from smoking, so i ask you...IS IT POSSIBLE FOR A PERSON TO BE COMPLETELY INTOLERANT TO WEED?
