Experiences - is possible to be born with a natural very high tollarance at some substance

[thecandytripper]

hello ok today a swim was at home and he was excited to try morning glory seeds,and a lot of people tell him that if you take to much you can die...so he take 250...after 3 hours he didn't feel nothing, just a little bit lightheaded... so he take 400 seeds more and nothing just after 3 hours and a half he had a stomachache but nothing else...
swim already tried lsd...and he know that he have a good tolerance for hallucinogens...
swim wasn't sure to take other seeds because a guy on youtube put a video and say that he take 800 seeds and he feelt very very bad and he was close to die.

so swim should take more??
is normal what happend to swim??
is possible that swim as a tollerance at this substance from his birth??


(swim last lsd rush 6 month ago...the resistance of swim go down...so...)
swim was pissed off...
