Immune to drugs? Possible?

Not as general as the title sounds, but i figured itd get more people looking and giving answers. I am not immune to drugs. that would be amazing. I feel however i am immune to the mindfuck aspect of most drugs. The best example i can give is when i did i certain psychadelic that im sure you can easily guess but idk if i can say it on here but whatever. Absolutely no mindfuck. Seeing things yes. But i was myself. Same state of mind. Same when i did dxm. Im a very logicaly thinking person. So im kinda wondering can your brain fight the mindfucking aspect of drugs if it has the ability to still think rationaly? or something like that
