i think i’m broken??

i recently took 620mg for my first time ever and i hardly felt ANYTHING, it felt like a very mild buzz. i was waiting and waiting for an actual effect and it just never hit. science?? explanation?? i am actually so beyond stumped. for my first time doing it i thought i’d be on mars at that dose. why do i already have a tolerance if i’ve never done it before? i don’t wanna be built different i just want my high lmao
