My friend is 6'4 around 280 lbs, I gave him 2g for his first trip and he said he'd never do them again

. He said the confusion was too much for him, like he felt obligated to do something but didn't know what. I gave my weed guy 4g who's like 5"11 190 lbs, when I asked if he tripped he just looked at me wide eyed laughed and said yeah... I tripped. I'm 6'1 185lb and 2g gets me goin. Mike, I think you're just some mushroom consuming monster haha
Maybe it has more to do with the individuals psyche then body mass when it comes to getting the effects
