When tripping on acid, no matter how much I smoked, I don't notice getting high(er). But it was still fun.
Obviously my first couple times i never got high, but, like once after that, i think i got some really really bad weed, and a little bit, (looking back i was obviously ripped off). Nowadays, i al,ways get high. The reason you don't get high the first ocuple times is because you don't know how to inhale. That's why most people rarely not get high, because they take the hit. But i cannot speak for everyone.
