i smoked weed for the first time yesterday and it took awhile to get high. i honestly don't even know if i was high or not. but towards the end, my left side of my chest towards the middle kinda hurt and felt weird, like a knot. i thought my heart rate was speeding up so i felt my heart and it felt to me WAY WAY TOO and FAST. i made my bf feel and he it was normal? i started flipping out and had a sort of panic attack. was i high for a little bit or what? is this normal to feel that way? does smoking weed always makes your chest hurt and feel like its tightening???
