Is it normal i blacked out after smoking
So last night I blazed a bong bowl with my bro and our friend and also did a little bump of some coke. about twenty minutes later i was sitting on my friends bed and my head started feeling weird, like my brain was turning around or something weird like that, my whole head started to feel a bit weird then i stood up and my eyes felt a bit weird then my vision started to black out and i fainted, i guess i was down for like 8-9 seconds and twitched a few times. i eventually came to with no memory of going down or how long it was. my heart was racing a bit and i was short of breath, my head still felt a little weird in the back afterwords and my neck is still a bit stiff. what the f*ck was going on? i just dont want a brain tumor or aneurysm or something ha
