it all started at my friends house this monday. We went to blaze and i wanted to try some of the vaped keif that i had kept because it looked somewhat like hash and looked smoke-able. So we pull out the pisser(gravity bong) and my friend takes a hit as im cutting up this little brick about a half inch by a half inch. Chop it all up and have a bit of difficulty because it was kinda soft and sticky. Pack a little bit of weed in the bowl and then top it with all of this, it was vape poo right so couldn't have been that potent right? (i thought) i brew my toke and rip it and walk over to the window and right beside i magged out. i couldnt make it to the window cus i have so much smoke in me. Any ways i start dying after the toke like coughing like ive never coughed before. I start to calm down and just chill. About 20 mins later we go upstairs think that were going into his hottub so we get all ready. Just about to go in and my chest starts pounding. And i mean pounding, like if you were standing beside me and my shirt was off you could see my chest pounding and might even be able to hear it. So i start to panic a bit because nothing has even happened like this to me before and my chest is almost exploding. I wait a minute and then tell my buddy and he feels my chest and it like holy thats crazy man like he is freaking out too. We then proceed to show his grandma who also think that this it bad and decides to call my mom. Things kept escalading like this, his grandma called my mom and my family came over and then the inevitable my moms says "lets call an ambulance". So we did and i waited about 20 mins when i heard sirens, looked outside and saw them whizzing by. At this point im like fuck the government theyr stupid and my mom calls back and tells them what happened. Apparently they had a "higher risk" situation and were gunna send another one for me. So like 40 mins later they show up with their equipment and get me all hooked up to their machine. My heart rate was at 140 at that point and was defiantly a lot lower then when it had started 40 mins ago. I get all strapped up and put in the ambulance, and were on our way. Paramedic asks some questions and i answer them and he does some work like puts in an iv ect. You guys gotta remember at this point im ripped from the weed and am kinda outta it So we get to the hospital and my heart rate is a little lower at about 110 but still high. get checked out doctor ask me some question and i take a blood/urin test which i know they'd probably test for drugs but didn't care and couldn't do anything about it. Layed there for a long ass time until a doctor came asked me questions and eventually i told them that i had smoked weed and they said this probably is what caused it. my heart rate had fallen to a normal 75ish and i was feeling fine, about 4 houres after it had started. I am 18 years old and have been smoking daily for about 2 years and nothin like this has ever happened. Truly a scary moment for me and i cannot believe that this was caused by smoking a bit of weed. tl;dr i smoked some vaped keif and my chest started pounding, heart rate doubled and could have even tripled. when to the hostpital and they said it was probably cus of the weed.
