Pounding heart?

I have had some experiances in the past where my heart is beating pretty fast for no reason (when i'm stoned) but a couple days ago it got a little weird. I was smokin chronic with my friends from this bong and after the 5th bowl or so I noticed my chest was hot. I felt it and immidiatly noticed my heart just pounding away, now normally if you try you can hardly feel my heart through my chest. But it was pounding sooo hard that you could see the entire section of skin over my left rib throbbing, it was scary as all hell. I was just sitting there the entire time so I didn't know why it happend. Is this dangerous? I mean, can I have a heart attack from it or anything? Im only 17 so youth is on my side, but it still scares me.

it went away after a while but has anyone else had this happend before?

dude ok i'm not sure but your heart can go really fast but when it stops u sometimes imagine it all happening cos ur high, unlike the poppers i'm sniffing they gave u a real rush of blood to the head and like really fast heart beats

i dontknow man thats never happened to me like that. i mean i had my heart beating fast i just tried to relax and breath in and out slowly

yeah, breathing in and out slowly.

when you get high, you're alot more sensative, and your heart speeds sometimes... also, you might have gotton a panic/anxiety attack sometimes caused by weed in high doses...

jah

chronic...as in coke and weed....or just dank

Because if you're smoking coke...duh.

when i get super paranoid my heart beats pretty damn fast so that could be one of the reasons

I've had really bad panick attacks the only two times I've smoked a huge amount of weed.

out of maybe 500 smoking sessions, ive had 1 panic attack when i was quite new....

you feel like you need to tell your parents to call the cops or something to help you

do you smoke cigarettes??

i do not smoke cigarettes
