What you had was a panic attack. You probably smoked some good sativa and you just weren't used to its effects, which differ from the Indica you most likely have been getting(at least I mostly get indica here). Then because you were high you started to focus more on your heart beating which made it beat faster. I am no doctor but I've seen it happen way to often when someone smokes a really good sativa for their first time.

Hey guys, long time reader first time poster :) I was just wanting to get some peoples opinions on this experience i had a few days ago where i flipped out after just one cone. I have been smoking weed for about 2 years now and have had WAY more than one cone at a time before without any problems at all. After about 5 mins from hitting a cone from a plastic bong my heart started beating really fast (i counted 140-150 bmp) so i went and lay down and tried to relax but it just got worse Rating: 5
