Alright- first off I hope this is in the right section, sorry if it isn't. Now, I've always heard that there has been no recorded death in all of human history of someone dying directly from cannabis use. But, the other day I was encountered with an unusual situation- someone I know has never tried cannabis because of he has palpitations of the heart. Now, he said he would go into cardiac arrest if he does (due to the increased heart rate after consumption). So my question is, basically, is he right? I'm sure that there has been someone who has had palpitations and used cannabis before. Any thoughts?
