The last couple times I've been high, I have had an insanely fast and strong heartbeat. I'm pretty sure it's not just my imagination, because when my friend checked my pulse on my neck, he also thought that it was quite fast. It feels like my heart is beating at the same speed that it would after running a fast mile or two.
This has only happened with the latest strain of weed I bought (trainwreck), so I believe that to be the cause, as I am in good cardiovascular shape, I do not smoke cigarettes, and I almost never drink.
Is this something to worry about? Have you guys ever experienced anything like this?
