I've gotten the feeling like I'm gonna have a heart attack but I dunno if it was a panic attack? I didn't like it though and I also noticed it was just that specific strain of bud I had at the time.

Headin2KONA: very nice information! Thanks a lot. I know that will help a lot of people 'cause it's easy to understand and makes sense (and even so the placebo effect would be enough to cure the attacks ).
