panic attacks can take MANY forms... since everyone reacts to things diffrently there is no set values... all a panic attack is (medically speaking) is your adrenaline glands putting out mass amounts of adrenaline, for no reason at all... usually the body pumps out adrenaline when you're gonn ahve to fight or run or life/death situations. but with some peoples minds, especially when smoking, some how the brain gets crossed signals and will produce massive ammounts of adrenaline (i once read the average panic attack produces more adrenaline then you'd find in someone who's being shot at... THAT'S A HUGE FUCKING AMMOUNT...) even if you're calm.. since adrenaline is energy, and you don't actually need to use it, you notice it alot diffrently then you would otherwise... ever notice how you're scared that adrenaline goes to pumping either your legs to run faster, or your fist fly faster? without an outlet the burst of adrenaline has horrible effects...

lightheadness.. even passing out/fainting (kinda feels like you lost ALOT of blood) superly highly increased heart rate... you swear it's goign to beat out fo yoru chest and you'r going to have a heart attack... can cause blindness (not something tha'ts really talked about, but i have personally experienced this, my vision went black for over 10 minutes when it was time for me to go to a denist... i'm more afraid fo the dentist then anyone i've ever known.. i've passed out in the chair twice now, and i've been to them all of 10 times at most...) you can break out in cold sweats.. like you can be cold, but your body starts pumping out sweat, to where by the time it's done it looks like you jumped in a lake... trouble breathing, those are alot of common occurances among panic attacks...

your best chances while smoking to avoid these effects would be going with indica.. more of a slowed down couch lock high... there's no visual way to tell unless you're growing (the two plants vary greatly) but other then that, there's no real way to tell other then trying it.... if it gives you a realy energetic head high, it's sativa, if it gives youa really down, couch lock high, it's indica...
