Captain Hanks, I got high my first time. I was blazed, no doubt about it.

Anyway, it sounds like you smoked WAY too much man. I have been smoking for almost 2 years now every day (for the most part). I only took 4 hits from a half-ass gravity bong yesterday and was destroyed. I often feel my heart speed up at times and then I start concentrating on my breathing and that always sucks. But just know that your body is self sustaining, it will keep its self alive... so you don't have to worry about it.
