You said that you smoked half of an eighth in one sitting? And it was only your 5th time smoking?

That did it.

Just remember to enjoy everything in moderation. Smoke a bowl, see how you feel, if you feel stoned enough put the bag and the pipe down and eat some fritos and watch a movie. There's no need to use that much bud, you'll get waaaay too fucked up too fast and end up scaring yourself, like you did this time.
