My bong recently broke so I bought a vaporizer, but never used one before. I watched several videos and thought I had it down well enough, but when I tried it I went into a coughing fit for about 10 minutes. Hell my chest still hurts and that was a couple hours ago. I'll describe what I did in detail and maybe someone can tell me where it all went so bad. First off it is an E-Z Vape 5 and brand new out of box. I played with the buttons a bit, set it to 200, then 400, then turned it off and read that 360 was the right temp for weed. So I ground up about 3/4 of a gram fairly finely but not like powder. Then I sucked it into the glass tube and it rested against the screen. It was falling out a little so i poked it against the screen. I then turned on the machine and put it at 360. I connected the tube and stared at it for a second. I didn't see anything happening so I gave it a little tug and the glass filled with white smoke. It was really clean tasting and didn't make me cough. I pulled again though and it was very very bad. Coughed like crazy. So I unhooked the tube to see what was going on and there was a big black spot on the herb. I decided to loosen it up and let it sit directly on the ceramic heating element instead of being packed in the back. It made white smoke for a while but eventually stopped at which point I began coughing uncontrollably. I think if not for the albuterol inhaler I found, I may have died. Well probably not, but man I know it isn't suppose to be like that. Help?
