I'm well acquainted with the spoof aka doob tube. I'm not worried about the smell, just curious about the benefits of a vaporizer. I didn't see this mentioned on the vape construction tutorial, but don't you need to also scrape something out of the inside of the lightbulb to make it safe for use? That's something I'm worried about too. I preach dangers of aluminum to friends, so why corrupt my lungs with something else? I need to do more research.
