okay, yea, well my lightbulb vaporizer did hurt my lungs at first, and it did taste weird at first. i'm assuming that was the chemicals. but now i've used it enough that all those bad chemicals are pretty much gone, and now when i use it it's great. i also get a "head high" from it. but not a headache like you say. its more like, if i drop a pencil, it feels like my head is falling with the pencil. it's pretty cool.
