Yeah, unscrew it and if your weeds turned a brownish color it's vaped. Be sure to take a paperclip or something to stir it up after about 4 or 5 hits to get the weed on the bottom.
I swear by the genie dude. I picked mine up at the head shop in my town last week. You have the cleanest head high. This burnt popcorn smell is very true. You CAN virtually smoke it anywhere. I did it in my room right next to my window, and then said goodnight to my parents right outside the door. It might be one of the best inventions for marijuana use if you are trying to be secretive... which most of us are. So go get one.
I'd rather get the Volcano vap personally... Every time I see vaps like those in HT I always think "bullshit".
I was watching this show last week called manswers and they were talking about the different ways you can smoke and that vaporizer pipes get the most thc content from the herb. like 96% pure thc. I tried this crazy lookin thing from a website I found on google called vapor nation. OMG!!! You gotta try it to really know how insanely high you will get using one of these kinds of pipes. nuff said...
