How much more efficient are they than bowls or blunts? I just made one out of a light bulb (non frosted lol) and I just want the statistics to it.

I used to have one. I dont really think that it gets you that much higher. I get just as baked from smoking a bong. On the other hand, green hits from a vaporizer taste really good, and they rock your lungs. After a few hits the vapor starts to taste like burnt popcorn.

All in all, I wouldnt recommend buying it, unless you smoke multiple times a day.

Volcano Vapes are awesome. Not really more efficient but good on the lungs, and an interesting way to smoke.

They technically do work better, as they release the active compounds without combustion, but when you have picked up a habitual smoking habit they just don't hit the spot like a good bong rip.

They're really good if you have to be sneaky about your smoking (IE: you live with your parents and they aren't "hip"), but I like to do both.
