You could but I wouldn't recommend it in your new herbalAire. It could get a little messy and the taste would be pretty bad. I wouldn't used finely ground weed in it either, at least not without an additional screen in the bottom of the crucible and another near the top. You don't want little particles getting below the heat chamber or up into the screen on the main mouthpiece and even into your bag. This vape will do great with small pieces and that's what I'd use if possible. The herbalAire is a fine piece of equipment and should last for many, many years....if you take care of it.

If you want to vape roaches I suggest a cheap glass vape like the Vapolution Pocket Vaporizer or the Ubie. Even better use a pipe and smoke 'em.
