You can use it. It works very well.
I don´t remember the exact temperature, the volcano classic, I guess, is the analog one (there´s another volcano with a digital panel for temperature).
I think the temperature is lower than for vaping weed.
I´ve use this method and it works, the "vape" is not as bad as smoking a dmt joint.
Look in this forum for older post, go to search and then put volcano in the topic or word field.
