As a lecturer I need to speak many hours a week

In regards to changa, most explorers on Nexus rave of glass vapor genie

Has anyone tried a non-flame portable vaporizer with changa?
Do they work well for changa?

my gratitude for your guidance

Most of the portable vaporizers work with oils, it might be better suited for pure compounds rather than changa if they heat up enough for vaporization.

Very clear, thank you Coja
