Anyone own this dry herb Vape? I just bought it and have always smoked my herb by combusting it but wanted to try this out for my lungs lol I don't know how long a chamber full should last since it doesn't turn to ash like before. When should I dump it? And I see people save the "used" herb to make edibles? Wow!, this is a whole new world. I got off the cancer sticks and switched to vaping over a year ago and now I'm interested in going from combusting my herb to vaping it. Any thoughts or suggestions would be greatly appreciated!
