I'm going to throw this out there in case anyone is feeling like being helpful. I don't have a lot of experience with mmj, but am trying to learn and use it to help with a couple of conditions I have. What are the advantages of a vape pen? I did a little research and saw there were vaporizes for dry herbs as well, which seems interesting. How do you make sure you've got the right oil, cartridge and battery? Are most of the cartridges and batteries interchangeable? I'm a bit lost, but still trying to figure it out.
