The wifey is interested in getting a vape pen for ingesting Cannabis. I don’t have a clue about what works and what to look for. Can someone point me to an introduction to canna vaping? I did a youtube search and just seem to get ads... I guess my question is mostly about reusability and what I need to get started. I’d like someday to be able to make my own juice but not at first. I won’t really worry about making my own until I get my growing game down and I have a long way to go for that... Can I refill these pens or do I just buy a new cartridge each time. I’m clueless...thanks!
