Good question...
After having had the luxury (it's not a poor man's game in pa) of indulging myself in mmj offerings in pa over the past year and a half, I found myself needing to purchase one of the more or less disposable cart pens that pa is hot to sell you. I went with a .5g cart of liquid live resin (chaos kush - whatever that happens to be - not lots of info on it but at least I know that in pa they're careful about what they do and don't allow in carts) that screws into a moxie rechargeable cart pen device. I've known about these things of course but was never interested given such a wide open world of wonderful flower to learn about. But necessity called and I'm glad it did. So easy, so potent. I've been live resin liquified for several days now and will keep going until the .5g cart kicks so I can see how long they last. And this after just purchasing what I consider to be a good portable dab device. The world is very very different in pa than it was a few years ago. And to think that in ga, where I was for several days this past week, I was using the cart pen illegally. What a strange world.
