Infused joints are a novelity and a waste of product. Flower burns best between 325 to 400 degrees where as concentrates burns best at 500-710 degrees, it is why we get the nail heads so hot and higher if you are doing insane 1 gram hits. And Kief burns best at 170 degrees to 190 degrees. So infused joints are a waist of money and product. Yes I have had them and moonrocks too, but that being said it is a waist of money and not something I do anymore myself.
It's definitely a waste, but I would prefer a moonrock join over a regular. My issue is when people try to coat the outside and it drips all over the place.
