Not a vape user but I'm going to be. Was in Colorado a few weeks ago and a friend of a friend had a vape pen and I loved it. He was using a wax type product out of a small tin. Looked something like a dip can but smaller. He said this was easier on the pen than ground herb. I've searched like crazy but don't see anything on the forum that describes anything like it. Any ideas what it could be and how do I make it? Besides ground weed, what is the best product to use in a vape pen. By the best I qualify by saying the best high, and the least mess for cleanup? Thanks guys!
