Already vaped bud (AVB) is what is left behind after cannabis has been consumed in a vaporizer. It is basically the weed remnants from your vaporizer following a session. These remnants can certainly be reused in various ways that make total utilization of your buds a possibility. Most times, cannabis that has already been vaped correctly and at the right temperature will look somewhat roasted with a medium brown appearance. A vaped weed should not be too dark. On average some vaped weed might be dark or even lighter, depending on the number of cannabinoids remaining in it. And since there is no specific way to test the content of a vaped weed, what we do is use the color to determine whether it’s good or not.
