When your throat burns after hitting your weed, the culprit is the temperature of the smoke. You can’t freeze your water pipe with water, the glass will crack. Glycerin on the other hand, works beautifully. When you hit our glycerin water pipes, fresh from the freezer, you’ll have much cooler, smoother hits. Dab on down™ to Happy Habits® and treat yourself to a better experience; you’re worth it.
