It depends on your equipment. You absolutely cannot use a dab nail for smoking dry herbs, but most dab rigs are set up where the dab nail can be removed. If you have a bong bowl that can fit into your dab rig, then it can operate as a small bong! Many prefer larger bongs to help aid in cooling and filtering smoke, but there is nothing wrong with using a bong bowl in a dab rig (just as long as it properly fits).
