Dab Rigs, also known as "concentrate pipes" or "oil rigs", are one of the best ways to enjoy your legal essential oils in our modern times. Many years ago, when dabbing first started becoming popular, you would just attach a nail onto a huge water pipe and go to town. This resulted in people using large bongs for dabbing, causing a massive drag when taking an inhale, which any dabber knows is not a pleasant experience. Times have changed and so have modern day concentrate rigs, thankfully.
