If you’re wondering how to get a dab pen past the metal detector at a concert, you’re in luck. The TSA does not confiscate dab pens during a search at US concerts. It must look like a regular vape pen without any wax residue in order to pass the metal detector. To remove the smell, clean the pen thoroughly before placing it in the metal detector’s bin. Keep in mind that some concert venues have strict policies against vaping, while others are more relaxed.
