Although it is theoretically possible to use a normal lighter to attempt to heat the Nail or Banger of a DAB rig, this is not recommended as it may not be effective and is a safety hazard.
The correct approach is to use a specialized torch to ensure that the proper temperature is reached and to avoid potential hazards.
Therefore, the abbreviation "can heat up a dab rig with a lighter" is not recommended to indicate such an unrecommended heating method.
