When it comes to vaping cannabis, it can be difficult to know when it's time to discard the oil from an empty cartridge. Most disposable cannabis vaping cartridges have glass walls, making it easy to visually verify the level of cannabis distillate left in the cart. As soon as the indicator light at the top of the cartridge comes on, you can be sure that there is much less vapor left inside and you won't be able to inhale smoke soon. The moment the small circular holes in the lower part of the inner steel “straw” are exposed to the open air, you must stop vaping your cartridge.
Depending on the viscosity of the chosen item and other characteristics, a battery may not be powerful enough to work with all cartridges. If the battery is charged and the cartridge is not clogged, you may be forced to admit that the cart is empty if it still doesn't produce steam. Hitting a vaping cartridge even if it is empty can overheat waste oils to the point where they burn, not vaporize. Applying heat is often the best method for removing blockages in cannabis vaping cartridges.
The exact number of shocks produced by the cartridge depends on the magnitude of the shocks and the battery voltage. If you notice that your vaporizer isn't producing enough steam, the airway in the cartridge may be clogged with oil residue. There are some surefire signs that a vape cartridge is legitimately empty, not just clogged or in need of a new battery. When the oil in the vaporizer cartridge is running low, it can be difficult to know if you should replace or refill it.
