what's in a marijuana pen?
Some are made to be used with cannabis flowers, some with hash or wax, and some are made to be used with oil cartridges. The vape pens used with dried marijuana flowers and concentrates like hash require a person to load the cannabis product into the corresponding vape pen chamber. This means that the person using the pen knows exactly what it being loaded into it. The vape pens designed to be used with oil cartridges are a little bit trickier because the cartridges are most often purchased pre-filled with the marijuana concentrate liquid.
