Cannabis oil changes over time, most notably in its flavor and color. As you use your vape, minor oxidation will occur as air is drawn through the oil while the cartridge is activated. This is an entirely natural bioactive process that occurs over time due to small amounts of oxygen interacting with the oil through the ceramic core of the vape cartridge. If the cartridge is stored on its side or upside down, some of this darkened oil will recombine with the rest of the oil, taking on a darker homogenized amber color and not affecting taste.
