My CBD Oil changed color, is that normal?

CBD Oil changes color over time due to the oxidation process. Also, over time, high purity (90%) CBD oil may begin to crystallize in our disposable vape pens or cartridges and once the oil is heated via vape battery, the crystals will melt.

Oxidation and crystallization are entirely normal and natural, and they do not affect the composition or the potency of the oil.
