Distill the purified cannabis oil by separating and concentrating the cannabinoids from the other compounds. You can use short-path distillation, which is a technique that uses heat, steam, and vacuum pressure to vaporize and condense the cannabinoids into a liquid. You will need to adjust the temperature and vacuum settings according to the boiling points of different cannabinoids. For example, THC boils at around 157°C (315°F), while CBD boils at around 180°C (356°F).
