I've recently started using CBD oil and want to make sure I'm taking it correctly. What are the different ways to take CBD oil, and which method is the most effective?

For cancer, CBD should be taken internally through sublingual or oral dosing, for best results.
I recommend starting with tinctures, which are lower potency and easier to exactly dose, and some cancer patients switch to concentrated FECO once they have built up to using cancer-intensive amounts.
