CBD comes in several forms and there are several ways to take it. This list is just going to grow as CBD becomes more widely used.
The Quick Answer:
CBD comes in oil concentrates & tinctures (taken sublingually on their own or ingested when mixed with food), edibles (ingested), powder (mixed with any beverage), capsules (taken just like a vitamin), wax dabs or e-liquid (to use in a vaporizer and inhaled), sprays (usually mixed with a flavour to double as a breath freshener and sprayed directly into your mouth) and topical (mixed with a cream/moisturizer for topical application).
