Tinctures (Oils) Prepared in either alcohol or organic oils such as coconut or olive oil. Ingesting a tincture or drops of oil infused with medical cannabis is a very easy method of dosing the medicine. It has little cannabis odor, is easily transportable, is very discreet, and allows the patient to carefully control their dosage. Start with a small amount and gradually increase the dosage until you are comfortable with the relief you are experiencing. The effects take only a short while to present (15-20 minutes or longer depending on your metabolism) and have a subtle, long lasting effect that leaves the patient feeling body relief with a clear mental calmness.
