CBD oils (often found in a tincture or a spray) are edible cannabis food items that you consume via your mouth. They are the simplest to administer and do not require any additional tool or equipment. You simply dropper the CBD oil underneath your tongue, wait for about a minute and then swallow. If, however, you would prefer to vape your CBD, you will need to find a CBD oil made specifically for vaping called a CBD vape oil.
