Sublingual administration promotes absorption through the mucous membranes under the tongue. This occurs when the CBD oil is placed under the tongue and allowed to dissolve. Through sublingual administration the entrance of CBD into the bloodstream is quicker due to bypassing the digestive system where they have to be broken down and metabolised. With the growth and popularity of CBD products, the sublingual method of administration has become the most common and used way of taking CBD.
Key factors of ingesting CBD

- Bioavailability: Low (20-35% of CBD consumed)
- Dose accuracy: Very high
- Time to onset: 40-50 minutes
- Duration of effect: 4-6 hours
The sublingual gland, found under the tongue, is able to absorb any substance that is administered. This allows it to go straight into the bloodstream, avoiding the liver where substances are normally metabolised. This is referred to as sublingual consumption or administration. Typical products which can be administered sublingually are CBD tinctures, lozenges and sprays. As sublingual consumption allows the substance to enter the bloodstream directly, its effects can be felt by the body much quicker than oral consumption, avoiding the digestive tract. Thus, there is less degradation as it is mainly degraded from the enzymes in the saliva.
