Sublingual tinctures have existed for hundreds of years. Historically, tinctures were alcohol-based as people would use alcohol to extract the medicinal properties from plants, herbs and spices. Today, specifically in the CBD world, tinctures are usually oil-based. Generally, oil-based tinctures are much less daunting on one's palate than alcohol-based tinctures. Tinctures are administered sublingually (under the tongue). By holding the tincture in the mouth, prior to swallowing, the CBD enters the bloodstream more quickly, through the mucous membrane, which allows for higher bioavailability and quicker onset.
Inhaling CBD via vaping or smoking is one of the most efficient delivery methods. As the CBD is inhaled into the lungs, it enters the bloodstream faster than sublingual or oral consumption. CBD products designed for vaping or smoking can come in many different forms -- prefilled vape cartridges, vape additives, concentrates/extracts, hemp flower. Prefilled vape cartridges are convenient as they are compact and discrete.
Topicals are great for CBD's analgesic, anti-inflammatory and anti-spasmodic properties, there are many CBD products in the market. Topicals are ideal because they allows a user to apply the CBD topical to a specific area on the body.
