Fill the dropper with the CBD oil, place the tip of the dropper under the tongue and drip in the desired amount. Let the CBD oil get adsorbed for 1-5 minutes before swallowing it. If you are having a hard time with the dosage or the number of drops when you drip it under your tongue, you can also use a spoon. Just put the desired amount of CBD oil on the spoon and try to put it under the tongue. Just lick off the remaining oil on the spoon. Due to the fine blood vessels and mucous membranes in the mouth, the CBD quickly enters the bloodstream and therefore has a good bioavailability.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
CBD derived from marijuana is a different story, and the law varies from state to state. But as long as you’re using CBD oil that contains less than 0.3 percent THC, you have nothing to be concerned about anywhere in the United States. On the other hand, if you want to take your CBD on a trip outside the country, definitely look into local laws to avoid getting into awkward situations while you’re away.
Currently, the only CBD product approved by the Food and Drug Administration is a prescription oil called Epidiolex. It's approved to treat two types of epilepsy. Aside from Epidiolex, state laws on the use of CBD vary. While CBD is being studied as a treatment for a wide range of conditions, including Parkinson's disease, schizophrenia, diabetes, multiple sclerosis and anxiety, research supporting the drug's benefits is still limited.
