There is no food additive regulation which authorizes the use of CBD. We are not aware of any information to indicate that CBD is the subject of a prior sanction (see 21 CFR Part 181). Furthermore, we are not aware of any basis to conclude that CBD is GRAS for use in conventional foods. FDA’s regulations in 21 CFR 170.30(a)-(c) describe the criteria for eligibility for classification of a food ingredient as GRAS. The use of a food substance may be GRAS based on either scientific procedures or, for a substance used in food before 1958, through experience based on common use in food (see 21 CFR 170.30).

Unapproved New Animal Drugs
You should also be aware that, as defined in section 201(s) of the FD&C Act (21 U.S.C. 321(s)), the term “food additive” refers to any substance the intended use of which results in its becoming a component of any food, unless the substance is generally recognized as safe (GRAS) among qualified experts under the conditions of its intended use, or unless the substance meets a listed exception. 
Your “Native Pet CBD Oil (150mg, 300mg, & 600mg)” product is a “new animal drug” under section 201(v) of the FD&C Act, 21 U.S.C. 321(v), because it is not generally recognized, among experts qualified by scientific training and experience to evaluate the safety and effectiveness of animal drugs, as safe and effective for use under the conditions prescribed, recommended, or suggested in the labeling.
Vaping involves using a vaporizer (which is typically about the size of a pen) to heat up CBD oil and inhale the resulting vapor. This method of taking CBD requires a bit more of a learning curve than consuming CBD in edible form. (Translation: You may cough the first few times you use a vape pen until you figure out how long to drag on it.)
Two of the most well-known (and most researched) cannibinoids are CBD and THC, or tetrahydrocannabinol. THC is the primary psychoactive compound in marijuana, and it accounts for marijuana’s (in)famous “high”.
CBD oil is frequently incorporated into a wide number of products and can be used in a variety of ways. To date, here are some of the best ways to take CBD:
Gummies and other edibles
What are the Benefits of CBD Oil?
Coughing aside, vaping is one of the quickest ways to feel the effects of CBD oil, because the CBD enters directly into the lungs and then spreads throughout the bloodstream. For this reason, some folks choose vaping to address acute symptoms. While it’s quick to take effect, vaped CBD tends to pass through your system more quickly than it does when consumed as edibles or tinctures.
This method involves a delay between when the CBD is ingested and when its effects start to kick in. Once they do kick in, these effects tend to last longer than the ones experienced via vaping. For this reason, many people with chronic conditions prefer the long-lasting relief offered by ingesting CBD oil.
People who are in need of localized pain relief and/or skin healing may choose to use topical creams, lotions, and salves. For the most part, these products work externally (meaning they’re less likely to produce mental or full-body effects). They’re primarily designed for relief from neck and back pain, arthritis pain, muscle soreness, skin conditions, and so on.
Bottom line? There are several ways to utilize CBD oil. The best method will vary depending on the condition(s) that a person is hoping to treat, their optimal dose, and how long they want to feel CBD’s effects.
