    How Old Do You Have to Be To Buy CBD in the U.S?

    For the person to be able to purchase CBD products in the U.S, they must be an adult. The adult age of a person in the U.S is 18 years old. At this age, people are believed to have control over their actions and affairs and are responsible for making their own decisions. This article explains how old an individual should be for them to buy CBD in the United States.

    CBD is one of the main chemical compounds found in the cannabis hemp plant. This cannabinoid does not have psychoactive effects, so it can't get you ‘high’. It is known for its many potential benefits, such as dealing with cancer-related symptoms, acne, inflammation, pain, depression, stress, and other health conditions.

    Types of CBD

    There are three types of CBD depending on their cannabinoid content and extraction process.

    CBD Isolate

    It is an isolated form of CBD. It is made of pure CBD and contains no other plant chemical compounds. It is extracted by removing all the other plant compounds leaving pure CBD behind. Depending on the extraction process, the high-quality CBD is made of 99% pure CBD, which helps maintain its potency even when added to other substances like food or drinks.

    CBD isolate is recommended for people who want to get the CBD benefits without getting THC effects. This type of CBD does not show in drug tests, so it can be used by people who have to undergo a drug test. It is flavorless and odorless, so it can be used by people who don't like flavors.

    Full-Spectrum CBD Oil

    This type of CBD contains all the chemical compounds in the cannabis hemp plant, including a trace of THC. The THC compound has psychoactive effects responsible for getting people 'high'. It contains other cannabis compounds like terpenes, flavonoids, fatty acids, and other minor cannabinoids. These compounds play a greater role in improving the general benefits of CBD. Some terpenes have anti-inflammatory, antifungal, and anti-pain properties, which help deal with some health conditions like chronic pain.

    Combining different cannabinoids in one product brings what people call the ‘entourage effect’ theory. Some people prefer using this type of CBD for the entourage effect.

    Broad-Spectrum CBD Oil

    This type of CBD is between CBD isolate and full-spectrum CBD. It is made of all the cannabinoids except the THC compound. Other compounds such as terpenes, fatty acids, flavonoids, and minor cannabinoids are available, bringing the 'entourage effect. The entourage effect is brought by the other cannabinoids working together to boost the overall effects of the CBD. People who want to benefit from the entourage effect without the THC prefer this type of CBD.

    How To Use Full-Spectrum CBD Oil?

    All types of CBD come in different forms, administered in different ways. CBD products come in forms like edibles, topicals, and tinctures. The following are different ways of administering CBD oil:

    CBD Capsules

    CBD capsules come in a fixed amount of CBD, making it easy and convenient to dose. The recommended dose is indicated on the label on the capsules, and one should take them as directed. Hawes et al. (2020) explained that CBD capsules might take up to an hour before showing effects because they must undergo digestion first. The benefit of CBD capsules is that they ensure you get the same dose each time.

    Taking Tincture Sublingually

    This method of administering CBD oil is by placing the required amount of CBD oil under your tongue. It is done by using an eyedropper which helps measure the CBD dose. The dropper squeezes the required amount of CBD under your tongue and holds it there for seconds before swallowing. This method produces desired effects very quickly because CBD gets absorbed into the bloodstream directly. CBD tincture can also be added to a drink or food if you don't like its earthy taste.

    Use CBD oil Topically

    Evans (2020) explained that this method of CBD administration involved applying the massage oil to one's fingers and massaging the affected area. It is commonly used in treating achy muscles and joints and chronic pain. It may take 30 minutes to a few hours to show its effects.

    CBD Edibles

    CBD edibles are chewy candies, treats, and other food products infused with CBD. Each edible comes with a fixed amount of CBD. They may take 2-4 hours before showing effects, and they may not be effective like other CBD products because they must go through the digestive system before entering the bloodstream.

    Vape CBD Oil

    It can be the quickest way to feel the effects. Vaping CBD involves using vape pens which convert the oil into a vapor that can be inhaled. Although vaping CBD oil brings the effects faster than the other methods of CBD oil administration, it is associated with lung and respiratory issues.

     Is CBD Legal in the U.S?

    CBD containing less than 0.03% of THC is legal in the U.S. This is because; it is believed that 0.03% content of THC is not enough to get a person 'high'.

    How Old Do You Have to be to Buy CBD in the U.S?

    In the U.S, the adult age is 18 years, and a person is allowed to make their own decisions and be responsible for their own mistakes. The regulations of CBD products are not so clear because CBD and legal marijuana landscapes are still to navigate. The right age for the person to be able to purchase CBD in the U.S is 18 and above years old. Berg et al. (2020) explained that there is no official federal legal age for purchasing CBD because CBD laws differ from state to state. Learn more about what does cbd taste like?
