CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
THC is found in large quantities in cannabis, or what most people think of as the marijuana plant. Unlike cannabis, or marijuana, hemp contains low concentrations of THC. CBD Oils are generally made from the hemp plant so they contain high levels of CBD and trace levels of THC. As a result, CBD provides a less controversial alternative to THC for health benefits.
In 1970, the U.S. government passed the Controlled Substances Act, a statute that regulates all cannabis, including industrial hemp. However, the definition of marijuana was lifted from the existing 1937 statute and adopted without any change. This definition excluded certain parts of hemp — sterilized hemp seed, hemp fiber, and hemp seed oil — from regulation.
And we have a long way to go before we fully understand the relationship between CBD and pain regulation. But strong anecdotal evidence, combined with multiple lab tests and even some clinical trials, have established that CBD holds a lot of promise for pain relief. Or in science-speak, CBD “represents a novel class of therapeutic agents for the treatment of chronic pain.”
While medical marijuana is grown to be high in CBD for the treatment of specific ailments, the THC content can vary dramatically, sometimes getting as high as the CBD content. For an excellent example of the types of marijuana you may find in a licensed dispensary, see this Strain Book. It shows you the types of plants, the percentages of CBD and THC, and even the taste and effects of the stain.
CBD may be best known for its relaxing, calming effects. CBD reduces autonomic arousal, having the inverse effect of THC on the body. CBD’s anti-anxiety effect is why many in the cannabis community talk about how CBD relieves paranoia, although that is not scientifically proven yet. CBD is also known for its anti-nausea and pain relieving effects. It really depends on why your body’s specific needs and the quantity in which you take CBD.

Martin Lee, co-founder of Project CBD, told Leafly that hemp fiber and seed contain no usable amounts of cannabinoids. “Cannabidiol can’t be pressed or extracted from hempseed,” he writes. “CBD can be extracted from the flower, leaves, and, only to a very minor extent, from the stalk of the hemp plant. Hemp oil start-ups lack credibility when they say their CBD comes from hempseed and stalk.”
February of 2017, a Hawaii government committee passed a bill to decriminalize industrial hemp, removed it from the state’s list of controlled substances and excludes growing, possession, processing and the sale of industrial hemp from civil and criminal penalties. No license is needed to grow and the crop is treated as other plants such as tomatoes, fruits, and other vegetables.

As mentioned above, CBDPure is a natural oil extracted through cold pressing and CO2 procedures from Cannabis sativa. Specialists have identified over 80 compounds known as cannabinoids. Their research so far showed that CBD is the predominant cannabinoid, accounting for over 40% of the cannabinoids concentration. It is also the most beneficial for human health, at least from the cannabinoids studied so far.


CBD is the major non-euphorigenic component of Cannabis sativa. Some research is beginning to show that CBD is different than other well-studied cannabinoids. All cannabinoids function as ligands, meaning they dock onto the binding site of a protein and have the ability to modulate a receptor’s behavior. CB1 receptors are widely distributed, but are particularly abundant in areas of the brain, including those concerned with movement, coordination, sensory perception, emotion, memory, cognition, autonomic and endocrine functions.
