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.
CBD oil is similar to other products in that it is capable of being “watered down.” Some companies will try to eke out a higher profit margin by fooling their customers into thinking they’re getting more for less. It is important to pay attention to the concentration level of the CBD oil you’re buying in order to ensure you’re getting what you’re paying for. Although concentrations of CBD can vary quite a bit across the broad range of CBD products, a quality product will start off having somewhere between 250mg to 1,000mg per fluid ounce. This matters because if you were to purchase a 4 ounce bottle that contained 250mg of CBD, your concentration would be a mere 62.5 mg of CBD per ounce – hardly enough to reap the full benefits of CBD. It’s always important to look at the concentration level of the CBD you’re buying.
