Pros and Cons of the Dry Ice Extraction Method

In simple terms, CO2 cannabis extraction uses pressurized carbon dioxide (CO2) to pull CBD (and other phytochemicals) from the plant. CO2 acts like a solvent at certain temperatures but possesses none of the dangers. While it is safe and effective, it also involves expensive equipment which freezes the CO2 gas and compresses it into a supercritical cold liquid state.

Moreover, CBD is known to inhibit the functioning of the FAAH enzyme that directly acts on the CB1 receptor and enables THC to produce its psychoactive effect. CBD has established global interest among industry specialists, and its discovery has prompted medical experts to take a closer look at the benefits.

CBD oil is especially popular. It is used to treat a host of illnesses and works by interacting with the endocannabinoid system (ECS) without providing users with a ‘high.’

3 – The Dry Ice Extraction Method

For extraction, the liquid is added to the plant material. The extraction liquid will strip away the cannabinoids and flavor from the plant material but will probably take some green colorings too. Once enough cannabinoids have been extracted, heat the liquid to evaporate it down to the CBD base oil.

Without further ado, let’s look at the 4 most common CBD oil extraction methods.

It is essential to understand the various CBD extraction methods as they significantly impact the quality of the end product, not to mention your health. We don’t recommend utilizing the solvent method because it is dangerous to make and is also more likely to cause health problems. The cost of CO2 supercritical extraction means it is not possible for 99.9% of readers, but it is an excellent, safe, and efficient method.

This form of CBD extraction is actually divided into supercritical, subcritical, and ‘mid-critical’ categories. But supercritical is by far the most commonly used. In fact, it is the most regularly used extraction method of all because it is safe and provides a pure end product.

Cannabis is an herbaceous flowering plant of the Cannabis genus (Rosale) that has been used for its fibre and medicinal properties for thousands of years 1,2 . In recent decades medicinal cannabis has become legal in several jurisdictions and the possibility of legalisation is being explored in many more 3,4,5,6,7,8 . The chemistry of cannabis is rich and varied; it includes phytocannabinoids, terpenes and phenolics, and each of these classes contain compounds with biological activity 9 . The cannabinoids, in particular, Δ 9 -tetrahydrocannabinol (THC) and cannabidiol (CBD) have been the main focus of bioactive research. These cannabinoids are naturally present in planta as their acid analogues Δ 9 -tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA). THCA and CBDA are the major cannabinoids found in cannabis although more than 90 cannabinoids have been reported 9 . The acids degrade naturally to the corresponding neutral species at a slow rate via non-enzymatic processes 10 . Decarboxylation is facilitated by heating (e.g. when smoked) (Citti et al. 2018). Many medicinal cannabis preparations are consumed in an oil or are made from an extracted resin and not smoked. In this case, the dried cannabis material must be ‘cured’ prior to, or during, extraction (i.e. heated for a specific time and temperature to ensure maximum decarboxylation). THCA is the main psychoactive cannabinoid followed by cannabigerolic acid (CBGA).
