![]() ![]() Alcohol-based extraction also allows for the product to retain a longer shelf life, as the alcohol acts as a preservative. Alcohol-based extraction methods are often used due to being one of the easiest and quickest ways of creating a concentrated compound product for the medical market. Tinctures are alcohol-extracted concentrates and are quite high in THC content. Bubble hash is similarly extracted in the sense that it uses cold temperatures during the process through ice-water extraction. This allows for more terpenes to be retained within the concentrate before they dry out to create a flavourful product (this still depends on the flavour of the flower being used) compared to concentrates that have come from bud that has been allowed to cure before extraction. Resin is a naturally forming sap from the plant whereas live resin is a cannabis concentrate that uses buds that have been freeze dried for the extraction process. CBD oil from hemp only contains traces of CBD and is a food supplement (containing vitamins such as magnesium) rather than a medical grade product. ![]() Some CBD oil is made from the THC carrying plant whereas others are made from hemp which has less than 0.3% THC. Taken orally through dropping under the tongue, as this is the best method for CBD absorption, this product is very popular for pain relief, anti-inflammation, for conditions such as epilepsy and other medical uses. Typically, this is extracted then distilled and separated from other compounds to create a pure CBD oil. CBD oilĬBD oil is a concentrated oil that contains the non-psychoactive component of cannabis only. These oils can be high in THC content, containing anywhere between 70-90% THC and higher in some cases. However, this process does – almost always – leave traces of butane in the product. This process uses high pressures to extract compounds from the plant by stripping them and is fairly good at retaining the terpenes from the plant – producing a tastier final oil product. BHO concentrateīutane hash oils come from the hydrocarbon extraction process. Rosin also retains terpenes so is just as flavourful as other kinds of cannabis concentrates. This concentrate is totally solvent-free so can give patients peace of mind if they are concerned about what is in their medicine. As the industry has grown there are now industrial size presses that can obtain rosin on a large scale. Rosin is extracted directly from the flowers – traditionally made from the heating and pressing of hand extracted compounds. The difference between extracts and distillates is their purity – products that have been distilled are, by nature, much purer than extracts. Short path distillation is a specialised form of distillation that creates potent concentrates and a process called ‘winterisation’ removes unwanted compounds such as lipids. Distillation uses a heating and collection method of separation and this is a more specialised element of the commercial concentrating process. More modern options for extraction today include CO2, hydrocarbon and the cryo-ethanol process. Ice-water extraction has also been used for many years to make concentrates. The remaining products can then be heated and pressed to create a rosin extract. This is a simple way of separating compounds by grinding the marijuana and sifting it through a metal gauze (or on a larger scale through a silk screen) – producing what is called ‘dry sift’ or ‘pollen’. Traditionally, solventless extraction is done using kief boxes or grinders. There are two kinds of extraction methods – solvent based and solventless. In order to make a concentrated oil, compounds contained in the plant need to be extracted and distilled (or refined). However, some concentrates contain very high amounts of the psychoactive component THC – up to 99% in some cases – so, it is vital for patients to properly understand the medicine they are using. Oils that contain THCa can be used without any psychotropic effects as it is only when the THCa is heated that it turns into THC. However, contrary to popular belief, THC also has many medicinal qualities and more research is being done into the combined effects of THC and CBD for therapeutic use. One kind of concentrate in particular – CBD oil – has gained a lot of popularity over the past few years for its medicinal value. ‘Concentrate’ simply means concentrated cannabis compounds derived from the raw plant. Understanding the difference between the types of cannabis extracts and distillates can help patients get the best out of their medicine. © iStock/eskymaks Did you know that a better understanding of cannabis concentrates can improve patient experience when using cannabis medicines?Ĭannabis concentrates can offer a lot more value for money in terms of efficacy, making them a popular choice among patients. ![]()
