Many people want to know, "what are CRC extracts and should you smoke them?"
There is a lot of confusion about CRC extracts, with some people saying that CRC wax is bad for you. So, what's the truth?
In this article, we'll answer, "what are CRC extracts?", "what is CRC?", and "is CRC wax bad for you?"
By the end of this article, you'll have the information you need to decide if you want to try CRC extracts.
CRC stands for "Color Remediation Column." CRC is a type of cannabis extract that is made using a process called "column chromatography."
CRC was initially started to remove dark colored substances left over from low-quality extraction, which signaled to the consumer its low grade. The process makes the extract appear lighter, as lighter color extracts are associated with high quality. The idea was to enhance the visual aesthetic of a cannabis extract so it would sell better.
CRC has started to become a mainstream practice used by legal and illicit manufacturers to enhance the appearance of cannabis extracts. CRC has evolved and is now used to remove pesticides, unpleasant flavors, and other wanted byproducts.
CRC is most commonly used with butane hash oil. The color of low-grade hash oil changes from nearly “black, or dark brown, to light gold, or even white” when it undergoes CRC.
CRC extraction is a post-extraction process that uses technology to enhance the appearance of cannabis extracts and concentrates.
Column chromatography works by using a column (often a steel cylinder) and packing it with a filtration medium. Common filtration mediums include:
The cannabis concentrate is then pushed through filtering mediums that result in the removal of color-impacting pollutants and other impurities. Pollutants and impurities that can be removed (depending on the filtration medium) include:
One of the downsides of CRC is that it will also strip a concentrate of its terpene content. A way to tell if an extract or concentrate has undergone CRC is the smell. It may smell of chemicals, or may smell excessively fruity or earthy, indicating that it may have had terpene infused to attempt to restore the original flavor profile.
The question "Is CRC Wax bad for you" is up for debate.
A manufacturer uses CRC will say CRC is safe, while a cannabis consumer advocate might not.
The debate is rooted in the fact that cannabis lab tests that deem if a product is safe for consumption do not currently test for CRC filtration mediums. As a result, a cannabis concentrate can be approved for sale despite containing contaminants from CRC filtration.
Some people believe CRC wax is not safe because:
In theory, if a manufacturer properly does CRC extraction, the concentrate could come out with fewer contaminants.
If you are concerned about contaminants in your cannabis concentrates, ask your budtender if the product you're interested in underwent CRC and what filtration mediums were used.
